Burr problem when cutting tungsten wire
Burr problem when cutting tungsten wire
(OP)
We are manufacturing a burner mount support out of 0.020" tungsten wire. We are cutting the material off the machine against a quill. The quill and cutoff tool is made of Tungsten Carbide 10% Cobalt. Once each part is cutoff we are finding a small burr about .003" to .005". We used Tungsten Carbide 15% cobalt and had massive tool wear and we splitting the wire. We are running about 2,500 pcs per hr. I was wondering if their is a tool steel specially made to cut tungsten wire burr free? If not I will need to invest in a different cutoff system on our machine which is big $.





RE: Burr problem when cutting tungsten wire
Splitting is a inherent defect of the W wire manufacturing process. You can get wire with a low split count, for lack of words. Check the burr on your cut and see if it's a split in the wire.
Are you using pure W or WK (potassium) wire?
