Problems solved by technology
[0002] When the motor is in use, it must obtain a large output torque on the shaft, and the space outside the shaft is strictly limited. It is difficult to set the arm in the slender space, which reduces the mechanical efficiency. At the same time, the motor shaft needs to be perforated because of the lead wire. The bearing capacity is relatively weak, which weakens the mechanical strength
In addition, in the production process, due to the need to use external machinery to perform operations such as milling, cutting, and drilling on the motor shaft, it is easy to affect the strength of the motor shaft, thereby destroying the internal structure of the motor shaft and shortening the use of the motor shaft. life
In addition, in the process of processing, various parts that are difficult to process are often encountered, thereby reducing the processing efficiency, wasting a lot of manpower and material resources, and the work effect is poor.

Embodiment Construction
[0016] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0017] A machining process for a motor shaft, comprising the steps of:
[0018] 1) Rough machining by milling: First, the raw material is cut off a large amount of surplus material by milling, and processed into blanks by dividing them into different amounts, leaving a small amount of margin;
[0019] 2) Heat treatment: After that, put the blank into the furnace, slowly heat up for a period of time and reach 450°C, and then heat it to about 700°C at a heating rate of 120°C per hour, and keep the temperature difference of each area in the furnace during the heating process. If the temperature is higher than 30°C, keep warm in the furnace for 4-6 hours, and finally cool down to 200°C at a cooling rate of 50°C / hour in the closed furnace;
[0020] 3) Form grinding: the blank is clamped on the grinding fixture, and the desired shape is obtained by...
