Routine Maintenance

1. Daily Care

On a weekly basis, or every 40 hours, take the filter off the CNC control cabinet and clean it so air will be able to flow through for cooling.
Check the hydraulic pressure to make sure it’s at 4.5 MPa
Check the hydraulic fluids to make sure they’re at the right operating level
Check to make sure the chuck pressure is at the right operating pressure
Make sure the way lube level is at the right operating level, and replenish if needed
If your CNC machine has a cooling system, make sure the cooling unit level is at the right operating level
Clean the chips out of the chip pan, and grease any part that may need to be greased
Clean off the window of the door and the light so you can see inside your machine
Wipe down any stainless steel way covers and lubricate them with hydraulic oil so they move smoothly

2. Quarterly Care

Every three months or 500 hours, contact your local distributor to have the following preventive maintenance performed by a certified Engineer:
Check and grease the chain on the chip conveyor
Check and clean the filters on the coolant tank

3. Semiannual Care

Every six months or 1000 hours, contact your local distributor to have the following preventive maintenance performed by a certified Engineer:
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

4. Annual Care

Every year or 2000 hours, contact your local distributor to have the following preventive maintenance performed by a certified Engineer:
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
Have your distributor run a backlash program to check the backlash in X and Z axis and adjust if necessary
Have your distributor check the X and Z axis gibs and adjust if necessary

Your CNC machine is just like anything else – if you take care of it, it will take care of you.
