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 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.
