Spindle lock for PM25 CNC milling machine (improved)

March 30, 2023

An improved spindle lock is added to the Precision Matthews PM25MV milling machine to safely and quickly change the tool. The improvements include a switch to tell LinuxCNC when the spindle is locked, preventing attempts at motion while locked, and a change that hastens operation. The spindle lock is installed inside of the head to avoid changing the belt drive or the belt guard. Faster tools changes greatly improves the productivity of the CNC conversion. Spindle lock concept may work on similar mills, e.g., Grizzly G0704 and Titan TM25.

Precision Matthews PM-940M CNC Milling Machine un-crating

Propslayer Fabrications

February 27, 2023

My Pm940m-CNC Finally came in and I though I would do an un-crating video with some talk about about the mill.

You do have to email and ask for the PM-940M CNC version as all they list on their website is the non cnc version. They sell both a VFD and a Non-VFD version.

I got the non VFD version and it was $7,347.00 with freight shipping. I went with the non VFD version as I eventually plan to run this machine on LinuxCNC and didn’t want to have to spend more to get a compatible VFD if the one that would of come with the mill didn’t work.
