Does anyone have any experience with boring silicone grommets in a lathe?
I think I have the workholding down, but the problem is the tool. I used a 3/8 2 flute endmill oriented like a boring bar to get a high shear angle, but it made a nasty finish and just kind of pushed the material out of the way.
I don't know the exact type of silicone it is, but one was brown and one was yellow. The yellow one was quite a bit firmer.
It is 1.025 OD x .5 Id x .78 long and I need to bore it to .55 dia.
Any help is greatly appreciated.
