Numerous advantages: Hard machining with a geometrically defined cutting edge in combination with CBN has numerous advantages over grinding . High metal removal rates are possible with this process, which results in shorter machining times. Conventional machines may be used. This offers the possibility of complete machining of the component. Even complex contours can be easily produced on a lathe. With grinding, on the other hand, the wheels have to be elaborately profiled. The high surface quality that can be achieved with hard turning also saves on further grinding operations.
In hard milling, solid carbide end mills with a special coating demonstrate high milling performance.
For milling hardened steels with solid carbide end mills, Horn developed a special milling cutter programme for the DS milling system. A special geometry ensures high milling performance from 50 to 70 HRC. In conjunction with the special TS3E coating, the tools offer long tool life due to the high maximum operating temperature. HORN has acquired a high level of expertise in the coating of precision tools. Horn engineers are constantly researching and developing new and existing coatings, always with the aim of making them even more efficient. A coating thickness of only a few μm can increase the service life of solid carbide tools by up to 1,000 percent or more.
