How can CNC cutting process effectively reduce costs

As the main basic technology of manufacturing technology, with the development of manufacturing technology, NC cutting processing has also made great progress in recent years. It has entered the characteristics of developing high-speed cutting, developing new cutting processes and processing methods, and providing complete sets of technologies. New stage of development.

Luo Baihui, CEO of MouldNet and an expert member of Shenzhen Mould Technology Association, believes that new cutting processes such as dry cutting and hard cutting represented by high-speed cutting have shown many advantages and strong vitality, and have become manufacturing technologies to improve processing efficiency and quality. The main way to reduce costs.

Contemporary high-speed cutting is not a partial increase in cutting speed. It is based on the comprehensive progress and further innovation of manufacturing technology, including major advances in technologies such as CNC machine tools, tool materials, coatings, and tool structures. A multiple increase in speed can significantly improve the overall cutting efficiency of the manufacturing industry.

At present, in the process of mold processing and manufacturing, ordinary machining and electric discharge machining are mainly used. Ordinary machine tool processing mold cavities are generally roughed, semi-finished and finished before heat treatment, and then ground, polished, and time-consuming. EDM is cutting after annealing, followed by heat treatment, EDM, and finally grinding and polishing.

With the acceleration of the upgrading of consumer products, higher and higher requirements are placed on the production efficiency and manufacturing quality of molds. The shortcomings of low production efficiency and unstable quality of EDM molds are gradually exposed.

The advantages of high-speed cutting technology for machining molds are mainly reflected in:

(1) The machining efficiency has been greatly improved. Not only the machine tool has a high speed and fast feed, but also rough and fine machining can be completed at one time, which greatly improves production efficiency. Combined with numerical control technology, the mold manufacturing cycle can be shortened by about 40%.

(2) The high-speed cutting mold requires neither electrodes nor subsequent grinding and polishing, and it is easy to automate the processing process, which improves the development speed of the mold.

(3) High-speed cutting technology can be used to process hardened steel, and it can obtain high surface quality, and the surface roughness is lower than Ra0.6μm. It has achieved the processing effect of milling instead of grinding, which not only saves a lot of time, but also improves Surface quality.

To shorten the manufacturing cycle and reduce costs, mold companies must widely use advanced cutting technology, and the advent of high-speed cutting technology, which represents advanced manufacturing technology, meets the requirements and characteristics of modern mold processing.
