Advantages of high speed cutting for mold processing
As an important process equipment, molds play an important role in the industrial sectors such as consumer goods, electrical appliances, automobiles, and aircraft manufacturing. Improving the level and quality of mold production technology is an important factor in the development of China's mold manufacturing industry. Because the high-speed cutting technology of the mold can significantly improve the mold production efficiency and mold precision and service life, it is gradually replacing the EDM finishing mold, and has been widely adopted by foreign mold manufacturers, becoming a major trend in mold manufacturing. Advantages of high speed cutting for mold processing Mold processing is characterized by a single piece of small batch size and complex geometry, so the processing cycle is long and the production efficiency is low. In the traditional mold processing process, the finishing hardened mold usually adopts the electric discharge machining and the manual polishing process, and the post-processing takes a lot of time. Shortening processing time and reducing production costs are the main goals of developing mold processing technology. Mould expert Luo Baihui said that in recent years, there have been many new technologies in the mold processing technology, such as high-speed cutting, CAD/CAE design simulation, rapid prototyping, EDM milling and composite processing, among which the most eye-catching and effective. The best is high speed machining. The high-speed machining mold uses the high-speed and high-feed speed of the machine tool to complete multiple production steps of the mold in a cutting manner. The superiority of high-speed machining molds is mainly reflected in the following aspects: 1 High-speed cutting roughing and semi-finishing, greatly improving the metal removal rate. 2 High-speed cutting machine tools, tools and processes can be used to process hardened materials. For small molds, after heat treatment of materials, coarse and fine processing can be completed in one setup; for large molds, roughing and semi-finishing before heat treatment, and hardening and finishing after heat treatment. 3 high-speed high-precision hard cutting instead of finishing, reducing a lot of time-consuming manual grinding, improving efficiency by 50% than EDM. 4 Hard cutting process the final forming surface to improve surface quality and shape accuracy (not only low surface roughness, but also high surface brightness), which is more advantageous for mold processing of complex curved surfaces. 5 Avoid the decarburization, burn and micro-crack phenomenon caused by electric spark and grinding, greatly reduce the surface damage after the mold finishing, and improve the mold life by 20%. 6 The workpiece has less heat, less cutting force and less thermal deformation. It is combined with CAD/CAM technology for fast machining of electrodes, especially for electrodes with complex shapes and thin walls. The advantage of high-speed cutting is self-evident for mold processing, but at the same time, the high-speed cutting cost of the mold is high, the use of the tool is high, and complicated computer programming technology is required for support and equipment operation cost. High, therefore, due to capital, technology and other reasons, the domestic application of high-speed cutting molds is still not much. At present, there is a need to solve the problem of how to select and apply high-speed machining molds, high-speed cutting tools, reasonable machining processes, tool paths. A series of problems such as programming layers and process experiments. Full Color Series-Color HUAKAI FENGSHI TECHNOLOGY (CHONGQING) CO., LTD. , https://www.cqhkpvb.com
