Re: [CAD_CAM_EDM_DRO] To Convert or not to convert- That is the question!

Very interesting!

But now I have more questions than I did before!!
Do you still use the existing leadscrews on a typical CNC retrofit? and if
not, what do you replace them with?
Also, the table on my Clausing mill is only about 6 inches wide and 18
inches long. would it be a good candidate for a CNC retrofit?
