CNC high -precision processing is the main feature of precision hardware parts, and the CNC knife has a short application time. The dagger tool can significantly reduce the error of the CNC blade, thereby obtaining better surface quality, preventing repair, reducing the demand for welding wires, and shortening the time of electric spark processing. When fully considering the five -axis processing, the overall goal of using the five -axis processing mold for hardware processing must be considered: as much as possible to use very short tool processing all products, while reducing programming, clamping and processing time, but obtaining more extreme surface surfaces quality,
