Hi,

I hv got a drawing from my customer for machining of stainless steel stud D-3" x L-117.46" with a run out of 0.02".

It also has 5 grooves to machined on its surface and a hexagonal hole (stamping) at one of its end for 0.48".

Can anybody assist me on what process with machine details to be followed for this ?

You might purchase shafting PBC Linear - Your Source for Innovative Linear & Rotary Motion Bearings, Systems, Technologies, and Solutions. (http://www.pacific-bearing.com/templates/Round_Shaft_Technology_Template.aspx?id=8942)

And then do the holes and grooves by EDM.

The problem with shafting is that it's hardened.

Maybe you can convince someone to sell it before it's hardened.
