She was only at 60% spindle load with lots of RPM and feed left in her
Hitachi Seiki VS40 high grade (30hp die and mold spindle) with a Widia 2" jobbieIs that the Mits?
Just 6061 2" x 6" x 19.5" bars.What material?
I used to work with a machinist that programed and ran the CNC mills.Just 6061 2" x 6" x 19.5" bars.
That was 520 ipm. I ran it up to just shy of 800 ipm with override, but it cuts a little undersize so I'd have to run G8P1 to put it back on path. I'm gonna check the the specs on the cutter and see if I can jump the helix stepdown from 0.060" to 0.090. If I can do that and stay at 520 ipm that will put me right around 100 cubes per min.
Only have 15 parts to make so I'm more just having fun playing around since I don't run aluminum that often.
Hey roughing is where there is lots of money to be made.I used to work with a machinist that programed and ran the CNC mills.
He loved pushing machines, ran over 100% all the time.
One day I designed a large bending die, that was milled out of a solid chunk
of 9" thick MS, 18" x 32" section was carved out....he about blew a load in his pants when I proposed that method, over the old way of a weldment, with less machining. IIRC about 75% was removed as chips.
He did very good on the job, and we saved money.....However when he retired, the next one was back to normal welding.
and when I left, they don't really doo much anymore, and certainly NO regards to saving money.
I definitely enjoy roughing and trying out new things. That video was 520 ipm (actual feed). IIRC I got up to around 800 ipm but it was cutting undersized at 800 cause I didn't have G8 tuned for moving that fast.I like doing that kind of stuff. I made a lot of flywheels around 1.5" thick 1045 that got 3.5" lightening holes through them. I did the holes on my old 1982 Mori MV-45 with a 5/8" endmill spiral full depth and spiral out. 6M Fanuc maxes out at 141 IPM, but that looks pretty fast in a pocket that size.
