1. Daily

• Clean all debris off machine (blow off with pressurized air after every part)
• Inspect toolholders for cleanliness **
• Inspect internal taper of spindle motor**

2. Weekly

• Check pneumatic oil level in regulator*
• Empty water in regulator
• Inspect blower pre-filter and main filter, clean as required
• Grease all leadscrews and runnerblocks***

3. Monthly

• Upload all machine data via RS232 or ethernet (machine parameters and program files)
• Copy machine data onto floppy disk and store in a safe location
• Inspect all pneumatic connections, listen for leaks and inspect enclosures for excess oil*
• Inspect all electrical enclosures for cleanliness (power to machine should be off)
• Inspect all belt and pulley assemblies for tightness and belt integrity
• Clean and grease fourth and fifth axis gear assemblies***

4. Semiannually

• Deep clean all lead screw and ball nut assemblies by flushing ball nuts with WD40
• Clean dry assemblies, then perform error calibration on all axes
• Inspect all wiring connections in machine enclosures

*Machines require 10-weight pneumatic oil for lubrication of cylinders, pneumatic drills, and mechanical moving components within Colombo type spindle motors.
Machines with HSD motors should not have oil in their regulators. Pneumatic oil may be applied directly to cylinder shafts for these machines.
** Tool holders and spindle shafts may be cleaned using rust inhibitor solvents.
***Recommended grease: Lithium based multi purpose grease.
All safety procedures of individual companies should be followed.
Only steps which require machine operation should be performed with power on.
When using pressurized air to clean electronic components, ensure there is no moisture present.
