Milltronics Manufacturing Company Lathe ML-30

Check operation of all cooling fans.

Clean any chips from around the tool turret.

Add a few drops of way lube to the tailstock as shown in figure to right.

Inspect the coolant collector at the rear of the spindle to ensure it is draining properly and is not blocked by chips.

If cutting chips accumulate in the collector, install a plug in the spindle/chuck bore to prevent this.

If machine is equipped with a hydraulic chuck and the drawtube bore is not being used, install the chuck plug supplied in order to stop fine chips from working their way into the coolant collector screen.

If the coolant collector overflows, coolant may be allowed to contaminate the hydraulic oil.

Apply a few pumps of general-purpose synthetic grease to each grease zerk on the chuck itself.

Initial Checks of the Machine, its Guards and Safety Systems

1. Check for missing parts. Do not operate the machine if parts are missing.

2. Visually check for damage outside of machine and inside. Do not operate the machine if there has been shipping damage.

3. Check to see that all necessary guards and safety switches are in place. Do not operate the machine if necessary guards and safety switches are not in place.

Failure to observe these rules can result in death or serious injury.

• Arc flash and shock hazard. Follow ALL requirements in NFPA 70E for safe work practices and for Personal Protective Equipment before opening electrical cabinet or performing adjustments or diagnostic measurements while energized.

Warning: This maintenance check requires trained personnel with PPE!

Inspect ballscrews and way surfaces. Adjust gibs if necessary.

Inspect all oil lines, and ensure all ballscrews and way surfaces are receiving oil. Repair or replace oil lines as necessary.

Inspect all belts for excess wear, damage, and proper tension.

Check operation of low air pressure switch (if equipped). Remove compressed air source from the machine and verify that a red alarm message box appears at the front panel display.

DANGER: Arc flash and shock hazard. Follow ALL requirements in NFPA 70E for safe work practices and for Personal Protective Equipment before opening electrical cabinet or performing adjustments or diagnostic measurements while energized. Only qualified personnel should attempt to take current and voltage readings or perform service.

Power down the machine. Open the door to the electrical cabinet at the back of the machine. Check for loose wires or loose components.
