My Pm932m-pdf Journey.

It's 6 inserts. I bought some inserts for steel too but I haven't used them yet.

I picked up some 1" X 3" drops of aluminum bar from work today to make some vice soft jaws out of. I want to try to make a video of the process. I need to do a little research first though.

.055 depth of cut, full width, full speed on the spindle, full speed on the auto feed. No problem at all.

At a .260 depth of cut I had to slow it down to #3 of the auto feed. Man, was it throwing some big chips at that point!

Nice!

My 2.5" should be showing up tomorrow. I have some 7075 T6 drops that I need to square up and get rid of the corner/edge dings. It looks like you cut dry? I will try dry and with the FogBuster to see what results I get.

If you did that with a 3" I should be fine with my 2.5" at 2k spindle rpm. Not sure I want to try 3k...

Dry, yes. I have a Noga mini cool system but I haven't set it up yet. I need to make a tank and hook it up to the compressor.

Nice finish, I am in the same boat as Bill, 2.5" cutter with 5 Octangular inserts. One head for aluminum, another set up for steel. Can get 2 insert sets out of a box of inserts, I think Shar's has a new cutter head that the inserts can be flipped for more cutting edges. I run my 2.5" at around 2200-2400RPM at 10-15 IPM with 0.050 - 0.100" cut for fast removal in aluminum, and finish cut of under 0.010". When possible I prefer to spin faster and take more passes at higher feeds, not CNC level, but I can run up to 40 IPM on the X-axis. Just not comfortable with deeper cuts when facing material with my mill set-up. Also have the Noga mini cool system that I have modified, but haven't run the compressor lines and the tank system. I do fine with aluminum with a little local coolant application, but really could use the Noga/air when slotting.
