What tolerances can Insaco hold?
The nature of diamond grinding on ultra hard materials translates into tight tolerances being routinely achieved. The actual limits to the attained precision depend on variables like the machine tool used, the general shape and size of the part, and the sequence of operations needed to complete the task. Although our shop standard for machining is +/-0.004″, we generally halve this on the first pass of operations. Secondary operations can further narrow this to +/-0.0001″. Our flat lapping operations can best be recorded in millionths of an inch. We welcome discussions about desired tolerances and often provide constructive advice regarding practical limitations and cost considerations.
