2012年11月5日 · The Darex and Cuttermaster are 2 of the smaller benchtop machines that can still be very expensive even used, and are almost solely limited to end mill sharpening only.

2014年4月14日 · I'm thinking this process is often done with a thin cutoff disk since it doesn't appear nearly as finished as the relief behind the cutting edge. Here's a picture of a 4-flute mill for reference. The gash I'm referring to is just to the right of the arrow labeled "end teeth". Any suggestions as to what tool to use would be appreciated.

2019年2月14日 · I had a bunch of end mills that needed sharpening. I did a search on the internet and found a few companies that sharpened end mills. I contacted the different companies and eventually decided to give Gruschow Grinding a try. I sent some end mills to Brian at Gruschow Grinding to be sharpened. The end mills came back very sharp.

2016年7月4日 · Sharpening the ends of end mills is very easy. It is ground like a drill is..... A primary angle usually about 7 degrees..... A secondary angle for clearance.
