Micromilling of hardened materials-flexible and economic production of components for micro systems by cutting

摘要

The use of ultra-fine-grain cemented carbide end mills for micromilling allows the flexible and economic production of micro system components in small-lot or single-piece fabrication. Solid carbides as cutting tool material make it possible tomachine steel-materials for applications in micro system technologies. A correct selection of feed, cutting speed, depth of cut and milling strategy is necessary to open up this production technology suitable for machining of hardened steel.
