Removing Cutting Debris from the X and Z Axis

After thoroughly cleaning the exterior of the machine with various brushes and the vacuum, begin to clean the interior.

Pull back the covers on the X and Z axis and remove cutting debris that has built up during the day with a brush. Then use the vacuum to thoroughly clean. It may help to remove the covers via the philips head screws at the ends to better access the internals.

Removing Cutting Debris from the Y Axis

If you have not done so already, move the table to the rear until just before the rear screws become hidden. Make sure the machine is turned off before moving forward.

To access the Y axis, first remove the screws that are holding the cover in place. Remove the cover by lifting the front part slightly and pulling it back towards you. Once you have removed the cover you can use the brush and vacuum to remove cutting debris. Reverse the steps to reassemble.

Greasing the Ball Screws

As a general guide, it is recommended to lubricate the ball screws for each axis every 1000 hours of use or at the end of the semester. Access each axis’ ball screw in the same manner that you would clean them if you were performing daily maintenance. Always use No. 2 lithium grease and never use any grease containing silicon.
