Rough Milling Hardened steel Mold with Solid CBN Cutting Tools better wear resistance
1. Halnn Tools Rough Milling Hardened steel Mold with Solid CBN Cutting Tools better wear resistance
High-speed milling / Rough Milling of hardened steel molds is an advanced processing technology and is one of the effective hard milling technologies. For a long time, people have been using EDM to realize the processing of molds. Although EDM has process characteristics that are independent of the hardness of the workpiece, the lower material removal rate limits its range of applications. With the development of modern processing technology and the emergence of super-hard tool materials, it has become possible to perform efficient and economical mold processing by milling instead of EDM, and has achieved significant economic benefits in production.
The use of hard milling technology to process hardened steel molds not only shortens the processing cycle, but also ensures reliable processing quality. Hard milling under high-speed rotation of the spindle can obtain a surface without milling, and its surface roughness can reach Ra0.6μm.
