Problems solved by technology

[0002] At present, with the rapid development of the machining industry, a large number of workpieces need to be processed. Because the cutting tools are vulnerable items, the consumption is very large, and the cost of the cutting tools is high, especially the cutting tools of some special materials. The production cost is huge, and the existing tools have low strength, fast wear, short service life and easy breakage, which cannot meet the existing market demand
