Hi guys,
We are currently looking into doing a job that requires a 60 deg. angle to be machined on the end of 1 1/4" dia. and 1 1/2" dia. cold rolled bar stock. We have done small quantities on a manual lathe, but the customer is talking much larger quantities now.
Our idea to speed up the job was to machine soft jaws and run numerous parts at a time in our CNC mill (we don't have a CNC lathe). We purchased a "face angle shank" mill from MSC for our test runs, but got mixed results. We are able to do the job, but we get quite a bit of chatter. There is only 0.75" of material protruding out of the jaws and we have varied the speeds, feeds and cut depths. We have a feeling it may be the tool causing the issues as it is a straight flute light weight mill (HSS).
Does anyone have any ideas on a more robust tool capable of machining steel? Is there a better tool other than a "face angle shank" mill for the job? Thanks for any suggestions.
Mike
