Maintenance
9.1.1 Rust Prevention
Exposed iron and steel surfaces will rust if proper care is not taken to protect them. The following
recommendaons will slow or reduce the onset of surface rust.
• If possible, install the PCNC mill in a temperature- and humidity-controlled environment.
• Always use a ood coolant recommended for machining; never use water or a coolant that
does not contain rust inhibitors. When using a water-based coolant, always mix the coolant
concentrate to the diluon rao recommended by the coolant manufacturer.
• If the mill is not used for more than 72 hours, apply a light mist of water repellent oil such as
WD-40 to the exposed bare metal surfaces.
• Trapped areas are suscepble to rust. Apply way oil or machine oil directly to the table surface
under the trapped area when you mount a vise or xture on the mill.
NOTE: Light surface rust on the table can be removed with a machinist’s stone.
9.1.2 Way Covers
Way covers serve an important funcon – they keep chips and abrasive debris from damaging the
slideways. Clean and inspect the way covers per maintenance schedule.
9.1.3 Flood Coolant System
Regular maintenance of the ood coolant system will prolong the service life of the coolant pump.
• Collect tramp oil with an absorbent pillow or a mechanical oil skimmer. Replace pillows as
needed.

• Coolant can scum if allowed to sit for a prolonged period. Replace coolant as needed.
• Check the impeller for obstrucons.
• Clean coolant reservoir regularly.
NOTE: Check with local authories on proper handling and disposal of new and used coolant.
