Re: Correct lubrication for milling tufnol
- Hi Barry
I tried it dry but it seems to produce a 'fluffy' surface. I also posted this on the 7x12 lathe group. Someone there suggested water which does give a better surface finish.
I have since tried thick cutting oil and wd40 as well. Water seems best, but wd40 is close. Cutting speed from the internet is 600fpm. With a 12mm endmill flat out I get just over 200fpm. Higher speed seems to help a little.
