High Precision Horizontal Machining Center

Presenting the ideal machining center.It’s been 50 years since the birth of the machining center. As performance reaches

maturity, we at Mori Seiki decided to wipe the slate clean and take a completely fresh

look at machine tool design. The result was “Driven at the Center of Gravity,” a

method to minimize the vibration of moving parts. The perfect “Driven at the Center

of Gravity” system was made possible for the NH4000 DCG by achieving the ideal

form of the machining center. It fuses high speed and high quality at a top level.

However, the machining center still has room to grow. This is proven by how much of

the future is packed into this machine.

DCGTM: Driven at the Center of Gravity

1: A breakthrough in high-speed, high-precisionmachining technology after 15 years.

Starting in the mid-1980s, machine after machine was producedfor high speed and high precision. The biggest challenges duringthe first 10 years were size and speed and spindle motors,developing the technology to deal with the resultant heat,designing machines to match fast NC devices, and other areas.The results were quite impressive. However, the past 5 yearshave seen a loss of direction in the search for technologies toincrease speed and precision. Machining time was only slightlyreduced by increasing speed, but on the other hand speed hadto be sacrificed for higher precision or surface quality.

In comes “Driven at the Center of Gravity” – a technologycreated by approaching the actual movement dynamics of themachine. Any machine tool engineer worth his salt knows it’salways better to push against the center of gravity. Few engineersthought about why this is so important.

At Mori Seiki, we believe this technology will make possiblethe most fundamental improvements in machining time, precision,surface quality, and tool life. This principle is common to allmachine tools in which the tool and the workpiece move relativelyto each other, not just machining centers.

Mori Seiki machines using the “Driven at the Center of Gravity”principle can move as instructed, accurately and with ease.

2: Driven at the Center of Gravity

The “Driven at the Center of Gravity” principle reducesmachining time, improves contouring precision, and deliversbetter surface quality. Everyone knows you have to pushsomething at its center of gravity; otherwise it will spin andbecome unstable. “So push it at the center” – that, in so manywords, is the “Driven at the Center of Gravity” principle. (Fig. 1)

Machine tools use ball screws and linear motors to movetools and workpieces. If they are pushed at their center ofgravity, moving them poses no problem, although, sometimesthis is not true.

Why? Take, for example, the axis that moves the spindle upand down in a vertical machining center. The center of gravityof the spindle is the center of the spindle itself, but you cannotput a ball screw there.

On the other hand, the center of gravity of the axis whichmoves the table back and forth in a horizontal machining centeris somewhere just above the surface of the table when workingwith a heavy workpiece. In other words, the table’s center ofgravity is inside the workpiece. There is no way you can get aball screw in there, either.

The solution? At Mori Seiki, we had the idea to enclose thecenter of gravity with two drive points on either side. The lineconnecting the middle of two ball screws would have to passthrough the center of gravity of the object being moved. (Fig. 2)

[The “Driven at the Center of Gravity” principle]

If the edge of the part is beingpushed, balance is lost andvibration is created.

If the center of gravity ispushed, the part moves straightwithout any vibration.

Machine tools hold objectsabove the center of gravity,making it impossible to pushthem at the center of gravity.

However, if the edges on otherside of the center of gravity arepushed, the object movesstraight.

(Fig. 1) (Fig. 2)

3: Vibration during axis travel

So what, specifically, are the advantages of the “Driven at theCenter of Gravity” innovation? In a word (or two): less vibration.The graph (Fig. 3) compares vibration in our “Driven at theCenter of Gravity” machines and standard machines.■ shows the amount of vibration during travel in the

NV4000 DCG without the “Driven at the Center of Gravity”principle applied. ■ shows the same situation, but with theprinciple applied. The results are dramatic and clear.

4: What’s so bad about vibration?

This graph (Fig. 4) shows a time-based representation ofvibration. Note how the “Driven at the Center of Gravity”machine stops the vibration almost right away, while the ordinarymachine continues to vibrate long after.

At the edge of the vibrating machine, a tool and a workpieceare attached. Obviously, the vibration will adversely affect thequality of the machined surface.

Additionally, if the tool enters the workpiece while both arevibrating, the tool tip will wear down. Vibration is the naturalenemy of tool life.

There is an even graver problem. When there is vibration,the NC device reacts to it by deviating from the instructionsand attempts to correct it by moving the feed motor. This, ofcourse, results in even more vibration in most cases.

Engineers are familiar with this phenomenon, so to counteractit, they adjust the NC device to react with less sensitivity. Inother words, they make the NC device ignore minor discrepancies.As a result, operating precision plummets or speed is sacrificed.Therefore, vibration could be called the natural enemy of precision and machining time.

The vibration occurring after the spindle is raised and lowered, then stopped.

5: Why linear motors?

Linear motors are touted as the end-all be-all when discussingdynamic characteristics of machine tools, supposedly because theball screw acts as a torsion bar. Is this really the case when com-pared with the “Driven at the Center of Gravity” principle? Thegraph (Fig. 5) adds a linear motor to the previous graph (Fig. 3).■ is a non-“Driven at the Center of Gravity” machine with

a linear motor and ■ is a “Driven at the Center of Gravity”machine with a linear motor. The effects of the linear motorare negligible compared with those of the “Driven at the Centerof Gravity” design.

7: Reduction of machining time

The “Driven at the Center of Gravity” innovation is veryuseful for reducing machining time.

Machines that are “Driven at the Center of Gravity” producelittle vibration at the start of acceleration, which means theycan accelerate at full force right from the start. Machinesnot endowed with this innovative technology, however,must apply accelerating force gradually, for fear of creatingtoo much vibration when starting to accelerate.

This graph (Fig. 7) shows non-“Driven at the Center ofGravity” machines on top and “Driven at the Center ofGravity” machines on bottom. It clearly shows the differencein time to maximum acceleration when starting to accelerate,indicated by the blue curve, creates a very large gap in thetime it takes to reach maximum speed.

8: Gain

Is the “Driven at the Center of Gravity” innovation necessaryon all axes? The point of using “Driven at the Center ofGravity” technology is to reduce the amount vibration causedwhen an axis begins moving. This vibration is caused whenthe location being pushed and the center of gravity of theobject being moved are not the same. If the difference isminor, then this innovative technology is not needed.That’s where gain comes into play, so let’s take a closer look.

Gain is a parameter used to control the accuracy of amachine’s movement. The greater the gain, the more amachine tries to move accurately in accordance with itscontrol instructions. Some machines cannot follow thoseinstructions faithfully, causing a great deal of variation inthe movement.

Machine designers know you can set the gain high on agood machine but cannot on a bad machine, so they try tofind ways to raise the gain. The size of the gain can varywithin the same machine, depending on the axis involved.Some axes can handle high gain, and some cannot. AtMori Seiki, we think this depends on the distance betweenthe center of gravity and the drive point.

Therefore, it is not unreasonable to say there is little needto add ball screws or use careful axis-center drive on axeswhen distance is short and gain can be set high.

6: Improving machined surface quality

The “Driven at the Center of Gravity” design is said to be effectivein improving machined surface quality. Let’s examine this claim.

Machining of curved surfaces is a major part of die and moldmachining. The curved surface can be looked at as a successionof subtle polygonal lines – the direction of travel changes ever soslightly at each corner along the line. In order to make thesechanges without losing speed, powerful acceleration is needed,even if the changes in direction are only slight.

At each point where acceleration starts, rotational vibration pro-portional to the distance between the drive point and the center ofgravity occurs. This is particularly noticeable when the machiningpoint descends down the side of a pocket, reaches the bottom, andthen suddenly changes direction. The unstable lines in Picture aretraces of a sudden change in direction by the machining point inan ordinary machine.

However, the “Driven at the Center of Gravity” technology getsto the heart of the cause of deterioration in the quality of themachined surface.

Another example of this type of sudden change in direction is thecutback during round cutting. This problem occurs when the toolcuts into the workpiece at 0°, 90°, 180°, and 270°. Roundness isvery important when replacing boring with contouring using anend-mill that easily makes diameter correction. The “Driven at theCenter of Gravity” technology improves roundness, too.

MaintenanceMaintenance has beenmade extremely easy.MTTR is an index that rates how easy it is to maintain a

machine. The NH4000 DCG is extremely easy to maintain, since

there are design concepts incorporated throughout the

machine to make maintenance easy and quick-important

factors in reducing downtime.

Ceiling tilt

Adjustable operating panel

90˚90˚

A tilted ceiling preventscoolant from drippingonto the operator.

Swinging the operation panel reduces eye strain and improves operability.

OperabilityThorough convenience.The NH4000 DCG has been designed with the operator in mind, as seen by the

labor-saving features throughout the machine.

Magazine

Visibility of the magazine has been improved with the addition of a door with a window.

An oil-bath design hasbeen integrated into theATC unit. Comparedwith conventional oildrip designs, theamount of lubricantused is radically less.

Eco-friendly designA variety of functions reduce the environmental burden.Reducing the strain on the environment has become an important task

facing companies today. The NH4000 DCG has been designed with

environmentally friendly functions to make this task easier. The new

functions focus on reducing lubricant and electricity consumption. This

focus fills customer needs at reduced costs.

Oil-free roller guides A lubricating oil system for the roller guide is installed on both ends of the block.

● Automatic power-off functionIf the keyboard is not touched after a certainamount of time and NC operation is not beingperformed, power is cut off to the servomotor,the spindle, the coolant pump, and the chipconveyor, thereby saving energy.

Lubricant consumption per hour

Previous model24mL/hour

NH4000 DCG 1.67 mL/hour

Energy-saving settings screen

● Automatic machine light functionIf the operating panel is not touched for a certain amount of time, the interior light turns off.This saves energy and lengthens the life of the machine lights.

● Low speed/low acceleration control functionThis function limits the speed and acceleration of the feed axes when manual operations are carried outduring setup with the interlocks released. By adding a restriction on acceleration to the speed restriction,an even greater power saving is achieved.

Reduced consumption of lubricant
