An Upstate New York contract machining company that works with copper.
There were issues creating a thread in the part. Drills were "loading" with chips and breaking. Taps were "tearing" threads and at times, breaking.
An H&C Application Engineer suggested coating some tools with "CRN" to reduce edge buildup on the tooling. Testing was done to prove out new tooling.
Significant improvement in quality of pre-tapped holes and threads. Reduced tooling issues and tooling use. 5 to 1 tool life increase with drills. 8 to 1 toll life increase with taps. Resulting in an overall reduction of machine time, tooling costs and an increase in productivity.
