Hey all, thanks for checking out the thread. I am having issues with stringy chips on ID boring/threading. Just want some other ideas from folks. Thought it would be a good discussion.
So, I am turning .875 dia. 17-4 ss on a 10hp 4 axis cnc lathe. On main side i have a 1.5 inch tapered bore. I have midigate the chip problem on that side by boring with live milling using ball EM and .030 R EM. But on sub side there is .625 deep thread with .080 relief on bottom. I am constantly needing to pull chips here. Any ideas on hot to fix this? The tolerances are all+/- .005 so it holds well. It would be nice to be able to leave the machine for more than a cycle. Free me up to attend other things. Also, I am using water dissolvable coolant and no high pressure. I rough out bore with standard bar with w style carb. insert and finish and debur thread with groover boring bar.
Thanks
