Machine tool cutter grinding in my garage machine shop. This video shows basic set up for grinding the helical flutes on an endmill in the standard work head using a finger rest. I also touch on grinding primary and secondary relief angles using the flat and hollow grinds, and indicator drop method for non-tilt head machines.
This video is another showing how I apply the cutter grinder for my needs and the ability to further take control of the cutting edges and angles for special applications.
The cutter I have in the head I ground with the tooth pointing upward, that is more risky and cant be done with some cutters. It is best to start off with the sharp edge pointing down.
