A motor shaft manufacturer with strong processing capabilities often has strict production standards and strict requirements for product quality control. Therefore, the following points are often paid attention to when processing the motor shaft:
Generally, high-quality precision motor shafts are particular about the use of raw materials, and high-quality alloy steels (such as 45#steel, 55#steel) are selected. Good raw materials have excellent compressive strength and bending rigidity, and can Digital display high speed ratio, small torque. If 45# steel is used as the raw material of the motor shaft, no heat treatment is performed in the middle and late stages, which can also meet the requirements of physical properties.
At present, precision motor shafts can be divided into two categories: optical shafts and web shafts. The specific needs to be determined according to the size of the rotor hole shaft, but the optical shaft and the spoke shaft are basically the same in terms of processing technology. Transformer core files And transformer core milling processing is required to refer to H7/k6.
Of course, during the machining process, the torque borne by the motor shaft rotor can be obtained according to calculations. In order to make the shaft extension end of the motor shaft match the position of the socket required by the customer, the shaft extension end needs to be finely polished. The purpose of fine polishing also includes making the motor shaft and the coupling have a good area of contact, so that the force it bears can be evenly distributed, and the shaft extension end becomes more beautiful.
The keyway of the motor shaft should be processed by a milling machine. Generally speaking, the machining process of the precision motor shaft can be divided into: fine turning, centering and boring, outflow cutting part, and cutting.
Nowadays, many precision motor shafts are processed by CNC lathes, which greatly improves the accuracy of product processing and also effectively increases the output. However, in the equipment investment, only those equipment with complete performance and stable operation can produce high Quality products.
