Hi there,
Does anybody have experience cutting carbon. I'm talking about solid carbon, not carbon fiber. There are many different grades but mostly the problems I'm having are with chipping and tool wear as it's very abrasive. Do you recommend slower speeds and higher feeds or faster speeds and slower feeds? Faster spindle seems to dull the tool quicker (rounds the edges) and slower spindle seems to chip the material. Using diamond roughers and diamond coated tools but price is sky high. Any suggestions??
