So im pretty ticked off. So far Ive spent a very long time researching learning and modeling up my first project. I goto cut it today and already destroyed my project. ar15 lower from a 6x9 hunk.
Im using pcnc1100 with an power draw bar and TTS. Im using brand new 1/2" 2 flute ticn coated end mills(niagra, cleveland etc). Im doing some slotting cuts at 0.1 depth, 2764 rpms, and about 13 ipm...
Lots of chatter and tool pull out. Ive cleaned the collets with alchohol tripple checked my draw bar tightness to the point where it wont even pull out without almost full psi. (just for testing)
EVERY slot chatters and tool pulls out. Ive tried it at much slower ipm still issues. Ive tried it with different holder and other 1/2" cutters still same thing. Not sure what to do. I cant even use my mill.
How deep / fast are you guys cutting with 1/2hss slotwise..
Also now when i release the tool with the pdb i get the hiss.... then a pop at release. Asuming its just sticking and poping out but not sure what that is normal.
heres a pic
Tool pull out not a ramp
Thanks for any help!
