CNC machined parts may have scratches due to various reasons during processing. To avoid this situation, you can start with the following aspects:
Select the correct cutting tool: Be sure to use the appropriate cutting tool, including tool material, edge geometry, and cutting conditions. Select cutting tools appropriate for the workpiece material to reduce the risk of scratches.
Control feed and cutting speed: Adjust the feed speed and cutting speed appropriately to avoid excessive cutting force caused by excessive feed speed and amount, which may cause scratches.
Use coolant or lubricant. Using cutting fluid or lubricant during machining can reduce cutting temperature, reduce cutting force and friction, and help avoid scratches.
Optimize the machining path: Plan the machining path wisely to avoid unnecessary movement and collision of the tool with the workpiece surface, thereby reducing the likelihood of scratches.
Keep the workbench and fixtures clean: Make sure that the surfaces of the workbench and fixtures are clean and free of dirt to avoid scratches due to the presence of impurities or particles during processing.
Regularly inspect and maintain equipment: Regularly check the wear of key components such as cutting tools, fixtures and transmission systems of CNC machines, and promptly replace or repair them to ensure normal operation and precision machining of equipment. .
Operational characteristics: Operators must be familiar with the operating procedures and machining procedures of CNC machine tools and operate in strict accordance with the requirements to avoid scratches caused by improper operation or misuse.
