Not a whole bunch of machinist discussions on here. Probably better to post in the metal/fabrication section.

Looks more like a toy to me compared to the one's I've installed on mills.

This one comes with a ball screw to replace the old Acme screw to make it far more accurate.
Can move up to 100" a min.

I've got a lot of experience in heavy machine shops and I'm not so sure that ball screws are a good replacement for the old Acme screws accept in applications that require extreme accuracy. There are many old machines running that were built during WWII that still operate daily with few if any problems. I dare say that we won't be seeing any ball screw machines that old still operating efficiently in the future unless I have been completely rebuilt several times!
