What are the types of processing order of precision mechanical parts

Each processing method has its processing sequence. Our operators need to process according to their processing sequence, but cannot process at will, which will have a certain impact on processed products or quality problems. Precision machining is one of them. What is the order of machining precision mechanical parts? Let Hongao Machinery tell us. The processing of finishing parts must be based on the structure of the parts and the condition of the blanks, as well as the requirements of positioning and clamping. The focus is that the rigidity of the workpiece is not destroyed. 1 How the previous process is processed will not affect the positioning and clamping of the next process. The middle cross section has a general fine part processing process.

2 First stop the adding process of the inner cavity, and then stop the shape processing process.

3 It is better to use the same positioning, clamping method or the same tool stop process to reduce the number of repeated positioning, the number of tool changes and the number of moving pressure plates. Shenzhen Machining 4 In the multiple processes stopped in the same device, the process of destroying the rigidity of the workpiece should be arranged first.

Second, the tool concentration sequence method is to divide the entire process according to the tools used by the precision machining manufacturers, and all parts on the parts can be completed by using the same tool. Use other tools to successfully complete other parts that can be completed. This can reduce the number of tool changes, shorten the dead time, and reduce unnecessary positioning errors.

, Processing part sorting method Regarding parts with a large amount of processing content, according to their structural characteristics, the processing parts can be partially red, such as internal shapes, shapes, curved surfaces or planes. Ordinary processing planes, positioning surfaces, post-processing holes, first process simple geometric shapes, and then process complex geometric shapes. First, process parts with lower precision and process zero with higher precision.
