Hey all. I'm having some issues with spindle runout on my PM940V.
The primary bearings are 7207AC (35mm X 72mm X 17mm angular contact).
Stupidly, admittedly, I did not note how the bearings are...

Do ya know if their collets are close enough to be able to use more than one, and still use the same tool offset?

Anyway, the referenced book sounds interesting. I may try to budget it in.
In the mean time, I am not into becoming a...

Thanks for the interest. The question is a serious one. I, like many others, would like to build a benchtop mill. The design portion is fairly straight forward. The controls are also fairly easy,...

A very basic question for the machine builder. How square does a machine structure need to be? And how does one build it square?
A standard 3 axes machine (cnc or manual) needs 3 orthogonal...

Hepco is distributed by Bishop-Wisecarver in the US. you get a double markup, especially with the dollar upside down to the pound and the euro.
