I’m curious what others have found for machining 6061 and 7075 aluminum metric threads 12-30mmx1.0,1.5 pitch. All OD threaded features. I’ve tried some uncoated full profile Iscar and Vargus inserts. I’m running things as fast as I can. Machine is an early 90 model Okuma LNC-8 Cadet. I get a little tearing on the threads. Some come out amazing, but not always. Will be running quantities in the 100’s to low 1000’s.
I re run the chamfer and full depth of threads in a single pass afterwards and it cleans up well. I’ve changed up the program quite a bit trying to improve machining strategy. I feel like I’ve got the best results with what I have to work with.
Looking for some options to consider trying to get better results. Will be a bar pull operation and want these to run well where I don’t have to deburr all by hand.
Thank you in advance.
