Application of high speed machining skills in machine tool mold industry
Driven by the continuous growth of processing tools, cnc systems, CNC tools and other related skills, with the rapid development of processing and manufacturing, high-speed machining skills have been increasingly used in the processing and manufacturing of machine tools and molds.
High-speed cutting causes great changes in the quality of the cutting process. The metal removal rate per unit power is improved by 30%~40%, the cutting force is reduced by 30%, the cutting life of the tool is improved by 70%, and the cutting heat left on the workpiece is large. The amplitude is low and the low-order cutting vibration almost disappears. With the advancement of the cutting rate, the removal rate of the blank material per unit time has increased, the cutting time has been reduced, and the processing effect has been improved, thereby shrinking the manufacturing cycle of the product and improving the market competitiveness of the product.
Cnc high-speed cutting plus labor is one of the most pressing advances in the mold industry: manufacturing skills are advanced manufacturing skills that combine efficiency, quality and low cost. Compared with the boring cutting process, the cutting rate and feed rate have been greatly improved, and the cutting mechanism is not the same.
The small amount of fast forward machining at high speed cuts the cutting force, and the high speed displacement of the chip reduces the cutting force and thermal stress deformation of the workpiece, and improves the rigidity difference and the probabilities of the cutting process of thin-walled parts. Due to the low cutting force, the advancement of the rotational speed makes the cutting system's labor frequency far from the low-order natural frequency of the machine tool, and the workpiece roughness is the most agile to the low-order frequency, thereby lowering the appearance roughness.
In the processing of high-hardened steel parts (HRC45~HRC65) of the mold, high-speed cutting can replace the steps of electric machining and grinding and polishing, thereby prohibiting the manufacture of electrodes and time-consuming electrical processing, and greatly reducing the fitter's work. Grinding and polishing amount. High-speed milling can also be successfully completed for some thin-walled mold parts that are increasingly necessary in the market, and in the center of high-speed milling CNC machining, the mold can be multi-step machining in one clamping.
The high-speed machining skills have a great impact on the machine tool and mold processing technology, changing the boring process of annealing, milling, heat treatment, grinding or electric pulse processing, manual grinding, polishing, etc., and even high-speed cutting. Processing and replacement of all the original processes.
High-speed machining skills can be applied to direct machining of hardened mold cavities (especially semi-finishing and finishing), and have been widely used in EDM electrode processing and rapid prototyping. Mass production practice proves that the application of high-speed cutting skills can reduce the manual grinding time of about 80% of the subsequent processing of the mold, saving about 30% of the cost of adding people, the machining accuracy of the mold appearance can reach 1m, and the cutting effect of the tool can be doubled.
