At my old place of work, they did a lot of diamond turning, however, the carbide they were machining was 20-25% cobalt. The carbide we use here is 10% cobalt, so a lot harder and more brittle. Im putting the question out there that is it possible to diamond turn such a hard material? And if so, any advice on tooling, speeds and feeds etc will be very helpful. We have multiple CNC lathes, so we are equipped in that department. Our general sizes are between 3mm to 25mm, with our longest rod at 330mm.
Any help on this matter will be extremely helpful, thank you, Gareth.
