    1200rpm (630SFM) was waaaay too fast. Spark show. Running 570-600rpm and 0.004ipt is working well at about 0.05" DOC, but I'm getting a ca. 0.001" step without taking a finish cut. I'll try...

    I often have to cut with coolant since I don't have air blast but for face milling I will be fine and can likely kick the RPM up. So I tend to keep the SFM low to keep the heat down. That said, I...

    I'd ramp down with a 0.125" high feed (or corner radius) end mill and then finish with a ball mill if needed (also with a shallow ramp).

    Well the machine has a maximum of 36 ft.-lbs. at 1500rpm... should I start at maximum torque and just see what happens? I usually like to run the 2" face mill at about 800-900rpm in alloy steels. ...

    Thanks for the replies!

    There are some crazy tight calls on these parts, so roughing, then heat treating, then finishing would have been a PITA. After talking to folks around here and at the heat...

    I bought the Yukiwa for the old day job on a 700 and it was really nice. We built a 4140 riser for it to get larger square parts to be able to rotate. The R650 got a Nikken but I didn't spec that -...
