Haas Automation CNC Horizontal Machining Center HS-7R

Replace coolant and thoroughly clean the coolant tank

Check all hoses and lubrication lines for cracking

Check the rotary A-axis. If necessary add oil (Mobil SHC-630). The correct oil level is halfway on the sight glass

Lubricate the following parts using red grease

Lubricate the Arm Shaft using Moly grease

• Replace air filter on control box every 2 years.

• EC-400 Replace the Rotary A-axis oil

1. Remove the fourteen (14) BHCS on the right Z-axis way cover at the receiver end and slide it toward the column.

2. Remove the left Z-axis way cover: Jog the Z-axis all the way toward the column and rotate the H-frame 45° counter clockwise. Remove the thirteen (13) BHCS that fasten the waycover to the receiver and remove it through the door at the control pendant.

3. Disconnect the reservoir at the rotary indexer end and plug the end of the hose.

4. Remove the drain plug on the opposite side of the rotary indexer. Replug the hole when the oil has drained.

5. Remove the air escape hole plug on the side of the platter.

6. Fill the rotary table until oil begins to escape from the air escape hole and plug it.

7. Replace the reservoir hose and the way covers. Command the receiver 180° to 0° repeatedly for fifteen minutes.

Check way lube lubrication tank level

Clean chips from way covers and bottom pan

Wipe spindle taper with a clean cloth rag and apply light oil

Sign off on the daily CNC horizontal machining center maintenance

Warning: This maintenance check requires trained personnel with PPE!

Check the dirt indicator on the 100-micron mesh filter with the TSC system running and no tool in the spindle. Is it in the red zone?

If the dirt indicator is in the red zone, change the element.

Clean the pump intake filter when indicator is in the red zone. Is it clean now?

After changing or cleaning filter elements, run TSC system with no tool in spindle for at least one minute to prime system.

Warning: Use of coolants with extremely low lubricity can damage the TSC coolant tip and pump.

Warning: Shortened pump life, reduction of pressure and increased maintenance are normal and to be expected in abrasive environments and are not covered by warranty.

Warning: Machining of ceramics and the like voids all warranty claims for wear and is done entirely at customer's risk.

The tool pot chain tension should be checked regulary as a preventative maintenance procedure. Chain tension adjustment is performed in the lower left area of the magazine. Loosen the four 12x50 SHCS from the front of the magazine.

This will allow the plate to move. Loosen the hex lock nut on the shaft and tighten the shaft using the hex bolt. Lock in the adjustment with the hex lock nut, and retighten the four 12x50 SHCS. Tensioning will not change the indexed pot location, but check the alignment between the manual tool push cylinder and the tool pot.;
