  • Grinding an inside taper – 5C Collet – Cuttermaster Air Spindle Tube on a 2021 Journeyman JXT

One of the more difficult things to do after making the Tube straight and round within .0002 is getting the 5C collet taper perfectly
in the center of the ground round after heat treating, hard chroming, and grinding. This is NOT an easy part, so Im making it easier.

So I whipped up this fixture (just waiting in the belt)   Now that we have a tool grinder with a tower, shank-mounted aluminum oxide wheel   Leaves a beautiful finish

Movies and Inspection results next
