Five ways to improve precision parts processing
by：QY Precision 2020-04-01
For a hardware processing factory, whether it is in precision parts processing or automated parts processing, it is necessary to achieve high efficiency, high quality, high quality products. So how do we improve these important processes? Let's take a look! Method 1: the processing time of precision parts is shortened. For the pattern ring of a pair of tire molds, it takes 30 days to use casting technology and 20 days to use EDM technology. If the direct engraving mold with high-speed processing is used, it is generally 10 days, which can greatly reduce the processing time. Method 2: The part can be machined or finished at one time, and the processing of the corner of the pattern is flexible and changeable. Most of the tire patterns are small blocks, and there are many corners. All the patterns can be carved out with a five-axis machining center with only one clip. Method 3: due to the reduction of cutting force and cutting temperature, the tool wear is reduced and the service life is prolonged. The cost of the tool occupies a certain proportion in the cost price of the workpiece processing. Method 4: Numerical control machining can be realized by cutting instead of grinding. Replacing the grinding process with a cutting process has the advantages of simplified tool structure, strong process flexibility and energy saving, which reduce the processing cost of the workpiece. ( Introduction: Analysis of influencing factors of molding die results on production process) Method 5: compared with the conventional processing technology, the processing process can be simplified to reduce the processing cost. For example, the processing of the mold cavity, the conventional processing technology is: blank annealing-Rough machining-Quenching and tempering treatment-Semi-finishing-Electrode processing-EDM-Artificial polishing etc. With CNC machining technology, the machining process can be simplified as: blank annealing-Rough machining-Quenching and tempering treatment-Finishing-Super fine processing. This saves the processing procedure of electrode making, reduces the production cost, eliminates the surface hardening problem caused by discharge processing, and reduces or eliminates manual finishing processing. Method 6: improved processing quality. Because the excitation frequency of tool cutting is far away from the inherent frequency of the process system during numerical control machining, it will not cause forced vibration of the process system and ensure a better machining state. Since the cutting depth, cutting width and cutting force are small, the deformation of the tool and workpiece is small, the accuracy of the size is maintained, and the cutting damage layer is thinned and the residual stress is small, high precision and low roughness processing are realized. From the dynamic point of view, it can be seen that the reduction of cutting force will reduce the vibration generated by the cutting force (That is, forced vibration)Amplitude; The increase of rotating speed keeps the working frequency of the cutting system away from the inherent frequency of the machine tool and avoids resonance. Therefore, numerical control cutting can greatly reduce the roughness of the machining surface and improve the machining quality. The above information is for reference only!
