Haas Axis Lubrication Oil - Conversion

Introduction

Important: CHC Mills will need software M18.28 or higher and CHC Lathes will need software L11.24 or higher.
Service Techs performing the software update on CHC Mills should view this service news on the HSG site.

Note: If your machine needs to upgrade to a metal reservoir from plastic, order kit 93-2601B and refer to the HLG Plastic to Metal Haas Axis Lube Oil (HALO) Reservoir - Conversion procedure.

This procedure will explain how to convert the axis lubrication system to Haas Axis Lubrication Oil on machines with Haas Liquid Grease.

Axis Lubrication Has Changed From Grease to Oil - Service Update

This procedure applies to the following service kits:

93-3585: AXIS LUBE CONVERSION KIT HLG TO OIL
93-3610: HALO SVC KIT CHECK VALVE

Note: Every Lathe will need at least one (1) of kit 93-3610. Lathes that also have a Y-Axis will need to order two (2) of kit 93-3610.

Note: UMC's will now need three (3) of kit 93-3610 to add check valves to all of the lubrication lines.

Important: Before ordering any check valves kits (93-3610) please verify the machines configuration in the images in the Install New Reservoir section below.

Before performing this procedure, verify the axis lubrication system is clear. This can be verified by running an Axis Lubrication Test in the Maintenance Tab. If Alarm 2082 is generated OR if the pressure has not gone back down in 1 hour, this is an indication that the axis lube lines are clogged.

If you need to purge axis lube lines refer to the following procedure: Haas Liquid Grease - Purge Clogged Lines.
NOTE: If the machine has a C-axis, the C-axis gear lube hose must be disconnected from the lube panel manifold during the lubrication air purge process.

Once the lines have been purged and the pump manifold cleaned, continue on to the rest of this procedure.

Install New Reservoir

1

Fill the new reservoir [1] with the Haas Axis Lubrication Oil to about 1/2" (13 mm) below the threads on the reservoir.

2

Follow this step for Mills

Note: UMC's will now need three (3) of kit 93-3610 to add check valves to all of the lubrication lines, the check valves are grey in image [2] to show where they need to be added.

Mills with a SMTC will need to add a .02" orifice (shown as the red component in the images) to their lube lines on the oil reservoir. Use the numbered images and the following list to see where the orifice needs to be added on the following machines:

SMTC: VF - 1-9, DT, DM, VR-8, VM - 2/3/6, VC-400
UMC 350-1600
EC-400/500/500-50T/630/630-50T
GM-2, GM-2-5AX
VF - 10/11/12/13/14, VR - 9/10/11/12/13/14
VMT-750
VS-1/3

Note: A small amount of SMTC's do not have a servo carousel and therefore will not need the additional orifice. This means that any mills that only have 3 grease lines on the lubrication reservoir do not need the additional orifice.

Note: Not all lubrication configurations are shown, only configurations that are adding new fittings in the conversion process are shown for reference on where the new fitting goes.

3

Follow this step for Lathes

Note: Every Lathe will need at least one (1) of kit 93-3610. Lathes that also have a Y-Axis will need to order two (2) of kit 93-3610.

Note: Tail stock fittings are shown as the blue component in the images.

Lathes with a C-Axis will need to add a .02" orifice (shown as the red component in the images) to their lube lines on the oil reservoir. Lathes will also need to add an extra check valve and nipple fitting to the X-Axis and the Y-Axis if it has one (the X and Y axes are labeled in the image to the right). Use the numbered images and the following list to see where the orifice and fittings need to be added on the following machines:

8. Longbed & Non-longbed: CL, ST-10/15/20/25/28/30/35

9. Y-Axis Longbed & Non-longbed: ST-10Y/ 15Y/20Y/25Y/28Y/30Y/35Y, ST-10LY/15LY/20LY/25LY/28LY/30LY/35LY

10. C-Axis Longbed & Non-longbed: ST-10/ 15/20/25/28/30/35

11. C-Axis & Y-Axis Longbed & Non-longbed: ST-10Y/ 15Y/20Y/25Y/30Y/35Y

12. Longbed & C-Axis & Y-Axis & Sub-Spindle: DS-30Y, ST-10LY/ 15LY/20LY/25LY/28LY/30LY/35LY

13. Longbed & Tail Stock: ST-40/40L/45/45L/50/55

14. Longbed & C-Axis & Tail Stock: ST-40/45/50/55

15. Longbed/Non-Longbed & Tail Stock: ST-30/35

16. Longbed/Non-Longbed & Tail Stock & Y-Axis: ST-30Y/35Y

Note: Not all lubrication configurations are shown, only configurations that are adding new fittings in the conversion process are shown for reference on where the new fitting goes.

Axis Lubrication System - Verification

1

For NGC machines:

Change Setting 277 to 3 hours [1].

Note: Contact your HFO to download and apply the latest patch from the HBC site on their next visit.

For CHC machines:

Set Parameter 1401 to 12 hours and Setting 252 to 3 hours.

2

For NGC machines:

Press [DIAGNOSTICS].

Go to the Maintenance tab and navigate to the Lube tab.

Press [F2] to start the Axis Lubrication Test.

For CHC machines:

Press [PARAMETER DIAGNOSTIC] (2) times to show the diagnostics page.

Press [CANCEL].

Go to the LUBE tab.

Press [WRITE/ENTER].

Press [F2] to start the Axis-Lubrication Test.

3

Perform the Axis Lubrication Test again until you no longer get axis lubrication alarms. Wait a minimum of (1) minute between Axis Lubrication Test cycles.

Check the level of the oil in the reservoir.

If the oil lines were nearly empty, it may be necessary to refill the axis lubrication reservoir after you purge the lines of air. Pour the oil into the reservoir to about 1/2" (13 mm) below the threads on the reservoir.
