Boxford TCL125 CNC Lathe, 3rd AXIS.
by John
Below is a video which was recorded by my machining mentor friend, Stuart Tankard. Stuart made a milling attachment for his Boxford CNC lathe, and he demonstrates it in the following video by making some lovely small valve control handles.
I followed in Stuart’s footsteps by making a similar attachment for my identical Boxford 125 CNC lathe, but I have not yet video’d it in action. Not much point when Stuart’s video is so good. I really like the absence of irrelevant, irritating music. Just machining sounds. Enjoy. (if you want to see it full screen, copy the YouTube address from the settings icon).

This is s such a great Mod John, but how the hell do you get the Servo spindle motor to switch from speed to position?! I thought about putting in a physical switch to the servo drive , but how have you done it?

Hi osrixmods, the spindle motor is an AC Servo which I purchased from Fastobuy2017 on ebay. The motor manual lists how to switch from speed to position, but from memory one of the inputs is open for speed and closed for position, or vice versa. Mach3 codes M111 and M112 then select speed or position. There is a 12v, 2 contact relay to install. If you need more information than this I can put you into contact with Stuart Tankard, who developed the mod. John

Hi, very nice parts. I have just bought a Boxford 250PC. I was interested to see your chuck and would like to copy. Can you tell me what threads the spindle is and if they are left or right handed. Many thanks Stewart

Hi Stewart,
It is a standard ER32 collet chuck and the threads are M40x1.5 right handed. The tricky bit is that a backing plate mounting the ER32 to the Boxford 125TCL needed to be custom made, which Stuart did and I copied, using his plans. I expect that the plans would need to be modified to fit your 250PC. John
