In the production of high-speed precision punch, we only have to frame the metal coil which must be pressed and adjust the stamping rate to be prepared, then we can completely and easily wait for the commodity to be produced. So what principle makes the high-speed precision punch so intimate?

In addition, the deformation of materials in the high-speed stamping process is caused by the high-speed stamping machine and the metal forming process. Therefore, it is necessary to use lubricants to produce a kind of strong and heat-resistant film which adheres to the metal surface and separates the workpiece from the mold. Then reduce the friction between the metal and the mold, release heat and improve the mold life, improve the precision of the workpiece and stabilize the quality of the workpiece.

In foreign countries, there are fixed grease for fine blanking of different materials. With the development of high-speed precision punch to the direction of thick and fine, it is required to develop high-quality lubricants with heat resistance and high pressure resistance. In China, the application of fine blanking technology is more and more extensive, and the development of fine blanking lubricant is also improved. At the present stage, the key method to evaluate the quality of lubricants at home and abroad is based on the actual production and application results, that is, the surface smoothness and burr height of the commodity shall meet the production requirements, and the number of punching pieces after one-time grinding of the mould shall be considered. For medium carbon steel plate, the maximum number of pieces that can be punched after one cutting edge of die is 20000-40000 pieces.

Our country has digested and absorbed the foreign excellent technology in the equipment and process of high-speed precision punch press, and is close to the international high level step by step in the sustained, stable and rapid development.
