How to assemble your grease gun

Gear Rack Greasing

Gear rack on the table axis and gantry axis can be greased with either a dry teflon lube (every 3 months) or a multi-purpose lithium grease (every 6 months). If your machine is operated in a dusty environment, it is recommended to use dry teflon lube.

Ballscrew & Linear Rail Greasing

We recommend greasing the ballscrew axis and linear bearing blocks on your machine every 3 months. The videos below provide instructions for this procedure. Choose the appropriate video, based on the purchase date of your machine.

Component Replacement

There are only a few mechanical parts that should ever need to be replaced on your PRO CNC machine. It can be helpful to have these on hand to avoid machine downtime in the event of a machine crash or other issue.

It is recommended to replace the Rack and Pinion Drive Spindles every 6 months (based on an average of 20hr/week of machine use).

Spare parts bundles are available for both NEMA 23 and NEMA 34 systems.
