dskinsler83 Posted May 11, 2014 Share Posted May 11, 2014 going to fast huh? Yes and to deep ea pass and using the wrong mills I learned I need to use 4flute square end to do the majority and then at the last couple shallow passes us the ball end Link to comment Share on other sites More sharing options...
StraightUp_OG Posted May 11, 2014 Author Share Posted May 11, 2014 (edited) Yeah it is. First rule of thumb slower is always better. Also listen to the mill. If you are getting chatter or squealing something is too fast. Smaller cutters need a faster RPM. The bigger diameter the slower the RPM.

dskinsler83 Posted May 11, 2014 Share Posted May 11, 2014 Well I'm being told due to the hardness of the striker I have to use a speed of around 450-500 rpm Link to comment Share on other sites More sharing options...
StraightUp_OG Posted May 11, 2014 Author Share Posted May 11, 2014 That may be the case. Link to comment Share on other sites More sharing options...
StraightUp_OG Posted May 11, 2014 Author Share Posted May 11, 2014 (edited) For example I used a 3/8" 4 flute square end mill to cut the flat on the G19 slide for the RMR. My RPM was about 400-500 but I was only taking .005" per pass with a slow feed as well. This is because that slide is diamond hard. I really just listen to the mill and watch the chip load. It will get easier and once you hit the right formula write it down, rinse and repeat. Edited May 11, 2014 by StraightUp_OG Link to comment Share on other sites More sharing options...
dskinsler83 Posted May 11, 2014 Share Posted May 11, 2014 The pic I put up is not final product just playing. But that is what the general use will be for for now. My other pics are too big. Link to comment Share on other sites More sharing options...

dskinsler83 Posted May 11, 2014 Share Posted May 11, 2014 I ended up chipping another end mill and heard it happen and then I dulled one by using the length to cut the end cut in the end pm me your personal email OG and I'll send you a pic of what I mean Link to comment Share on other sites More sharing options...

StraightUp_OG Posted May 12, 2014 Author Share Posted May 12, 2014 I see what you mean and yeah the new way you are doing it is correct. The cutter will last MUCH longer now. Link to comment Share on other sites More sharing options...

StraightUp_OG Posted May 12, 2014 Author Share Posted May 12, 2014 I will mimic the set up in my mill and post them. Stand by to stand by... Link to comment Share on other sites More sharing options...
dskinsler83 Posted May 12, 2014 Share Posted May 12, 2014 I wonder what speeds one will run this and if these measurements will transfer to GLOCK slides for the BoMar info? Link to comment Share on other sites More sharing options...
kevinj308 Posted May 12, 2014 Share Posted May 12, 2014 (edited) @dskinsler http://www.cnccookbook.com/CCGWizard.html I bought a 1hp version of this for speeds and feeds. I'm pretty confident it's paid for itself already in end mills. There's a free trial period, check it out.

StraightUp_OG Posted May 12, 2014 Author Share Posted May 12, 2014 You want the work piece horizontal to the cutter. Link to comment Share on other sites More sharing options...
kevinj308 Posted May 12, 2014 Share Posted May 12, 2014 For me it gives a good rpm to use and the feed I still do by feel. If I know I'm at the right rpm then the only variable is how hard I feed it. That goes for end mills, drill bits, boring bar, everything. The cutters start to add up after you smoke a few, I learned. It's free to try. I liked it and bought the cheapest version. Been pretty happy with it. Link to comment Share on other sites More sharing options...
dskinsler83 Posted May 12, 2014 Share Posted May 12, 2014 You want the work piece horizontal to the cutter. I do the side the way you have it in there. I will try the end cut like you have it in there. Link to comment Share on other sites More sharing options...
StraightUp_OG Posted May 12, 2014 Author Share Posted May 12, 2014 (edited) Cool I just used a single parallel bar to support it from the bottom while getting a good bite on the striker with the vise. Edited May 12, 2014 by StraightUp_OG Link to comment Share on other sites More sharing options...
