The plum coupling is a kind of high-speed miniature coupling in the pin coupling. Because of its simple processing technology and low price, it is deeply loved by the majority of customers.Whether the plum blossom coupling needs to be processed by a precision machine tool depends mainly on the working environment in which it is used.If the speed of the coupling is too high, it is necessary to use a precision machine tool to process the coupling.The main reason is that too high speed will cause the coupling elastic body to heat up. Because the size of the coupling plum claws processed by precision machine tools is evenly divided, the elastic body is heated evenly, so the service life of the coupling will be greatly increased.If it is a coupling processed by an ordinary machine tool, the plum blossom claw of the coupling will appear uneven and uneven, which will cause uneven heating of the elastic body, thereby reducing the service life of the coupling.

　　The plum coupling is processed by machining methods such as turning, milling, and broaching, and then undergoes overall heat treatment.In order to ensure sufficient mechanical strength, there is another type of claw plate on the market that is a casting, which can be produced in large quantities without processing loss.So the price is much lower than machining. But the performance of castings is not very good.It is better not to use it in some important occasions.In addition, the claws of the casting are prone to tapping (the claws fall off) under high speed or high load.
