Anchoring Instructions

AD0212

Applies to machines built from: July, 2009

IntroductionAnchoring:

• Increases the "apparent" mass of the machine.• Improves dissipation of machine vibrations into the foundation.• Improves overall stability and can reduce re-leveling requirements.• Prevents axis acceleration from moving the machine.• Keeps the machine aligned with accessory components (Bar Feeder, Pallet Pool / Changer).• May be required for certain machine models (DT/DM, EC-1600) or accessories like the Haas Bar Feeder.

Limitations of anchoring:

• Anchoring requires drilling into the foundation.• Anchoring makes the machine installation process more expensive.• Anchoring requires a proper foundation and properly set anchors.• Anchoring makes it more difficult to move a machine to a different location.

An alternative to anchoring:

Most Haas machines now include cold-flow anchoring pads in place of the traditional leveling pads. These pads havea "cold-flow" material built into the bottom of each pad, which helps to improve the machine's connection to itsfoundation. The "cold-flow" material uses the machine's own weight to form an intimate connection between thebottom of the pad and the foundation's surface. This has several benefits:

• Cold-flow anchoring pads elminate the need for traditional machine anchoring, in most cases.• Cold-flow anchoring pads reduce the cost of machine installation.• Cold-flow anchoring pads make it much easier to move the machine to a new location.

Prerequisites

Caution: You must install the anchors before your HFO delivers your machine. Give these instructions to theperson in your shop who is responsible for machine installations. Contact Haas Automation Service at (805) 278-8500if you have questions. Have the machine serial number available.

Read these instructions fully before you install the anchors.

Anchoring is not required for proper performance of Haas machines. The anchor kits are not intended to satisfybuilding, seismic or stationary equipment installation requirements. Consult an expert for help with theserequirements.

The anchor kits include only the hardware to assemble the anchors. The anchor kits do not include the epoxynecessary to set the anchors. Use epoxy with at least 16000 psi (1103.4 bar) compression and 4000 psi (275.86 bar)tensile strength. For example, you can use Chockfast Gray. Chockfast Gray is available from ITW Resins. Referto WWW.CHOCKFASTGROUT.COM to find a local distributor.

Foundation Requirements

Refer to the Pre-Installation Information at HAASCNC.COM/PREINSTALLATION for details on machine foundationrequirements.

Machine Placement

Refer to the Pre-Installation Information at HAASCNC.COM/PREINSTALLATION for details on machine placement.

Make sure sufficient space to install the coolant tank is around the machine before you drill the anchor holes. Goto WWW.HAASCNC.COM for the Machine Layout Drawing. Find the Machine Layout Drawing in the "Dimensions" linkon the page for each machine model. Refer to the Machine Layout Drawing for anchor hole locations and machineillustrations. Contact your Haas Factory Outlet to get the correct anchor kit.

Drill Holes and Prepare the AnchorsBefore you drill, go to WWW.HAASCNC.COM for the correct anchor hole locations and machine illustration. Find theMachine Layout Drawing in the "Dimensions" link on the page for each model.

On a 6" (150 mm) concrete slab, drilled holes must be 1.5" (38 mm) diameter and a depth of 6" (150 mm), (Standardfoundation requirement).

On a 12" (300 mm) concrete slab, drilled holes must be 1.5" (38 mm) diameter and a depth of 8.5" (215 mm), (EC-1600machine foundation requirement).

Caution: Completely clean and dry the drilled holes. Make sure no oil or water is in the drilled holes. If you cleanand dry the drilled holes with air, make sure the air has no oil or water.

1Put the coupler nut [1] onto the 5/8-11 bolt [2].Turn the coupler nut until the bolt is half thedistance into the coupler nut.

Turn the 5/8-11 hex nut [3] on to the long threadside of the stud halfway [4].

2Put the floor plate [1] and the 5/8 washer [2] onthe long end [3] of the stud below the 5/8-11 hexnut [4].

Put the long end [5] of the stud into the couplernut [6] until it stops.

Tighten the 5/8-11 hex nut [7] with your fingers.Make sure the floor plate [8] and washer [9] aretight against the coupler nut [10].

Set the Anchors

1Mix the epoxy. Refer to the epoxy manufacturer’sinstructions.

Fill the hole until the epoxy is approximately2" (50 mm) [2] from the top of the hole [1].

Caution: Make sure you do not put too muchepoxy into the drilled hole. If you put in toomuch, the epoxy level will rise too high when youput the anchor assembly into the hole.

2 Note: Be prepared to do this step quickly,before the epoxy becomes hard.

Do these steps to make sure the quantity ofepoxy is correct.

• Push the anchor assembly into the holeuntil the floor plate is against the floor.

• Pull the anchor assembly far enoughout of the hole to see where the epoxyreaches on the coupler nut. If thequantity is correct, the epoxy stops atthe approximate middle [1] of thecoupler nut.

Caution: Make sure that there is not too muchepoxy in the hole. Excessive epoxy will go overthe top of the coupler nut [2]. This prevents theremoval of the stud later in this procedure.

Put the anchor assembly into the hole. Make surethe stud [3] points up.

Make sure the stud is perpendicular to the floor.Use a carpenter's square [4].

Refer to the epoxy manufacturer’s instructionsfor the time to cure. The time to fully cure istypically 18-24 hours.

Tell your HFO that you have completed this task.

1 Note: The following should be done byauthorized personnel. The service technicians atyour Haas Factory Outlet (HFO) have the training,expirience, and are certified to do these taskssafely and correctly.

After the epoxy fully cures, remove the studs [1].

Remove these parts from each stud:

• the floor plate [2]• the washer [3]• the 5/8-11 hex nut [4]

Move the machine into position near the couplernuts [5].

2Put the side of the stud [1] that has the shorterthreads into the coupler nut [2] in the floor. Makesure that the machine base casting does nottouch the stud. Put the stud into the coupler nutuntil it cannot go in farther.

Move the floor plate [3] down the stud until it isflat on the floor.

3Put the 3/4-10 hex nut [1] on the 3/4-10 x 6 bolt[2]. Turn the nut [1] until it is 2" (50 mm) from thetop of the bolt.

Put the 3/4-10 x 6 bolt [3] head-down on the floorplate. Put the bolt in a position that aligns withthe anchor strap for the next step.

4Put the anchor strap [1] on the bolt and stud.

Put the 5/8 washer [2] on the stud.

Put the 5/8-11 hex nut [3] on the stud.

Loosen the anchor assembly before you makethe machine level.

Torque the Anchors

1 Note: The anchors must be completly loose when leveling the machine.

Make sure the machine is level.

After the machine is correctly level, torque the 5/8-11 hex nuts on the studs to 30 ft-lb (41 Nm) in the sequenceapplicable to that machine.

Make sure you torque the anchor nuts in the correct sequence. Refer to the table that follows. The machine front islabeled as [A].

Torque Sequence

2Torque the 5/8-11 hex nuts on the studs to 50 ft-lb (67.8 Nm) in the same sequence as step 1.

Torque the 5/8-11 hex nuts on the studs to 80 ft-lb (109 Nm) in the same sequence as step 1.

Make sure the machine is level after you torquethe anchors.
