Dongguan cnc processing plant to share with you: the advantages of high-speed cutting
Reduce the heat generated by cutting
Dongguan cnc processing plant Because the milling machine spindle rotates at a high speed, the cutting process is shallow cutting, and the feed speed is very fast. The contact length and contact time between the cutting edge and the workpiece are very short, which reduces the heat conduction between the cutting edge and the workpiece. High-speed cutting adopts dry milling or oil-gas (oil mist) lubrication system, which avoids the disadvantage of a large amount of heat generated at the contact between the tool and the workpiece during traditional machining, ensures that the tool works under low temperature conditions, and prolongs the service life of the tool.
Machining is conducive to the processing of thin-walled parts. The cutting force during high-speed cutting is small, and it has high stability. The high quality of processing may be very good compared with the internal staff of the company, but compared with the employees of other companies. Performance may not be considered excellent. As far as China is concerned, it is simple and effective for us to use benchmarking to determine employee training needs. This kind of learning benchmark object can be external or a combination of internal and external. First of all, we must clarify the development strategy of the enterprise. The Dongguan cnc processing plant clarifies the company's future development goals and business priorities through analysis of the company's internal and external environment and organizational resources. According to the development strategy of the enterprise, we will look for benchmarking companies that can be compared, and finally determine the benchmarking companies through comparative analysis. After determining the benchmarking company, one item is to understand its development strategy, its market share and market growth rate, or the situation of its employees in various aspects, etc. This should be determined according to the actual situation of the company. Because enterprises are in different development periods, their focus is different, that is, the focus of material resources, human resources and financial resources that enterprises need to invest is different. Therefore, within a certain period of time, companies must accurately select the departments and positions they compare with benchmark companies. This is more practical, because benchmark companies are not good everywhere, and there is little practical significance for comparison in some aspects. In this way, the limited resources of the enterprise can be used more fully. After determining the benchmark company, and then comparing the corresponding departments and employees of the company with the benchmark company, you can find the gap between the two in work performance, compare and analyze, find the reasons, and finally determine the training needs based on the actual situation of the company. Training is costly. If there is no effective way to determine whether the company needs training and training methods, but blindly conduct training, such training is difficult to achieve the expected results. There is a difference between comparisons. This training analysis model is simple and practical and can partially replace certain processes, such as EDM and grinding.
One of the major features of high-speed machining is that high-speed cutting can machine parts with hardness up to HRC60. Coated hard alloy cutting tools are used to process the mold, and the hardened tool steel is directly installed and processed at one time, which effectively avoids the clamping error caused by multiple installations of the parts, and improves the geometric position accuracy of the parts. In the traditional process of processing molds, the workpiece after heat treatment and hardening needs to be processed by EDM, and high-speed cutting is used to replace traditional cutting processing methods. EDM in the mold manufacturing process can be omitted, and the processing technology and investment cost are simplified. . High-speed milling can be carried out on a dedicated CNC machine tool or machining center, or on an ordinary machine tool equipped with a high-speed spindle. The latter not only has the processing capabilities of ordinary machine tools, but also can perform high-speed milling, which reduces equipment investment and increases the flexibility of machine tools. High-speed cutting can improve machining efficiency, quality, and process simplification, and increase machine tool investment, tool investment and maintenance costs, but a comprehensive comparison can significantly improve economic benefits.
