Haas Automation CNC Horizontal Machining Center HS-4R

The TSC pump is a precision gear pump and will wear out faster and lose pressure if abrasive particles are present in the coolant.

• Check the dirt indicator on the 100-micron mesh filter with the TSC system running and no tool in the spindle. Change the element when the indicator reaches the zred zone.

• Clean the pump intake filter when indicator is in the red zone. Reset indicator with button. All intake filters can be cleaned with a wire brush.

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

• Coolant will be used more quickly when the TSC system is in use. Make sure to keep the coolant level up and to check the level more frequently (check after every eight hour shift). Premature wear of the pump can result from running with a low coolant level in the tank.

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

Shortened pump life, reduction of pressure and increased maintenance are normal and to be expected in abrasive environments and are not covered by warranty. A special filter, in addition to the standard filter should be used; contact Haas for recommendations.

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

• Replace the gearbox oil. Drain the oil from the bottom of the gearbox.

Remove inspection cover beneath spindle head. Add oil slowly from top until oil begins dripping from overflow tube at bottom of sump tank. For 50 taper spindles, add oil from the side of the transmission.

• Check oil filter and clean out residue at bottom of filter.

• Check SMTC oil level in sight glass, (see Side Mount Tool Changer Oil Level in this section).

• Lubricate the Changer Slide Linear Guide with red 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 oil level in gear box. For 40 taper spindles: Remove inspection cover beneath spindle head. Add oil slowly from top until oil begins dripping from overflow tube at bottom of sump tank. For 50 taper spindles: Check oil level in sight glass. Add from side of gearbox if necessary.

• Inspect way covers for proper operation and lubricate with light oil, if necessary.

• Place a dab of grease on the outside edge of the guide rails of the tool changer and run through all tools.

• EC-400 Clean the locating pads on the A-axis and the load station. This requires removing the pallet;

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
