Very interesting and informative. I appreciate how you describe what you are doing, why, and how, rather than just doing it. I am learning! Lovin your T&C videos.. Your videographer is doing a great job! Close ups when needed.
I purchased an Astra Elite AR5-E a few years ago and have watched a lot of videos and gotten pretty proficient on it. However i never knew how to do center grinding endmills, i certainly do now. Thank you. Would love a video on dovetail cutters. Not many videos on that and thee are quite a few angles to consider. Thank you again, subscribed.
found this very informative,,, so much more to it than meets the eye. i have recently got air spindle ,,, end mill etc. sharpening set up. oh by the way, did i mention i don't have a bloody clue how to use it?? hoping to learn from people like you cheers from australia! ( subscribed!)👍👍
Imagine if you could generate the helix for any cutter without having to use the finger rest to guide the cutter.......I'm working on a design that I thought up some years ago.
You're right that it causes a bigger burr I do it this way because the cutting force of the wheel forces the tooth face down onto the pointer. By rotating the wheel the other way the cutting force would be trying to lift the tooth face off of the pointer which would result in the wheel digging deeper into the side of the end mill, which would result in more cutting force and could lead to a crash where the cutting force is so great that you lose control. This would destroy the end mill and possibly cause the grinding wheel to come loose and go scooting off across the shop. I find that dealing with the bigger burr is the lesser of two evils.
I don't use air any more because when I did it would always get "sticky" usually in the middle of a cut. I've always got the best results by keeping it nice and oily. And thanks for watching
One of the most informative video on end mill sharpening I think I’ve ever seen, thank you so much.
Thank you for the kind words

Thank you
I just realized that I have a dull dovetail cutter. Thanks for the great idea. I'll put it on the list

Very nice work sir.
Many thanks
awsome content
Thanks!
Cool! 👍👍👍
Thank you! Cheers!
if you tap a grinding wheel lightly with something it should ring. if not its cracked.
Great video, a piece of copper will debar
Thanks 👍

Hello, just wondering why you have it so the direction of the wheel direction will raise a burr of the cutting edge ?
You're right that it causes a bigger burr
I do it this way because the cutting force of the wheel forces the tooth face down onto the pointer. By rotating the wheel the other way the cutting force would be trying to lift the tooth face off of the pointer which would result in the wheel digging deeper into the side of the end mill, which would result in more cutting force and could lead to a crash where the cutting force is so great that you lose control. This would destroy the end mill and possibly cause the grinding wheel to come loose and go scooting off across the shop. I find that dealing with the bigger burr is the lesser of two evils.
What is the reason for not using air in the air bearing?
I don't use air any more because when I did it would always get "sticky" usually in the middle of a cut. I've always got the best results by keeping it nice and oily. And thanks for watching
mill sure are expensive, but it sure looks lie a lot of work to refurbish them
It isn't so bad if you do a bunch a a time
I feel so poor and primitive doing this by hand with a die grinder. :/
