Micromachining

So what’s micromachining? Everyone has a different definition, but a common view is machining with tools smaller than 0.015 inch in diameter and tolerances of just a few tenths. It takes significant spindle speed to effectively use such small-diameter tools, and the machines have to be very accurate. One of the biggest challenges of micromachining is finding cutting tools that offer the long life and repeatability that enables a machine tool to run at high rpms.
