In the process of punching and shearing, the shearing part of the mould and scissors of the numerical control transverse shearing machine is worn by the bearing force, heat and friction. The length of its service life and productivity level, first of all depends on the mold and scissors materials have the necessary cutting performance. In addition, the process performance of this material has a significant impact on its own manufacturing and grinding quality.

The heat treatment is good, the deformation is small, the decarburization layer is shallow, and the hardenability is better, which is an important process capability as a tool steel. Have a certain degree of welding performance, inorganic bonding ability and cutting performance. For high speed cutting tools, dies, or require good wear resistance of the tool, mold, tungsten cobalt or tungsten cobalt titanium carbide.

When the machining center can not be completed simultaneously, including the design reference, including the work of the station, the positioning datum should be as far as possible with the design benchmark coincidence. At the same time to consider the use of the positioning of the benchmark, a folder can be completed all the key parts of precision machining.
