Preserving a machine that only recieves Limited Usage

Scope:

The following recommendations are for a machine that will be kept in use at a reduced frequency of operation (approximately once per month).

 

ONCE A WEEK THE FOLLOWING PROCEDURE MUST BE FOLLOWED.

TURN OFF THE MACHINE'S ELECTRICAL POWER WHILE CLEANING TO ASSURE THAT THE MACHINE CANNOT ACCIDENTALLY MOVE DURING THE CLEANING PROCESS. UNEXPECTED MACHINE MOTION COULD CAUSE MACHINE DAMAGE OR PERSONNEL INJURY OR DEATH.

TURN OFF THE MACHINE'S ELECTRICAL POWER WHILE CLEANING TO ASSURE THAT THERE IS NO CHANCE OF AN ELECTRICAL SHOCK HAZARD. AN ELECTRICAL SHOCK COULD CAUSE OR PERSONNEL INJURY OR DEATH.

 

  1. Thoroughly clean the machine of any accumulation of chips and cutting coolant.

    A: Brush off any large accumulation of chips from the machine and any way covers that the machine may have.

    B: CAUTION: Clean ONLY by wiping or brushing. Do NOT use compressed air as this tends to force the dirt into the working parts of the machine. Way areas, way covers, feedback devices and the spindle nose and spindle sleeve are particularly vulnerable to damage through the use of air hoses for cleaning.

    C: Wipe off any cutting coolant or liquid from the machine. Clean ONLY by wiping. Special care should be given to ALL exposed metal surfaces. electrical enclosures, electrical devices, motors and the operator control stations.

     
  2. Run the spindle in and out (under power) four (4) or five (5) times to coat the spindle surface with an oil film. If an insufficient film results - HAND APPLY oil.

     
  3. Run the Head, Table and Saddle their full travels (under power) two (2) or (3) times while manually cycling the way and gib centralized oiling system to coat the INTERNAL portions of the slideway system with oil.

     
  4. Coat the Column ways, Bed ways, Saddle ways, the front of the Head, the Spindle and the Spindle Sleeve, all feed screws and ALL other exposed metal surfaces with oil.

     
  5. Check that the self-dumping water filter on the incoming air line is operating and that there is no accumulation of water in the bowl. Also check that air pressure is being maintained at 80 PSI.

     
  6. The sir line lubricator bowl should be full of oil to the appropriate level mark. Inspect the oil in the bowl for signs of contamination or 'breakdown'. If the oil is contaminated or is sedimenting, drain off the old oil and install new oil.

     
  7. The air pressure settings (when applicable) to the centralized way and gib lubrication system should be verified to be set to the correct settings as defined in the maintenance manual. If found to be incorrect, it should be set properly.

     
  8. Check the oil level in the reservoir of the centralized way and gib lubrication system. Fill with proper oil as required.

     
  9. Consult the machine's maintenance manual for any specific additional operations that should be performed. Many maintenance manuals include a section dealing with standard preventative maintenance procedures. Those procedures should be performed at the recommended frequency IN ADDITION to the items included in this listing.
