Ballscrew machining details

[HiltonSteve]

Just came across this and thought it may be of use to people looking at machining their own ballscrews, it shows the 'standard' threads and bearing dia's. -

anyone have something similar for 12mm ballscrews?

[HiltonSteve]

No but I do have some 12mm ballsrews that I could measure for you...

Not tonight though as after too many pints the tolerances get wider...

Hi
Marchant dice have some dimensions at http://www.worldofcnc.com/images/Machining.pdf
although it appears that things have moved on the thread front in that the one I got from them had an m8 x 0.75 thread.
A finer than the m8x1.0 on the list which meant more expense buying a tap and die which I had to buy as the other ball screws did not have the ends machined.
