Due to mold processing features is single and small batch, complex geometry.thus processing cycle is long, low 
productivity.In the conventional mold process, finishing crushed hard tooling commonly used EDM and artificial light repair process, spent a lot of time in later processing.Shorten the processing time and reduce production costs is the main goal of the development of mold processing technology.
In recent years, mold processing technology with many new technologies, such as high-speed cutting, CAD / CAE design and simulation, rapid prototyping tooling, molding and EDM milling complex processing, the best one is high-speed machining.
Mold is the use of high-speed machining tool as high speed and high feed rate, cutting the way to complete the mold of multiple production processes. Advantages of high-speed machining of mold mainly in the following areas:
1.High-speed cutting roughing and semi-finishing, increase metal removal rates.
2.High-speed cutting machines,tools and processes, machining hardened material. For small mold, in the material after heat treatment, roughing and finishing can be completed in one clamping, for large die,do roughing and
semi-finishing before heat treatment, finishing after hardening heat treatment.
3.High-speed precision cutting instead of hard finishing, reduce the amount of time-consuming manual grinding, the
efficiency higher 50% than EDM.
4.Hard machining the final shape,improve surface quality for complex surface mold processing.
5.Avoid sparks and grinding decarbonization produced, burns and micro cracks, greatly reducing the mold after finishing table damage, improve the mold life to 20%.
6.Workpiece less heat, reduce cutting forces, heat distortion, combined with CAD / CAM technology for fast
processing of the electrodes, in particular complex shape, thin-walled easily deformable electrode.
