I occasionally work on projects for food grade facilities and the material of choice is stainless steel - mainly 304. I usually send out parts to be laser cut and I have used a manually-operated mill on occasion. After seeing the precision parts made out of aluminum, I began to wonder about making that OX or ROUTY type CNC that would work for stainless parts. I know that serious milling done on stainless requires a very rigid frame and usually has a stationary spindle with moving table, like this: But I also see some stainless cut on a gantry type CNC using slow speeds and multiple shallow cuts, like this: I'm curious if anyone has tried using an OX or something similar on stainless? What were the results? Here are some things that I think will be key to success: - slow speed: 10 - 20 ipm - shallow cuts: ~.02" - temperature control: continuous cutting fluid spray / air stream http://www.ebay.com/itm/mist-coolan...052?pt=LH_DefaultDomain_0&hash=item19efd77844 - solid spindle with a solid mount: http://www.ebay.com/itm/CNC-2-2KW-S...497?pt=LH_DefaultDomain_0&hash=item3a93347021 - a bit designed for use with stainless: http://www.ebay.com/itm/ONSRUD-83-3...401?pt=LH_DefaultDomain_0&hash=item33906c9991 Any thoughts on this? I like the OX style, but will be able to get precise results? Will there be too much vibration? Will the added strain of cutting stainless versus wood or aluminum result in stretched belts and more back lash?
