What are the precautions in the processing of mechanical parts？

In the daily machining process of mechanical parts , how to ensure that the parts are qualified and complete the machining of mechanical parts quickly and efficiently? Generally speaking, you can start from the following points:

    1. Before machining the mechanical parts, first review the parts drawings clearly, compare the 2D drawing files and 3D drawing files clearly, whether there is a difference, the processing standards must be clearly confirmed; then select the appropriate tool and processing equipment according to the material of the part, and different materials The equipment used for processing is different, the equipment and parameters of the tools for heavy cutting and light cutting are also different.

　　 2. Before getting on the machine, have the corresponding tools, knives, and quantities in advance, so as not to waste time looking for tools when adjusting the machine; check the operating status of the equipment, whether it is maintained, and whether the equipment is healthy to avoid working with the equipment.

　　 3. After the product adjustment is completed, the first article inspection should be carried out. The first article inspection is a full-scale inspection. The tolerance value of the inspection size is generally an intermediate tolerance, and extreme tolerances are not allowed to prevent over tolerance. Refer to the sample and drawing standards for appearance judgment. When the size and appearance requirements are met, the first piece can pass.

　　4. When the machining of mechanical parts is officially produced, the service life of the tools is counted, and the tools are regularly replaced to ensure that there will be no over-tolerance due to tool wear during the processing of parts.

　　 5. During the process of mechanical parts , after the machine is stopped due to machine problems or tool problems, the first part needs to be reconfirmed to ensure that the parts meet the drawing requirements. According to the processing time of different parts, set reasonable self-inspection and patrol inspection time to prevent batch failure of parts.

　　 6. After the machining of the mechanical parts is completed, the final inspection should be carried out on the last part, and the three inspection system for mechanical parts processing shall be implemented to prevent batch defects.

　　In the process of process of mechanical parts , once a defect occurs, the defective product must be immediately identified and isolated to prevent the part from being mixed into the next process.
