Have been trying to use a diamond-wheeled cutoff saw with electronically variable spindlespeed and feed to cut through a block of titanium diboride.
My problems are heat development and walking of the saw.
Altough there`s a nice stream of coolant available on the cut and the walking bit is solved by slowing the feed...things are still heating up too much.
Causing the sawblade(0.4 mm thick) to get caught in the material.
I suspect that by slowing down the feed there`s more rubbing than cutting going on....so do I go looking for a coarser grit on the blade to minimise the rubbing action and thus heat-development ?
Or do is just need less spindlespeed ?
