ABS housing
Anti-locking brake systems for carsare now an integral part of the automobile industry. Electronicallycontrolled braking systems preventthe wheel from locking.
ABS housings are safety related components which are subject to acpk analysis. The increasing demandsfor tolerances, burr-free results andan extremely low Si content in thematerial make cutting operations achallenge. In particular extremelyhigh stipulations are made formachining bores in engines andpumps. Decisive factors for success-ful production are surface finish,accuracy, concentricity and inter -relating positions. For bores in pumpsmaximum tolerances of IT 7 with asurface finish of Ra 0.2 µm apply.
Solid carbide tools for pre-machiningtogether with tools with fixed PCDblades and fine boring tools withguide pads are typical tools for thesecomponents.
PCD is a fascinating cutting material,which has ever since its development,more than 30 years ago, won an extre-mely high importance for the machi-ning of aluminium, also increasingly ofCFRP and other modern materials.MAPAL WWS was part of thedevelopment right from the verybeginning and can call itself a pioneerof the introduction of PCD inmechanical machining.Decisive was the introduction of theeroding process for the machining ofPCD blades. It was with that possible toeconomically machine this extremelyhard cutting material with highest pre-cision.
In combination with the HSKconnection the manufacturing andutilisation of rotating tools becamepossible with high complexity for themachining of aluminium and non-ferrous metals. The results are excellenttool lives and with that the basis forthe rational manufacturing, even ofcomplex components.
Brilliant – tools with PCD (polycrystalline diamond)have captured the world!
The handling of the tools generallyproduced in monoblock constructionform is very simple. Care must be takenthereby of the precision of the machinespindle and the tool clamping.
MAPAL has built up a world-widenetwork of companies for technicalconsultation for the designing andutilisation of PCD tools, as well as theservicing, tipping and optimisation.With this a highly qualified and promptservice is guaranteed for these tools –also world-wide. This guarantees thehuge success story for PCD tools willbe continued.

When the first polycristalline diamond(PCD) was introduced at the beginningof the 1980s it brought a revolution inthe development of cutting materialbut also a revolution in tool manu-facturing.How did this come about?At approximately 1,500°C and at apressure of approximately 60 kbar anexceptional quality of synthetic dia-mond, together with a carbide substrate, was subjected to a sinteringprogramme. An extremely complicatedchemical process then followed.Cobalt, a chemical component of car-bide, acted as a catalyst and caused anintensive structural change in the indi-vidual diamond particles. This inten-
sive structural change a sensation,providing a cutting material with thehardness and wear resistance of dia-mond, the hardest material on earth.The carbide substrate gave the cuttingmaterial the necessary strength andunder day-to-day machiningconditions offered the best possibleconditions for brazing the blades ontosuitable carriers. At the beginning theblade size for these so-called PCDblanks was limited but sizes are nowavailable up to a diameter of 75 mm.
A cutting material of this hardness wasa tough nut to machine, in the truestsense of the word. The familiar grind-ing methods were not suitable so new
PCD –Diamond as a high-tech product
ones were developed and refined to perfection. Wire erosion and laser technology are now state of the art. The originally limitations to cuttingforms and geometries no longer exist.
In just 30 years PCD has developed intothe super cutting material for machin-ing non-ferrous metals and non-metal-lic component materials and it would be impossible to imagine modern pro-duction technology without it.

Just as with conventional cuttingmaterials, such as carbide, there areconsiderable variations in quality inthe cutting edge. Various machiningtasks and the variable abrasiveness ofthe material require variations in cut-ting materials. The results of our manyyears of experience in diamond bladeshave been an amazing range of modifi-cations using different PCD grades.Different grain sizes in the microstruc-ture of the diamonds can be variedwith a selection of coating thicknesses
combined with a number of blanksizes. Irrespective of the machiningtask for which you require a PCD blade,this allows us, to select the right dia-mond quality.

ideas, products and servicesConstantly increasing demands onmodern cutting operations require amodern, highly flexible approach fromthe tool manufacturer. Our compe-tence in dealing with PCD cuttingmaterial is reflected in day-to-day tooldesign.The ongoing objective is to combineseveral machining tasks with one tool.For the user this means that unproduc-tive ancillary time for tool change isdispensed with.Not infrequently tool concepts occuras a result of this motivation which areunique in design. We are becomingmore competent in this way thinking
and acting as a result of high produc-tion reliability when manufacturingthe tools. However, constant develop-ments in machining PCD are not suffi-cient in themselves. Any parameterswhich are required for tool manufac-turing need to be constantly drivenforward. Examples are modern brazingmethods and filigree balancingsystems. The high potential perform-ance by our products, enhanced by theenormous technical competence of ourapplication specialists, are guaranteesfor success in solving the tasks whichare faced.

Precision –the perfect geometry for every toolThis principle is a thread runningthrough all areas of the organisationlike the symmetry line through thetechnical drawing of a tool. With thesame precision as that required in thedetailed design of every blade, theimplementation of these details iseffected in all the production areas.Manual work stations are thus in har-mony even in the most modern opera-tions with fully automatic productionunits. An intelligent computer systemfor controlling production routines and
constant quality assurance – all build-ing blocks which fit perfectly together.The highest priority for all the workstations is precision and quality. Com-plete documentation of all the pro-cesses and inspection procedures toaccompany the process are the basisfor the constantly high quality level of all tools. The result of all theseendeavours is rational and reliableproduction at the customers’ works.

The precision on the tool cannot betried out but simply produced. It istherefore essential that even duringthe preliminary sequences, such aswhen separating PCD sections from theblank or brazing, work is carried outextremely carefully. Only tools whichhave been perfectly produced rightfrom their basic assembly on the toolcarrier can achieve a tolerance range ofa few microns with high precisionoperations such as electrical dischargemachining or PCD grinding.

PCD tools –from precision gun boring to circular milling
Gun boring – the challengeThe bore defines the func-tion. In almost all cases thequality of a product dependson the precision of the boreswithin it. Both static anddynamic tasks and functionsare effected by the bores.For tools for manufacturingbores of this kind the nameMAPAL WWS is a mark ofquality and economics. Thealmost unlimited designoptions for the PCD blade forthe relevant tools presentunimaginable opportunities.Several machining tasks canbe easily combined with onetool. The saving of tools andelimination of unproductiveancillary times improve theproduction economics at thecustomers’ works.The manufacture of a step-ped bore for which all thechamfers and radii have tobe machined is solved withone tool. The concentricityof the individual steps isguaranteed. Even machining
axial grooves or spot facingmounting faces can be eco-nomically resolved with oneboring tool. As no radial for-ces affect the component,requirements for flatness orangular precision can be metmany times more easily thanwith conventional turning orcircular operations. Machin-ing of a complex externalcontour, for example on adome, is another applicationfor efficient drilling opera-tions. By designing the toolin the form of a bell, the com-plete machining operationcan be carried out in theaxial direction. Even the large
allowance which is fre-quently present with appli-cations of this sort, can besafely dealt with. Cuttingdepths of more than 4 mmper side are not infrequentlyachieved. Irrespective of theproduct – whether this is anefficient combustion enginefor a sports car or a set ofmixer taps for the bathroom– the bore defines the func-tion.
Circular milling – the formis decisiveAs always it is an advantageto carry out certain opera-tions by circular milling.When machining hydraulic
parts control edges have tobe produced in the relevantpiston bore. Often severalgrooves are required whichare axially offset to oneanother. Sometimes all theseslots have different forms.These are decisive factors forusing PCD tools. Frequentlythis allows several opera-tions to be combined withone tool. The complete formis then produced in onecircular movement on themachine.This is only possible becauseof the harmonic cuttingbehaviour of the PCD blade.Cutting forces are limited toa minimum and the tenden-cy to produce chatter doesnot arise. Radial grooves onexternal contours can beeconomically produced bycircular milling. For this thetool is designed as a bellwith the blades located onthe internal contour of the

tool. With a radial deflectionof a few millimeters thegroove can be produced witha very slight circular move-ment.Because the PCD does notproduce burring the manu-facture of threads is increas-ingly significant. Cross holeswhich occur in thread flanksset extremely high demandsfor follow-on machining onthe parts. By using PCDthread milling cutters sub-sequent machining is totallyunnecessary.
End mills – pure perform-anceEnd mills with PCD bladesare currently still attractinglittle attention for use onmodern machining equip-ments. The large range ofstandard end mills in solidcarbide is probably theexplanation for this. How-ever, it is in this particulararea that there are numer-ous arguments for using PCDend mills. Costly eroding toproduce forms, such as thoseproduced from graphite orlarge dimensioned integral
components for aircraftproduction, require long toollife and reliability from themilling cutters used.Particularly highly abrasivematerials cause wear to beproduced unchecked on mil-ling blades for solid carbidemilling cutters. The result isthat distortions in geometryoccur on forms or the requir-ed corner radii are not pro-duced. It is in these casesthat the enormous potentialof PCD end mills can be
demonstrated. The recognis-ed advantage of long toollife for PCD cutting materialcan be directly applied.Time-consuming reworkingon formed parts or prepara-tion of sister tools is no lon-ger required. The specificallyadapted standard program-me of PCD end mills is de-signed directly for theseapplication areas.

PCD tools – production reliability for pre-machining and finish machining
Face milling – the classictoolSimple but sturdy construc-tion combined with the facil-ity to change and adjustmilling cartridges at extreme-ly low cost makes this pro-duct a classic among PCDtools. Numerous applicationprovide daily proof of thereliability of the milling headsystem. Logically developed,adapted to the needs ofmodern cutting, the range ofuses stretch from conven-tional milling operations tohigh speed cutting. The intel-ligent directing of the cool-ant through the tool alsoallows successful use ofminimal lubrication. Because
of the high diversity ofgeometry in the standardrange of milling cutters, theuser is always able to use theprefect blade for differentcomponent materials. Themilling cartridges, which canbe set axially to high preci-sion, along with the appro-priate tool holder, achievesurface finishes and tool lifewhich speak for themselves.
Reaming and fine boring –precision to perfectionIn addition to PCD precisiongun boring tools with fixedblades the product program-me for reaming and fineboring includes precision
tools with replaceable, dia-mond-tipped blades andguide pads and PCD-tippedmulti-bladed reamers. Fortools with guide pads, inaddition to PCD blades forlong tool life and particular-ly good surface finish, dia-mond guide pads are alsoused for their extremelygood sliding properties andwear-resistance.
Because of MAPAL’s long-established principle, thesetools, which can also beused in the HSC area, areparticularly impressive inhigh precision areas.

But it is not only in alumin-ium machining that MAPALtools are tipped with PCD asa cutting material for ream-ing and fine boring. Inno-vative tool solutions for useon cast iron materials allowfollow-on operations previ-ously required to be dis-pensed with, such as grind-ing and honing.MAPAL tools for reamingand fine boring have becomethe byword for absoluteprecision and reliability inmodern production through-out the world.
Gun boring and milling –with ISO InsertsA further product area isspecial tools with diamondtipped ISO Inserts. Variousmounting and adjustmentoptions for the blades en-sure exact concentricity andtherefore maximum tool life.The extensive experienceand numerous innovativeideas provided by the MAPALspecialists produce extreme-ly successful tool concepts.
With HPR high precisionreamers MAPAL offers a pro-gramme of fixed PCD tippedmulti-bladed reamers forfine machining bores.Because the coolant is sup-plied directly onto the blade,the HPR reamers are alsowell suited for use withminimal lubrication. In con-junction with the HFS® HeadFitting System, concentricityand changeover accuraciesare achieved to extremelyhigh precision and providethe prerequisite for newdimensions in modern highperformance cutting.

From experience –guidelines and cutting values in practice
PCD gun boring tools are individual toolsolutions which are specially designed fora specific application. To present recom-mendations for cutting values whichcover all possibilities in a table would beunrealistic. Too many factors have a directeffect on the machining result. Differentwall thicknesses, cross bores or interrup-
tions can affect the system. The valuesshown in the diagram should therefore beregarded as guidelines. MAPAL WWSspecialists would be pleased to offer youtheir knowledge and experience to findthe solution to special requirements.
The highest priority forrough boring with PCD toolsis the multiple cutting func-tion of the tool. The run-outerror measured for the toolon the machine spindleshould not exceed 5 µm. Forcritical bores or fits thisshould only be a maximumof 3 µm. To monitor thiscriterion concentricity checkpoints are located on thetool right next to the blades.Here the user can have adirect influence on the tool’sconcentricity. The accuracy
of the cutting track for theblades can be improved bymeans of axial and radialadjustment screws, forexample on modular toolholders, or simply by turningthe tool in the hydraulicexpanding chuck.

Milling with PCD blades – aneven more economic solutionJust as with milling thisproduces all the advantages ofthe diamond blade – withoutcompromising the machiningresult. The extreme hardness ofthe diamond combined withthe toughness of the carbideoffers the best combination foreffectively milling. These prop-erties are further enhanced as aresult of the highly polishedchip surface. Low forces whencutting off the chip and thereduced coefficient of friction

task. Small milling cutter diameters withlarge feeds would be debatable, just asroughing with a tool diameter of 20 mmin conjunction with a low cutting depth.MAPAL WWS specialists are happy to beof assistance with their knowledge andexperience in solving special requirements.
The PCD HP-EndMill is characterised bythe high multiple cutting performance ofthe individual cutting edges. Productiontolerances of ≤ 5 µm for radial and axialrunning ensure the actual multiple cut-ting performance. Thermal expandingchucks or mechanical pneumatic chucksare the best means of clamping thesetools. One further important point for use, particularly under HSC conditions, is balance. Optimum conditions areachieved if the milling cutter and the tool holder are balanced together.
For end milling with high chip volume thecutting values are adjusted to the poten-tial performance of the machine. Becauseof the significantly lower cutting forceswith PCD milling cutters compared to sol-id carbide tools, settings or teeth feedrates can be increased to reach the limitsof the machine’s performance. Selectionof the appropriate setting should ofcourse be made at a sensible level for the

for his machining operationbut his machine is restrictedby the maximum possibletool diameter. As a specialsolution MAPAL WWS offerslaterally flattened millingheads for this – so-calledbeam milling cutters. Withspindle orientation themachine can then be ‘out-witted’.
Complete machining opera-tions, with which faces andspacing can be produced in asingle milling pass, are notunusual. For these applica-tions the classic milling headsystem is then used as a discmilling cutter version.Face milling operationswithin housings or millingoperations in which theeffective working point is ata distance from the spindlenose often lead to vibrations.Here the PowerFix seriesvariation with special vibra-tion damping elements with-in the milling cutter bodyare particularly good. Byusing this tool solution theoperation often becomeseconomic for the first time,even under HSC conditions.

The PowerMill series, the classicamongst all the milling heads, hasbeen constantly adapted to meet thegrowing demands of cutting operations.The main difference to the EcoMillseries lies in the milling cartridge. With the PowerMill series the millingcartridges are designed with largerPCD blades. In addition to the greatercutting depth up to a maximum of 4 mm, this also allows regrinding.Because of accurate production to fitthe aluminium body, the high precisionmilling cartridge guarantees perfectcircular movement of the blades.

the aluminium tool body. Centrifugalforces which occur during machiningare compensated for by a precisiondovetail guide. The new arrangementof the milling blades with integralswarf protection plate clearly increasesthe life of the milling cutter body. Per-fect surface finish is achieved with thismilling cutter as a result of the sensi-
tive and effective wedge adjustment onthe blades in the Z direction. Initiallydesigned for finishing operations, thismilling head is notable for extremelyquiet running which it easily achievesdespite the high feed rates.
The EcoMill series, with the EcoSpeed,EcoFeed and EcoFix systems, representa new dimension in face milling forHSC operations. The series includesnumerous innovations. By usingreplaceable milling cartridges thereduction in logistics costs from handling is also impressive, likewisethe positioning of the milling blade in

Face milling heads PowerMill and EcoMill – easy handling for high precision results
• Locate the face milling head in the setting fixture• Fit the milling cartridge on the basic body using
holding screws • Pre-adjust the milling cartridge with adjusting
screws
• Tighten holding screws with 14 Nm
• Finely adjust the milling cartridgewith adjusting screw
With the PowerMill series fine adjustment is carried out after the millingcartridge has been finally fitted and the appropriate torque applied. The adjust-ment screws which have been specially developed for this series allow the bladesto be perfectly adjusted. The design of the milling cartridge allows an adjustmentrange of at least 1 mm.
PowerMill series – fine adjustment with adjusting screw
The efficiency of a Milling Head Sys-tem is not just demonstrated by theclassic assessment factors. Cuttingresults, tool life or surface finishachieved and even tool planning are ofprime importance. A further importantfactor for a successful system, how-ever, is handling. A minimum of ex-tremely simple hand movements mustbe achieved to prepare the millinghead at the tool setting stage for useon the machine. It is not unusual, par-ticularly in large cutting organisations,
to also recondition the face millingheads at the end of their life within thecustomer’s own tool managementsystem. A decisive factor here is thathigh precision blade setting can becarried out with the least possibleamount of work. It is only in this waythat reliable batch production can beobtained even with reground millingcartridges.

Based on this technology, a new type of wedge adjustment was developed for theEcoMill series. Here the adjusting element has a wedge-shaped surface which liesdirectly against the milling cartridge. By turning the right-hand and left-handthreaded spindle the axial running can be effortlessly set within the required high-precision range. Combined with the easy handling, the accuracy to beachieved surpasses all the previous results.
• Position face milling head in setting fixture• Fit milling cartridge with holding screw onto basic
body• Adjust milling cartridge roughly with adjusting
screw
• Tighten holding screw at 8 Nm • Finely adjust milling cartridge with adjustingwedge
EcoMill series – with wedge adjustment
A decisive factor for this is the preci-sion with which the milling tool bodyand also the milling cartridges arethemselves manufactured. Costly set-ting devices, time-consuming settingprocedures and expensive settingequipment are not required. One set-ting fixture, whose construction isdesigned for the primary requirement,plus a precision indicator, is quitesufficient.
High precision fine adjustmentThe basis for perfect finish machiningof a milled surface is the exact axialsetting of all the blades to maximumprecision. This factor was given partic-ular attention when designing thePowerMill and EcoMill series. Whilewith conventional face milling cutters,whose technology is often based onclamped blades, these have to be posi-tioned in 3 planes in relation to eachother, here setting in one direction isquite sufficient.

This product family is particularly intend-ed for face milling operations with highallowances. Cutting depths are possible upto 10 mm. In addition because of the largenumber of teeth exceedingly good feedrates are achieved. This is of particularadvantage for machines with low spindle
speeds. Vibrations which occur duringmachining, which are also caused by thecomponent, are absorbed by the massivetool body and not passed on to the surfacebeing machined.

Reconditioning and service
Effective production calculationsthroughout the whole of the life of thecomponent require maximum reliabili-ty in calculation data. It is thereforehelpful for the planning department ifreconditioning costs which occur formachining tools are already known inadvance or have even been specified.The removal of work on the logisticsfor processing repairs also gives theuser the opportunity to concentrate onhis own activities. It is exactly theseaspects which produced the motiva-
tion for a modern repair managementsystem. The preparation of basic toolholders combined with the multipleapplication properties offered by PCDblades provided the breakthrough forthe Fast Repair System. Constantavailability of ready-to-use specialtools increases production reliability,raises productivity and as a resultensures that each batch producerremains competitive in the market.

The application of the repair systemfollows on from the end of the optimi-sation process in batch production.Subject to the tools which alreadyexist, the need for repair carriers iscalculated on the basis of productionfigures and other parameters. Thesetool carriers are issued accordingly atthe first regeneration stage and arethen constantly available. For subse-quent reconditioning work the PCDblade from the original tool is changedover onto the new carrier and re-fittedin parallel. This means there are doublethe number of tools in circulation. Theexcess is kept in a consignment stockwhich can be set up on site and is thenavailable to the customer. This resultsin ongoing availability for all specialtools, which also safeguards the conti-nuity of the batch production againstunforeseen events (e.g. crash).

performance level right from the startMilling Head Management – A guaranteed
Milling with a face milling head isfrequently the first operation inmachining a component. For thisreason the operation needs to beapproached with extreme caution.Varying allowances, caused by thedifferent loads of blanks, sometimesnot yet surface treated, have a directeffect on the face milling tool.
The milling result achieved, however,represents the basis for further boremachining. Production reliability withthis process is the basis for trouble-free complete machining of thecomponent. The user must be able todepend on this tool, particularly afterregeneration.

Cleanness, care and precision are themain factors at the forefront of recon-ditioning milling heads. Once disman-tled the tools are basically cleaned,worn parts changed and the systemthen reconstructed from scratch. Wornparts are passed on for the repair pro-cedure and the tool is refitted withregenerated blades from stock. Afterassembly with the appropriate millingcutter holder, the milling cartridges areset to the original setting dimension.The customer is then given back a toolwhich is immediately ready to use.
Length adjustments are not required.The tool will easily achieve the sametool life as before.
If a milling head managementagreement is undertaken, we willguarantee this work is carried outwithin 48 hours.

Pick-up-Service – Direct to the customer
An effective order processing system,both for new orders and for recondi-tioning, requires all the working prac-tices to run perfectly. As a result thedespatch method should also not beoverlooked. Prompt deliveries of theproducts at firmly agreed times makehandling easier for the user. This can beachieved by introducing a Pick-up sys-tem. The tools are collected or returneddirectly from the customer by ourtechnical service engineers.
A special advantage is produced forlarge organisations if difficultdespatch routes and unnecessarilylong stoppage time can be avoided.This eliminates long-winded process-ing of deliveries by parcel services andguarantees “Just in Time” despatch.
More information on the countries andregions in which the Pick-up-Service isavailable can be obtained from yourMAPAL representative or from one ofthe MAPAL branches.

To machine valve bodies for automatictransmission systems up to 50 tools areused. The position of the bores, the clampingpoints and the relatively small size of thepart compared to other workpieces makemachining a challenge. However, absoluteprecision bores are the prerequisite for thepart to function perfectly. The valve bodybores on the face side, with up to four steps,and possibly an additional contour, pass forexample through ribs just a few millimetersin depth. Sometimes these features have tobe produced in solid material.
MAPAL supplies high precision tools for allmachining steps, whether for face machin-ing, for pre-machining and gun boring, or forthe final finish machining.

Cylinder head
Nowadays cylinder heads are producedalmost entirely from aluminium. For thisreason PCD as a cutting material plays adecisive role in machining these parts.Overall PCD is gaining importance in theautomotive industry as a result of theincreasing number of light metalcomponents.
In addition to the parent bores and sparkplug bores, plus the high precision cam shaftbearing bore, particular requirements aremade in the cylinder head on valve seat andvalve guide machining. Here concentricity,roundness, accuracy of form and surfacequality play the decisive role in trouble-freevalve function – a vital requirement forachieving optimum engine performance.
88
Transmission housingWhether tools with fixed blades for pre-machining and finish machining or fine bor-ing tools with high precision adjustment, therange of products offers solutions for everytask. The principal production tasks on trans-mission housings include selector shaftbores and bearing bores which are subject tostatistical production requirements in form,position, surface finish and bore diameter. These bores are partly interrupted by ventila-tion or oil slots – something which places aspecific demand on the tool. With MAPALprecision tools these machining tasks arereliably and precisely solved within therequired tolerances.
Competence in practice
MAPAL has supplied precision tools for thewide diversity of types of clutch and trans-mission housings for more than 30 years andas a result holds a special position in theindustry through the knowledge and experi-ence it has gained.

The various versions of steering gear boxescan extend to lengths of up to 350 mm andare therefore a special challenge to the toolmanufacturer. In particular it is important toensure the required quality of the recipro-cating piston bore with regard to surfacefinish, concentricity and straightness withreliable production results. Large chip spacesand intensive cooling make sure the numer-ous chips which are produced are removed.One special feature when finish machiningthe reciprocating piston is in the simultane-ous machining of various diameters with dif-ferent defined and specified surface finishwhich lie within a specific range. This meansthat a surface which is too good does notalways corresponds with the productionconcept.
MAPAL also demonstrates high flexibilityand wide experience in project planning forthese complex components.

Machining is mainly carried out in 2 clamp-ing positions on multi-spindle machiningcentres with high performance MAPAL WWStools. For flange machining with turningalong the external spigot diameter, high per-formance, multi-bladed PCD bell tools areused. The piston bore is gun bored with PCDstepped tools and finish machined to a highsurface quality with PCD reamers with guidepads. Multi-bladed PCD fine boring tools arebeing increasingly used to achieve higherfeed rates. The lateral connection bores arepre-machined and finish machines in onestep with PCD combination tools.
In the brake system area, main brake cylinders inaluminium alloys are important componentswhich are subject to strict safety conditions. When machining the main brake cylinder housing,quality and production reliability therefore havemaximum priority.

ABS housing
Anti-locking brake systems for carsare now an integral part of theautomobile industry. Electronicallycontrolled braking systems preventthe wheel from locking.
ABS housings are safety relatedcomponents which are subject to acpk analysis. The increasing demandsfor tolerances, burr-free results andan extremely low Si content in thematerial make cutting operations achallenge. In particular extremelyhigh stipulations are made formachining bores in engines andpumps. Decisive factors for success-ful production are surface finish,accuracy, concentricity and inter-relating positions. For bores in pumpsmaximum tolerances of IT 7 with asurface finish of Ra 0.2 µm apply.
Solid carbide tools for pre-machiningtogether with tools with fixed PCDblades and fine boring tools withguide pads are typical tools for thesecomponents.
It was the cutting material PCD whichbrought the MAPAL and WWS compa-nies together. As a specialist in preci-sion machining, MAPAL saw the enor-mous opportunities of the new cuttingmaterial on the one hand but also theextremely high demands on productiontechnology and on the capabilities ofthe workforce when manufacturingtools with PCD (polycrystallinediamond) blades which cannot not beadjusted. An organisation operating inthe jewellery town of Pforzheim in Ger-many seemed to be the right partnerfor the challenge.Werner Stief had first had contact withthis completely new cutting material asfar back as 1978. As he had already hada great deal of experience in machiningdiamonds, PCD aroused his curiosityand he recognised the extent of thetask. When WWS was first establishedin 1980 it could scarcely have beenimagined how PCD tool manufacturingwould develop. This artificially madecutting material came onto the marketat exactly the right time. The amountof aluminium components – particular-ly in the automobile industry – wasincreasing to a disproportionate extentat that time and provided the rightenvironment for using PCD blades. Thefurther development of the machiningtechnology for this cutting materialwas mainly improved and optimised asa result of WWS’s activities.
Brilliant –two partners who complement each other perfectly
The pioneering work by WWS was toenable the eroding method to be usedfor manufacturing PCD blades.MAPAL’s takeover of WWS in 1994provided the initial spark for furtherturbulent development. The increasingacceptance of the HSK connection sys-tem was also helpful and extremelyimportant in the years that followed.The changeover accuracy of within 3 µm which resulted from this has sig-nificant effects on concentricity andthe use of multiple blades and as aconsequence on the life of PCD tools.These are just some of the reasonswhich have contributed to the hugesuccess story of PCD tools.

MAPAL Competence –PCD Tools
A Review of MAPAL’s Competence
Reaming and Fine BoringFrom the wide range of single and twin-bladed reamers with guide pads, together with fineboring tools with guide pads and WP or HX blades, to the HPR High Performance Reamerscombined with the MAPAL HFS® Head Fitting System for exact concentricity and accuratechangeover – to give you a general view of our complete knowledge and experience in pre cision machining bores.
PCD ToolsFor pre-machining and finish machining, MAPAL also offers an extensive programme of pre cision tools with fixed PCD (polycrystalline diamond) blades. This includes precision gunboring tools plus circular and end milling tools. The programme of face milling heads from the PowerMill and EcoMill series is characterised by simple, sturdy design and rapid, accurateblade setting.
ISO ToolsThis aspect of MAPAL competence is made up of special tools with ISO elements for gunboring and milling. This includes precision ground blades in the widest variety of cuttingmaterials and coatings. The use of MAPAL's tried and tested adjustment system ensures thatthe blades are accurately matched to the task. MAPAL offers particular knowledge and ex -perience in tangential technology.
Generating Slide ToolsGenerating slide tools offer a high potential for rationalisation and optimisation on specialmachines and machining centres. In addition to the conventional facing heads, MAPAL alsosupplies EAT and LAT performance-enhanced actuating systems for generating slide tools.MAPAL TOOLTRONIC® tools with their extraordinary range of functions are the latest develop-ment.
DrillingYet another area is the product programme for drilling. MAPAL offers the right tool conceptfor every task, whether for machining aluminium, steel or cast iron, hard machining or drymachining or for use in HSC areas. Specially developed coatings and PCD blades complete the broad-based drilling programme.
Clamping SystemsMAPAL's modern clamping systems, in conjunction with MAPAL's tried and tested reamingand fine boring tools, guarantee maximum productivity and economy. Whether HSK, ISO orHFS®, these high-precision connections and interfaces provide the concentricity and change-over accuracy essential to modern production.
Customer ServicesProject planning, maintenance, management and optimisation – the complete CTS® servicepackage from MAPAL will accompany you from process design to permanent process optimi-sation and will ensure optimum and cost-saving use of your tools with the best possibleresults.
