   General press crankshaft is steel parts, 45 steel or 40Cr or 42CrMo and other materials, tempering treatment HB in 250 or more, the surface if quenching treatment up to HRC45 or so, the use of steel sets, steel sets of tempering hardness of HB250 or so, if the crankshaft is not surface quenching, the hardness of the two is almost no difference between the two, easy to adhesion and bite, and in addition to the steel sets of oil groove machining difficulties.

   Therefore, the general punching machine are used as a sliding bearing copper sleeve. If the bearing is used, it is used in a wide range of high-speed punching machines, high-speed punching machines with high speed copper bushing/tile heating problem can not be solved. Another punch press bearings with roller and needle bearings and are used in pairs, the price is high, used in high-speed punch press can be, ordinary punch press with the economy is not.

    High-speed punching machine compared to ordinary punching machine, there are mainly the following aspects of difference. First of all, the stamping speed, high-speed press is usually much faster, the number of times per minute can reach hundreds or even thousands of stamping, while the ordinary press is relatively slow.
    Secondly, in terms of precision, the precision of high-speed presses is usually higher, to meet the needs of more precise parts stamping. Furthermore, the structural design and parts selection of high-speed presses pay more attention to stability and durability to adapt to the requirements of high-speed operation.
