Thanks for all the input. That project is on hold for now. Ornerynorsk-thanks for the speed tip, It does work at faster speeds. Also, I tried a 3/32 4 flute end mill and it seemed to walk around so stopped. Could that be the wrong application of the cutter and or material? And what about...
The cutter(s) are both HSS and Carbide, 200 rpm was suggested by the tool maker. The bolt is an of the shelf grade 3, I don't know the alloy. It works, but too many things don't feel right on this one.
Make sure they take there breaks, and maybe then some. I'd also suggest they get up and move around in between breaks. production might go down, but Workers Comp premiums might be cut down.
I don't have the parts in front of me... so this is an estimate, I the the bolt is 1/4-20 x 4". The cutter is custom cut, about 1/4" dia. Some history...before me about 60 were cut and 5 cutters broke, the shank is ground down to 1/8 or smaller. Which makes it very delicate. It's not my choice...
I'm using a 3/32 round cutter for two woodruff key slots on a 4" bolt. I'm having a hard time repeating from part to part. Not exactly sure how to center the cutter. Any ideas/ help on setting this up?
I was also wondering if an endmill would be a better way to go.
Thanks in advance!
Sorry...
