The HSC tools specifically developed for copper processing reduce machining times, have high tool life, and produce products with the best surface qualities at the highest dimensional accuracy. This is achieved through sharp, polished, and coated tools with optimized tool geometry and specially post-treated cutting edges.
Copper has some unfavorable properties in machining, which Hufschmied addresses with the C-Razor. The high ductility and tendency to stick of the soft metal lead to built-up edge formation. This phenomenon is exacerbated by the good thermal conductivity of the material. The low heat concentration at the cutting edge can lead to cold hardening. The result of particularly stubborn material accumulations at the cutting edge are poor surface qualities and increased tool wear.
Good chip removal is therefore particularly important for a copper machining tool. Hufschmied achieves this among other things through polished chip chambers.
Parameter Recommendations
The soft structure of copper can also lead to unwanted vibrations during milling, which negatively affects dimensional accuracy. A stable machine setup is therefore essential. “When optimizing a milling process, suitable tools and wisely chosen tool paths always play a significant role alongside the cutting parameters. Given the described properties of the material, this is particularly true for copper. Therefore, we also provide recommendations for cutting speed, feed rate, and cutting depth with the C-Razor,” explains Christel Hufschmied, Managing Director of Hufschmied Zerspanungssysteme GmbH.
The C-Razor tool family for copper electrode production includes torus mills and ball mills with diameters from 0.3 to 12 mm.
