Never never ever would I do this to my Bridgeport. Use a 9" Wildcat grinder would do this job quick. Your shop, your rules, but using the Bridgeport is just abusive to the mill and that carbide cutter is not cheap. Not trying to be negative, just stating my thoughts. ---Doozer
No, not negative! I cut far worse things in that Bridgeport, but I mostly use it for squaring up stock or punching holes in mostly square blocks. It's accurate way out in the travels and has a super nice new DRO. It's my workhorse. Now, I would probably never cut these in my CNC. It's just more valuable to me and the parts I produce.
Take your intro from 1 min to 15 sec. While this technique might be good for precision parts, for a blade that will be going through dirt and other stuff in no time, this is overkill and a waste of both your time and the milling maching. Get an angle grinder and use a jig. It'll not only be faster, but cheaper in the long run and easier.
Point taken on the intro. I'm a machinist who makes aerospace components and telescope parts. I just don't have a big grinder. I've got a Milwaukee 4.5 18v angle grinder, and removing this amount of material would take an hour per blade. I've got a Brideport and nearly an endless supply of end mills sooo....
They actually make a blade sharpener for lawnmower blades I used to have one and I sharpened many blades off of a bush hog very similar to those !!
