Haas Automation CNC Horizontal Machining Center HS-6

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 the indicator in the red zone?

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

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

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

Is the coolant level up and checked frequently (after every eight hour shift)?

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

Increased maintenance schedules are absolutely required with abrasive swarf. The coolant must be changed more often and the tank thoroughly cleaned of sediment on the bottom. An auxiliary coolant filter is recommended.

When machining castings, sand from the casting process and the abrasive properties of cast aluminum and cast iron will shorten pump life unless a special filter is used in addition to the 100 mesh suction filter.

• 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.

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.;

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

Warning: This procedure requires trained personnel with PPE!

Remove the screws that hold the oil reservoir to the pump body, carefully lower the reservoir and set aside.

Use a strap wrench, pipe wrench or adjustable pliers to unscrew the end cap. Use a screwdriver or similar tool to stop the filter from turning while the end cap is removed.

Remove the oil filter element from the filter body once the end cap is removed.

Clean the inside of the filter housing and the filter end cap as required.

Install the new oil filter element (p/n 94-3059), O-ring and the end cap. Use the same tools that were used to remove the filter end cap, to tighten it - Do Not Over Tighten.

Replace the oil reservoir; ensure the gasket seats properly between the reservoir and the top flange.
