I have been hesistant about using a parting tool, but on this last project I picked up a 1/8 in wide Cobalt parting tool....on aluminum no problems even though the tool was set a bit above center....then tried the same on 12L14 and some chatter...probably from the rubbing...lowered the tool to just below center....and it cuts well most of my cuts have been around .003 to .004....since I'm using a QCTP, the parting tool is held as some angle...I'll check that angle....it appears to be 30 degrees or less. |
