2.5 Extended Liner System - Installation

Remove the side panel [1] next to the coolant collector. 

Important: If a bar feeder is currently installed on the machine it will need to removed and reinstalled after this procedure. Refer to Haas Bar Feeder - Installation - NGC for more details.

Use the bolts [1] to adjust the stand so that it sits about 2.125 in (54 mm) [2] off the floor on the bolts.

Once the feet [3] are added, the stand should be about 47 in tall (1194 mm) [4] and perpendicular to the floor.

Note: Use a bubble level to ensure the stands base and back are leveled. 

Remove the angled panel [1] on the stand.

Position the stand so that it is sitting between 12.125 - 12.25 in (308 - 311 mm) [1] from the side of the machine and in line with the coolant collector's center. 

The stand should be 0.200 - 0.250 in (5 - 6 mm) [2] from the coolant collector to allow room for adjustment. 

Adjust the stand until the circular opening is visually concentric [3] with the piston and spindle. 

Lock spindle and install the extended liner adaptor [1] through the stands opening onto the piston threads [2] hand tight.

Unlock spindle and measure the runout of the end of the extended liner adaptor and mark the high spot [1].  

Note: Use the closer to rotate the extended liner adaptor.

Position the extended liner adaptors high spot [1] to point up.

Grease the inside [2] of the housing then install housing over the extended liner adaptor and hand tighten the screws [3] in a star pattern. 

Note: Make sure the screws have full clearance of the through holes. If needed, reposition the stand until there is full clearance. 

Align the base of the anchor [1] with the centerline of the bolts [3] then move it towards the stand until it touches the puck [2].

Mark the far end of the slot with a marker [1] then remove anchor assembly and repeat for all 4 corners.

Once all corners are marked anchor machine based off Anchoring Instructions. 

Important: Leave the anchors loose to allow movement for alignment.

Anchors should be installed in this orientation before alignment.

Drop the chuck pressure to 180 psi [1].

Snug the bolts [1] on the housing down to make the stand perpendicular to the extended liner adaptor, tap the sides of the stand to help align it.

 Note: The back of the stand needs to be perpendicular to the Z-axis. Check for gaps between the housing and the stand, adjust until the housing is flush with the stand all the way around.

Torque housing bolts [1] to 15 ft lbs. in a star pattern.

Bottom out bolts and stop when they make full contact with the pads. 

Torque the 4 anchor nuts [1] to 25 ft lbs.

Once all bolts and nuts from the previous steps have been tightened or torqued, actuate the chuck to check for binding.

 If there is binding, determine bind direction. Lightly push and pull on stand in Z axis direction to listen for the binding sound to decrease. Based on this direction, adjust both back 2 bolts [2] to 1/8 of turn increments or less.

 Note: Repeating steps 2-7 may be necessary if binding does not improve after implementing this step. 

If no binding occurs, evenly snug nuts (4) [1] and give them an 1/8^th of a turn.

Reinstall the angled panel [2] on the stand.

Once all the bolts are tightened down and there is no binding when actuating, change setting 282 to I.D. [1].

Press [SETTING], type in 282, and press [F1] to search for setting 282. Change the value in setting 282 to I.D.

Use spanner wrench [2] to tighten extended liner adaptor [3].

Tighten the collar set screws [4] in a star pattern. The collar should be fully pressed up against the extended liner adaptors shoulder. 

Change setting 282 back to O.D.

Check the runout of the end of the extended liner adaptor, NTE 0.0030".

Install the retaining clip [1], coolant collector extender [2], and access cover [3].

Note: The coolant collector extender has a hose that needs to be fed through the stand and coolant collector. 

Reinstall the side panel next to the coolant collector. 

Bar Feeders should be placed between 24.125 - 24.375 in (613 - 619 mm) [1] from the side of the lathe and 0.125 in (3 mm) [2] from the access cover handle [3]. 

To install a Bar Feeder, follow HAAS BAR FEEDER - INSTALLATION

Before anchoring the Bar Feeder down, verify it clears the access cover handle [3]. 

Turn on the machine.

Login to the HBC PORTAL.

Download the Extended Liner System option configuration patch files.

 Note: The option files will appear on the configuration download page after the Extended Liner System service kit has been ordered. If the option does not appear, contact the service department.

Load the option configuration patch file to the control. Refer to the NEXT GENERATION CONTROL - CONFIGURATION FILE - DOWNLOAD/LOAD procedure. 

The extended liner system decal location [1]. 

The decal [2] illustrates the following specifics:

• Bar Straightness - This aids in minimizing vibration and preventing the potential of jamming bars within the spindle.
• Chamfering - This process serves to avert both jamming and the possibility of marring the liners.
•  Maximum RPM - This consideration is crucial in order to effectively diminish vibration.
• Procedure for Removing the Retaining Clip - Prevent the loss of the clip during removal. To achieve this, it is recommended to press down on the clip with a finger to counteract it from springing out.
