Effect of machining process on motor performance
Machining mainly refers to metal cutting, that is, the machining of parts or semi-finished products with the required geometry, size and surface roughness by cutting off excess parts of the blank with a cutter. Commonly used machining methods include turning, milling, planing, grinding and drilling. The so-called machining technology is to study the dimensional accuracy, installation accuracy and surface roughness of the design requirements economically and efficiently using different machining methods. Ms. Participation today makes a simple summary of the machining process in the motor manufacturing process.
Overview of machining process of motor products
Machining is an important part of the motor manufacturing process. The matching precision, dimensional accuracy and roughness of the motor parts are mainly realized by mechanical processing means. The level of mechanical processing quality directly affects the quality grade of the motor and meets the design objectives, which has a great influence on the performance and life of the motor. . Among all the machine tools and equipment used in the mass production of small asynchronous motor manufacturers, machining equipment accounts for 40-50%, and mechanical processing accounts for about 25~30% of the total labor required to manufacture motors.
At present, the percentage of machining labor in the motor manufacturing industry is gradually decreasing. This is due to the continuous improvement of the structural structure of the parts and the increasing accuracy of the blank manufacturing, reducing the workload of machining. With the continuous improvement of the performance of metal cutting machine tools and cutting tools, as well as the use of combined machine tools, production lines or automatic production lines, the productivity of machining has been significantly improved, but this does not mean that machining process research in motor manufacturing The role played has become more marginal, and the importance of process plans and process routes has become more prominent.
Mechanical parts, such as organic seats, end caps, shafts, rotor supports, rotors, stators, bearing caps, commutators, slip rings, and base plates, housings, and bushings for large motors. How to choose the machining benchmark and processing plan to meet the technical requirements is the basic problem of machining. Here, the characteristics of several large-scale motor parts processing are discussed in detail, and the key elements and their control methods are clarified.
