Hello
The company that I'm working for is considering on a HMC purchase. Some of the minimum specs would be:
CAT 50 Spindle
6000 min RPM
500 to 630 MM pallets
TSC
We spotted a few Mori NH DCG machines. When comparing these machine to others (Mazak, Kitamura, Hyundai Kia ect.), we notice the Mori are some of the lighter machines (less than 30,000 pounds vs 40,000 plus). I'm a big believer in BIG Iron and I am concerned that the lighter Mori's might leave something left to desire when making aggressive cuts or tool life. A Sales person told us the Mori Seiki over came this by their "DCG" technology. Just wondering what the forum thinks. I do know Mori is a big name when it come to quality, but the light weight has me skeptical.
We plan on machining Alum. casting with long overhangs (5+ inches). the one part will require us to mill a profile 5.215 deep. with a .008" tapper. Currently we are using a custom 1.00" solid carbide EM to achieve this on a 50 tapper VMC (Haas VF-3). We would like to finish the full depth in one pass, radially, not so important. We would also like to keep some options open if we need to machine Steel Alloys in the feature, maybe even drilling large holes as well (1.250" plus). My company is not to interested in HSK's because we have other machines in the shop with CAT 50 would like to be able to share tool holders if needed. Not too concerned about '3d high speed machining'. Also be running low batch numbers so rapids/Tool change time not super important. Would like to keep the price less that $250,000 so we would have more money left over for tooling/pallets.
One last note, we would like to do "shop floor programing" if possible. Mostly will be doing 3+2 machining, drilling holes and simple contours. Is the MAPPS software any good? Or are we better off using CAM or g-codes? Currently, 75% of our programing on our HAAS/Fanuc VMC machines are done on our shop floor.
Thanks for your input.
