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 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: 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.

Warning: 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.

Oil level in the reservoir is adequate

Drain plug removed from the left side of the rotary indexer

Air vent plug removed from the upper right of the drain hole

Rotary indexer filled at the oil fill hole

180° to 0° rotation command executed for fifteen minutes

Oil level is half way on the site glass

• Check Through the Spindle Coolant (TSC) filters. Clean or replace element if needed.

• Check for proper operation of auto drain on filter regulator.

• On machines with the TSC option, clean the chip basket on the coolant tank.

Remove the tank cover and remove any sediment inside the tank. Disconnect the coolant pump from the cabinet and power off the machine before working on the coolant tank.

Do this MONTHLY for machines without the TSC option.

• Check air gauge/regulator for 85 psi. Check the spindle air pressure regulator for 17 psi. For 15K-spindle machines, check spindle air pressure regulator for 20 psi.

• For machines with the TSC option, place a dab of grease on the V-flange of tools.

Do this MONTHLY for machines without the TSC option.

• Clean exterior surfaces with mild cleaner. DO NOT use solvents.

Remove the sheet metal necessary to gain access to the transmission. View the sight glass on the side of the transmission box as shown. The oil level should be half way on the sight glass. Fill as needed.

1. Remove the sheet metal from the spindle head.

2. Remove the drain plug as shown. Inspect the magnetic drainplug for signs of metal particles.

3. Blow downward with an air hose in the vicinity of the fill hole to prevent dirt and metal particles from entering the gear case. Remove the fill plug.

4. Add Mobil DTE-25 gear oil until the oil level is half way up the sightglass.

5. Run a spindle warm-up and check for leaks.;
