[QUOTE="CoolHandLuke, post: 292274, member: 4850"] I understand your reasons Lindsay, but i'm only going to say i really am disappointed in the people here who accept faulty work coming from their machines, accepting it as Normal, and suggesting this is what happens for everyone. this is by far NOT the case for anyone who operates their milling or printing with Quality assurance and standard Quality Control checks in-and-out of the machines. yes, I understand in this instance its not your bridge, not your mill, that does not mean these checks and balances don't apply. clearly whoever made this bridge for you needs their process examined. the best way to mill a bridge is *right the first time* not "anything will do, even if i have to grind it" you should not be accepting product from a machine that does not produce what you asked it to produce. Measure your product qualitatively and modify the milling parameters to suit. the only part of this process that should be unacceptable is thinking that the machine and the CAM doesn't need modification straight out of the box. the people that do this need to have their products thoroughly examined. all that being said, the ceramists i used to work with used to swear only by irrigated handpieces for grinding zirconia. as for the tools they used i can't say because i don't really know.
