High Speed Steel M-17 grinding
(OP)
I need to get some parts ground 0.350" long down to 0.009" dia. at the very tip. CNC type profile and Rc=60-62. Starts with a die pin at diameter and the o.d. profile is on the last 0.150" of length. Do I cut then harden? Getting no takers.





RE: High Speed Steel M-17 grinding
It is much easier to start with a pointed pin than grind to a point. This because the machines that make points can make various points with no problems at a very low costs.
It would appear that the overall length might be the hang up in getting quotes though someone like National Jet may be able to help you within certain limitations. You might have to go longer and part to desired length.

Another possibility is contact someone like Bagshaw. They made a lot points for us.
