Good morning all.
I have a RFQ for 300 pcs of the part show in the pic.
The customer is asking me to quote the labor only, and he is supplying 4 each, 12' sticks of 3/16-16 allthread.
Turning the dog point, chamfering and parting off are easy....
Though, after 20+ years in the trade, I still do not know a decent strategy for chamfering preexisting threads, and NOT roll a burr into the starting thread. Once a burr is made, the only way I know to get rid of it is to spin a nut (or thread chasing die) back across the burr to remove it.
So, Practical Machinist, I ask:
What tooling or cutting strategy should be employed (in this case) to prevent a burr from being formed?
This will be run on a bar fed Genos, C axis machine.
Thank you in advance for any help you all can provide.
Doug.
