Re: Swapping from permanent magnet motor to servo question
My lathe is a Hercus Compulathe. It's small. The chuck is 4" (100mm). Current spindle motor is 500 watts. Material I want to drill is 0-1 and A-2 tool steel. I would like to use the C axis to engrave a part number with one live tool, and drill a center hole. Maximum drill will be .129" dia...

Re: Swapping from permanent magnet motor to servo question
Lol ok that's a lot bigger and more expensive than I was hoping for.
I guess maybe I should abandon that idea. New question is how big of a servo do I need if I just want to replace the motor and use it as a spindle motor only.

Re: Swapping from permanent magnet motor to servo question
Unfortunately it will be worse than 1:1 when in high speed range.

Swapping from permanent magnet motor to servo question
The recent discussion about the C axis lathe got me thinking it might be interesting to try on my lathe. I currently have a 180VDC 500 Watt permanent magnet (3/4 horsepower) motor powering my spindle. My question is how to choose a replacement spindle motor. I think it's likely that I can't just swa...

Re: C-Axis for lathe (construction in progress)
Very nice. I was wondering if it was possible to do engraving in a lathe. Now I know it can be done.

Re: Novakon M200 w/steppers
Do you have mechanical or proximity sensors for your limit switches?

Re: Lathe-ATC 4bit-grey-code_1-output not working, can someone help me?
If I type M6 T3 in my MDI line nothing happens. For me to change a tool the format to make the turret move is T303 then I press cycle start to execute the tool change.

What exactly are you typing to activate a tool change in the MDI line?

Re: New Rebuild on Sherline Chucker Lathe & New build on 5400 mill
I think the increment on mine is .0005". A complete rotation of the needle is .030". I looked them up, probably worth having one at at some point. thanks for the input on these I did not know they existed. They have many uses but in my case are most often used to align the fixed vise jaw ...
