Combining the robotic arms with a reliable CNC grinder is our formular to control tight tolerance in a mass production environment. Each collet is inspected 3 times at 0, 120, and 240 degree at 4 times diameter to guarantee the 5 micron (0.000197") runout tolerance. This inspection process is also repeated 3 times with fully disassemble collet from the collet nut and the tool holder to guarantee consistent runout tolerance.
