Spindle lock for PM25 CNC milling machine (improved)

Kent VanderVelden

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.

Milling Machine to CNC Conversion – Precision Mathews Part 2

Today we’re converting a manual milling machine to CNC. We install high quality ballscrews, ballnuts, and angular contact bearings on first the Z axis and then the Y and X axis. We also install stepper motors. This video features tips and techniques that I have developed over the past 10 conversions or so. You’ll even see hardware from the first CNC conversion I ever did that was made on a manual milling machine. I learn something new every time. Please share your own CNC conversion tips and experience in the comments below.

This conversion utilizes the Centroid Acorn control board. Let me know if you would like to see video content on my specific setup:
