[QUOTE="J E Custom, post: 1471824, member: 2736"] Thanks GordO. That is some more good information, and I like the looks of that Insert. I use mostly Sandivk carbide tools, but I will have try Some of those. Spindle RPM is the real Problem with shop lathes when using a carbide insert. Mine only goes to 1800 and anything past 5 or 600 rpm scares the crap out of me, plus I don,t have a good oil flush system because of the requirements to cover up the machine. So I do things at a slower pace to save my tooling. When chambering, I use anywhere from 45 RPM to 175 RPM depending on what the reamer likes. (Most do their best at 45 to 70 RPM and don,t require any polishing) With the different steels used in barrels everything has to be adjusted for best results depending on the barrel material. most stainless barrels are ether 416 R or 17-4 PH and they have different requirements. CNC machining is an entirely different process and what works best for it doesn't for the shop lathe most of the times. All the tips posted so far are appreciated and I will try to use them if possible. Again , thanks to everyone for their post. J E CUSTOM [/QUOTE]
