Engineering Obstacles & Our Solutions
Managing Gummy Behavior and Cosmetic Integrity in Pure Copper.
The Challenge:
Pure copper (like C101) is extremely soft and ductile. During high-speed milling, the material tends to "stick" to the cutting edges, leading to built-up edge (BUE) formation, tool breakage, micro-burrs inside deep cross-holes, and unavoidable surface scratches.
Our Solution:
We run dedicated lines utilizing mirror-polished rake tools designed specifically for non-ferrous, gummy metals. Paired with high-pressure synchronization cooling systems, we ensure immediate chip evacuation. Furthermore, all copper components undergo localized, non-marring part handling protocols from the fixture to final cleanroom packaging to avoid oxidation and cosmetic damage.
