I am having trouble machining 5/16-24 threads in this material. They are thru threads, approx. .375 flange thickness. We are using an emuge threadmill. We drill thru with an iscar cam drill, chf the hole, finish the minor dia to the top of the tolerance with a carb end mill, then we threadmill. We also come back in with deburring passes with all tools. We maybe get a couple of holes to size, then we end up having to hand tap.
We are in a Haas machine, holding the part very rigid in a kurt vise. Any suggestions would be great, Thanks!!
