The machining accuracy of motor parts is one of the important factors affecting the performance and life of the motor. In the manufacturing process of motor parts, grasping the machining accuracy is critical to improving motor performance, reducing noise, extending service life and improving product quality. This article will elaborate on the definition, influencing factors and control methods of machining accuracy.

1. Definition and influencing factors of machining accuracy

Processing accuracy refers to the degree of deviation between the workpiece and the equipment standards or design requirements during the processing process. For motor parts, the processing accuracy directly affects the performance and life of the motor. The main influencing factors include the following aspects:

1. Material selection: Material selection has an important impact on processing accuracy. Different materials have different deformation and thermal expansion and contraction coefficients during processing, and the requirements for dimensional stability and dimensional accuracy of parts are also different. Materials should be selected reasonably based on the working conditions and requirements of the motor.

2. Processing technology: Processing technology is the decisive factor in the processing accuracy of motor parts. Processing technology includes cutting technology, heat treatment technology, surface treatment technology, etc. Different processing techniques have different effects on dimensional control, surface quality and mechanical properties, and need to be selected and controlled according to specific requirements.

3. Equipment and tools: The accuracy, rigidity and stability of processing equipment and tools have a direct impact on processing accuracy. The higher the precision of equipment and tools, the higher the precision of parts can be processed.

4. Processing technology control methods: Processing technology control methods include manual processing, semi-automatic processing and fully automatic processing. Manual processing accuracy is greatly affected by the operator's skill level and experience, while automatic processing can effectively improve processing accuracy.

2. Control method of machining accuracy

In order to ensure the processing accuracy of motor parts, a series of control methods need to be adopted. The following will introduce in detail aspects such as quality control, process improvement and testing methods.

1.Quality control

Quality control is one of the important means to ensure processing accuracy. A sound quality control system should be established, including quality control of raw materials, processing techniques, equipment and tools. In every processing link, strict quality inspections are carried out to ensure that the processing accuracy meets the requirements. At the same time, detailed quality inspection specifications and standards should be formulated to deal with unqualified products in a timely manner.

2. Process improvement

Process improvement is the key to improving processing accuracy. Through process improvement, error factors can be reduced, processing efficiency improved, and costs reduced. During the processing of motor parts, the following methods can be used to improve the process:

(1) Optimize the processing procedures and sequences, reduce the number of procedures, and avoid errors caused by multiple clamping and positioning.

(2) Select reasonable cutting parameters to ensure cutting quality and processing accuracy.

(3) Choose appropriate processing tooling and fixtures to improve positioning and clamping accuracy.

(4) Use modern CNC processing technology to improve processing accuracy and stability.

3. Detection means

For the control of processing accuracy, we must rely on reliable detection methods. Common detection methods include three-dimensional coordinate measuring machines, projectors, metallographic microscopes, surface roughness meters, etc. By testing motor parts, problems in processing can be discovered and corrected in a timely manner to ensure processing accuracy.

At the same time, statistical analysis methods can also be used to analyze and control errors during the processing process. By conducting statistical analysis on a certain number of samples, the distribution pattern of errors can be obtained, thereby optimizing the processing technology and improving processing accuracy.

3. Summary

The machining accuracy of motor parts is one of the key factors to ensure the performance and life of the motor. To grasp the machining accuracy of motor parts, it is necessary to comprehensively consider and optimize aspects such as material selection, processing technology, equipment and tools, and processing technology control methods. During the processing process, a sound quality control system must be established and strict quality inspections must be conducted to ensure that the processing accuracy meets the requirements. At the same time, through process improvement and the use of modern detection methods, processing accuracy and stability can be improved.

Finally, improving the processing accuracy of motor parts requires continuous exploration and innovation. Motor manufacturing companies need to strengthen cooperation with scientific research institutions and universities, increase investment in R&D, improve technical levels, and continuously promote the development of the motor manufacturing industry.
