In the production, if rust is found in the assembled motor parts, rust removal treatment should be carried outYLJTorque motor manufacturers in the process of product rust removal is how to carry out, the following is a simple understanding with Senli Motor Xiaobian.

       Mechanical rust removal method is the use of machinery and some simple tools to eliminate rust spots under the action of force. When the rust layer is relatively shallow, emery cloth can be used for grinding, and an emery cloth of appropriate thickness should be selected according to the surface roughness required by the parts to be polished, so as not to destroy the due accuracy.

       When grinding with emery cloth, the direction of grinding should be as consistent as possible with the direction of the original processing turning. For parts with high dimensional accuracy requirements, such as the diameter of shaft extension and bearing stop, attention should be paid to the control of grinding amount to prevent waste caused by excessive grinding amount exceeding the range allowed by size or shape and position tolerances.  If the rust layer is thick and the shape is complex, it is not suitable to use simple tools such as sandpaper to remove it. Meanwhile, if the size of the parts is not strict, you can use tools such as scraper, file, and grinding wheel to clean them according to the situation.

       The method of using a liquid "rust remover" to apply to the rust part and remove the rust under chemical action is called chemical rust removal method. The advantage of this method is that it has little effect on the dimensional accuracy of the treated parts and is relatively labor-saving, but it is limited to the shallow rust layer, and some parts will lose the original gold luster after rust removal due to chemical reaction.
