In the processing of the equipment shell, in order to avoid surface scratches, the following points need to be paid attention to: (1) Select appropriate materials: · Select materials with moderate hardness and high surface finish to reduce scratches caused by material characteristics during machining. (2) Optimize the machining process: · Reasonably arrange the machining process, minimize the number of handling and turning of the workpiece during machining, and reduce the risk of scratches. · Adopt appropriate machining methods and parameters, such as controlling the cutting speed, feed and cutting depth, etc., to avoid scratches caused by excessive cutting force. · For precision machining or critical surfaces, soft tools or abrasives can be used to reduce damage to the surface of the workpiece. (3) Protect the surface of the workpiece: · During the processing, use suitable fixtures and support devices to ensure that the workpiece is stable and does not shake, and avoid collisions with machine tools or other tools. · Cover the surface of the workpiece with a protective film or soft material, such as felt cloth, insulating fabric, etc., to reduce the risk of friction and scratches between the workpiece and other objects. (4) Improve the skill level of the operator: · Strengthen the training and guidance of the operator, improve their skill level and safety awareness, so that they can master the processing skills and avoid scratches caused by human factors. · Require the operator to strictly abide by the operating procedures during the processing, pay attention to details and precision control, and ensure the quality of processing. (5) Strengthen equipment maintenance and upkeep: · Regularly carry out maintenance and upkeep of processing equipment to ensure that the equipment is in good working condition and avoid processing errors and scratches caused by equipment failure. · Regularly clean the surface and interior of the equipment to remove oil, dust and other impurities and keep the equipment clean and tidy. (6) Take protective measures: · Set up protective measures in the processing area, such as protective cover, protective net, etc., to avoid scratches caused by collision between external objects and the workpiece. · Use auxiliary materials such as coolant or lubricant during processing to reduce the risk of friction and scratches on the surface of the workpiece. Through the implementation of the above measures, surface scratches during the processing of the equipment shell can be effectively avoided, and the processing quality and the overall quality of the product can be improved.
