This is the type of lubricant you want to use if you have a CNC. I have serviced a few machines that people had been using wet type lubricants and among them WD40 and the wet lube attracted dust, built up and packed into the bearing pockets and bearings and caused them to grab and make high pitched squeaks with every move. They just added more lubricant to remedy the problem but it just made things worse.

After cleaning up everything, and that was not fun and took forever, the machines were re-lubed with dry Teflon lube and they were surprised how much difference it made. I haven't been back for service on any of those CNC's for that problem.

Bottom line wet lubricants and saw dust don't go together!

Mike,

Can you use that on the tubes and lead screws instead of oil?
Stick beat me to it. WD 40, 3in1 oil, motor oil and other lubrcants that stay wet are not good to use because of the sawdust build up. Dry lubes are the best.
