I have a cnc x2 R8 spindle. What works best for facemilling taking light cuts? I was thinking about a 2" indexable endmill using 3 inserts. Any suggestions?
I run an X2 head. I use a 1.25" facemill with two carbide inserts.
I do have a belt drive and much stronger motor though. I get a real nice finish with it. It may have something to do with the rest of the mill being more accurate, bigger and stronger than a typical X2, but if you tram it nicely, you should get decent results.
I would not go any bigger than 1.5" though.
My X2 actually use a fly cutter pretty well in manual mode. It got a decent finish too.
CR, I've got the belt conversion. Just curious about a cutter.
Horse power (or lack thereof) is what can be interpreted , it's in the handbook. But it's basicaly trial and error unless you really do your calculations pecise.
This cheapo Face Mill from Wholesale Tool should do the job.
It has positive rake and a 15 degree lead angle so it won't need as much power.
A 45 degree lead would be better, you could take more aggressive cuts.
This should handle 2000 rpm and .025 DOC on the X2.
A good quality face mill, Kennametal, etc., one that's balanced, could go a lot higher in rpm, play it safe with the chinese stuff though.
