Precision press machine is an advanced precision forming machine that adopts plastic processing and cutting art. In one punching or forming process, parts with high dimensional accuracy, good shear surface smoothness, and a certain three-dimensional shape can be obtained. It has the characteristics of low consumption and wide application.
The dimensional tolerance of precision punched parts can reach T7-T8 level accuracy, and the roughness of the shear surface can reach Rao 0.8-0.4 μ m。
For many complex shaped parts, such as gears, sprockets, cams, and other flat parts, a single precision punching process can be completed in just a few seconds, reducing a large number of cutting processes such as milling, planing, grinding, and boring, and improving efficiency by more than 10 times.
The precision punching process not only saves a large amount of energy consumption in cutting machines, but also has a strong cold work hardening effect on the surface after precision punching, sometimes replacing the quenching process in the subsequent process.
