only engage 10% to 15% of the cutter cutting edge to allow it to cool The trick here is to do the RPM's per the cutters diameter and composition, which determines the surface feet. Then you can go fast as feed will permit and or finish requirement allows. However, only engage 10% to 15% of...

Having done OEM work on many brands, I've walked into factories and seen first hand what a disappointment some of these no names are. Bell Helicopter was experiencing viabration/chatter, which their old Monarch never gave. cheap Jets flinging oil from the spindle. Back then these old lathes...

Lets see a made in China manual machine and a British manual machine? Seeing that the Clausing has a history, I would opt for it. However, there isn't anything as good (in my opinion)as the old, not made any longer, Monarch lathe of yesteryear.

HAAS will shut it off as you go to tool change. Even during set up, when your aiming the coolant and are in a rotate forward/rotate reverse, it shuts off and then back on upon tool rotation. High pressure through the spindle is an entirely different M-code and would be a seals issue in leaving...

However, we did develope a post which was Unigraphics (EIA/ISO) dependent. However, its been eons and I doubt that much would match. The machine...

I have found that decisions you make can come back to haunt you. If you create a post for a machine/machines you may likely have to update old programs. Then industry standards on modular tooling and the hole patern you elect to use are carved in stone. These issues, and others, need to be...
