Maintenance Free CNC Machining Aluminum Bronze Bushing

Custom Metal Parts CNC Machining Different Sizes Aluminum Bronze Bushing

Bronze bushing

Generally, the Bai crankshaft of punch press is made of steel, 45 steel or 40Cr or 42CrMo. The Hb of quenching and tempering treatment is more than 250. If Du quenching treatment is used, the quenching and tempering hardness of steel Dao sleeve is about hb250. If the crankshaft is not quenched, the hardness of the two parts is almost the same, which is easy to stick and bite. In addition, it is difficult to process the oil groove of steel sleeve. Therefore, the copper sleeve is generally used as the sliding bearing of punch press. If the bearing is used, it can be used in a wide range of high-speed punch press, and the problem of copper sleeve / Bush heating cannot be solved due to the high speed of high-speed punch. In addition, the bearings of punch press are roller and needle roller bearings, and they are used in pairs, the price is higher, it can be used in high-speed punch, but it is not economical to use ordinary punch.
