so it is titanium. well uncoated inserts are the choice then. ridding yourself of this pesky sandlike substance really boils down to more coolant volume/better filtration.
since chips not staying at part, carbide will last longer.
now jes fer giggles.........try bumping up/down yer speeds and feeds and see if you actually can create a curling chip. start low and then go up.
remember.........someone else has machined this material before. is titanium domestic or off shore? find out from your supplier who else he sells the exact same rockwell titanium and then call them and see what the hell there procedure is for moving chips.
your distributor salesman gets about 1 days worth of carbide/coolant schooling out of a year.
for carbide and coolant call territory salesman and say its a "code red"!
if neither one of them satisfy your problem then call regional manager.
regional mgr. can contact factory and do exact mock up of your operation under ideal conditions and then give you exact MOT and mfg. of coolant and method of expelling chips. and how often you have to change coolant.
but..........ask yourself this. how many of these parts and how long do you plan on having job. if its a short run prototype..........bite the bullet, suck up, burn up carbide and coolant, quote the damn part high so you make some money and then move on.
