Analysis of the Reasons Affecting the Machining Accuracy of Motor Shell

We all know that the motor housing can protect the motor from pollutants in the operating environment. With the development of society and technology, the market has increasingly higher requirements for the motor housing. Manufacturers should improve the processing accuracy requirements when processing. To better meet customer needs. Precision, various motor housings, motor housings, etc. can be customized. Next, the author will briefly analyze the reasons that affect the machining accuracy of the motor housing. 1. The error in principle. The so-called principle error is the error caused during the forming activity processing. 2. There are errors in tool and fixture manufacturing. Fixtures and tools have a very wide range of uses in actual industrial applications. However, in the actual machining process, fixtures and tools will also have a great impact on the machining accuracy of the motor housing. 3. During the machining process, because the barrel parts are thin-walled sleeve parts, the clamping rigidity and machining rigidity are both poor, and vibration is prone to cause part of the size to be out of tolerance; 4. The machine tool cooling system malfunctions, resulting in continuous workpiece processing. High temperature, resulting in thermal deformation; 5. There are problems with the spindle bearing of the machine tool, and the vibration is severe, which affects the dimensional accuracy; 6. The depth of the inner hole is long, the extension length of the inner hole tool is too long, and the inner hole surface appears without proper clamping system Vibration marks and so on. 7. The wear error of the machine tool. When the machine tool is used for machining, the machine tool will be worn for a long time, especially the tool of the machine tool, after a long time of parts cutting, the wear is also very serious. After the tool is worn, the relative installation position on the machine tool will change, and the motor housing parts processed from this will have some errors in shape and size.
