Every Three Months or 500 Hours

  • Check and grease the chain on the chip conveyor
  • Check and clean the filters on the coolant tank

Every Six Months or 1000 Hours

  • Have the coolant tank cleaned of sludge, chips, and oil
  • Have the chuck and jaws taken off the machine and cleaned
  • Have the hydraulic tank drained and replace the hydraulic oil with fresh hydraulic oil also have the line filter and suction filter changed
  • Have the radiator cleaned and make sure the radiator fins are straight
  • Have the lubrication unit drained and cleaned out – then add fresh way lube
    If your machine is equipped with a cooling unit, have the unit drained and refilled
  • Have the leveling of your machine checked and adjust if necessary
  • Have all way wipers inspected for any damage – clean and replace any wipers that are damaged

Once a Year or Every 2000 Hours

  • Have the headstock checked for taper
  • Have the spindle checked for radial and end play
  • Have the chuck cylinder checked for run out
  • Have the tailstock checked for taper
  • Have the turret parallelism and inclination checked
  • Run a backlash program to check the backlash in X and Z axis and adjust if necessary
  • Check the X and Z axis gibs and adjust if necessary
