Hi everyone,
We machine tensile bars out of precut Aluminum stock on a Mazak QT250. I machine the first thread and profile/gage section first then flip the part. However the problem that has arisen is once I flip the part to cut the threads, the chuck jaws crush /compress the first threads that I have made. i tried turning down the pressure of the jaws but if I get too low, the tool starts moving the part inside ever so slowly. Current jaws are the standard stainless.
Any advice on which jaws to use, another method of clamping the parts or any other ideas?
