Definitely not to use PCD for finishing oilite. The top rake is normally negative, the the tip generates heat to move the material. If you use a carbide tip, get one specifically for aluminium, sharp and polished.I figured I’d ask Oilite and they just received an email back....referring me to the link about machining practices. It appears they have updated “carbide inserts to PDC.
Kyocera's diamond material is a synthetic material sintered under high temperature and high pressure. PCD(polycrystalline diamond) is ideal for non-ferrous metals, non-metal turning, milling and other types of cutting.
I’m assuming that skimming .0005” or whatever off the bushing doesn’t qualify as major machining, so no re-impregnating would be required.
Anyone here versed on broaching, burnishing, or ball sizing? Seem to me I read something somewhere written by (I think) John Healey about connecting rod small ends being done that way. I think the term broaching was used, but wouldn’t bet my life on it.
Why would one be so focused on oilite bushes in the camshafts when you have continuous lubrication into them ? I´d take tin bronce (phosphor bronce?) any time instead. For sizing oilite bushes a simple HSS tool should be allright - as long as it is not blunt. And speed is only secondary to sharp cutting tools. Vic
