Summary of the technological process and precautions of CNC machining of hardware parts As we all know, CNC machining is suitable for hand model making and small batch production, and various types of spare parts are processed in large quantities. The precision of CNC machining parts is the highest in the machinery manufacturing industry and can serve in Processing of precision parts with high precision requirements in various industries.

　　So, what is the CNC machining process of hardware parts? Here, based on years of technical experience in the industry, Guowei Precision summarizes the workflow of CNC machining.

　　The process sequence of CNC machining, first of all, before CNC machining, you must clearly see the process flow contained in the machining drawings, and clearly know the parts, shapes, dimensions of the drawings and the processing content of the next process. Write the drawings that need to be processed into the program, and then connect the computer to the CNC machine tool, and command the CNC machine tool to operate and process through programming, and process rapid prototyping parts.

　　After rough machining is completed, self-inspection should be carried out in time, so as to adjust the data with errors in time. Finishing is carried out after the parts have been confirmed by rough machining. After finishing machining, workers should carry out self-inspection of the shape and size of the processed part. After the self-inspection of the workpiece is completed, the workpiece can be removed and sent to the inspector for special inspection after confirming that it meets the drawings and process requirements. When small batch processing is required, batch processing can only be carried out after the first hand model is confirmed to be qualified.

　　There are many points that need to be paid attention to during the entire processing process, otherwise it is easy to cause parts to be scrapped. Fengrui Model summarizes the most noteworthy items:

　　1. Whether the processing technology of parts is correct or not;

　　2. Whether there is looseness during the processing of mechanical parts;

　　3. The positional dimension between the processing surfaces. The basic length and width dimensions of the vertical surface are measured, and the base point dimensions marked on the measurement drawing of the inclined surface. After checking the size of the position, measure the rough shape ruler (except the arc);

　　4. The orientation scale of the processing surface. Whether the dimension from the processing surface of the part to the reference edge (reference point) meets the drawing requirements;

　　5. Before clamping the workpiece, measure whether the size of the blank meets the requirements of the drawing. When clamping the workpiece, carefully check whether its placement is consistent with the programming instructions
