The existing processing equipment used in the tool processing industry is mainly domestic equipment with limited processing capacity of some procedures, and the processing process of one tool can be finished only by using a plurality of machine tools, so that the product cost is invisibly improved, the tool is clamped and processed for a plurality of times, and the processing precision of the tool is limited; the adoption of imported high-end equipment is high in cost, and the requirement on the quality of operators is correspondingly high. Thus, many of the high-end equipment is imported to meet the market demand.

With the rapid development of modern manufacturing industry, customers must pursue high quality and high stability products. For this reason, difficult-to-machine materials, such as special alloy materials, composite materials, or a combination of both, have been increasingly used in new generation products. For example, in the IT industry, the processing of housings for many electronic products has progressed from conventional injection molding to the processing of monolithic alloy housings and even composite materials such as carbon fibers. This means that the manufacturers of machining tools have made more demands, and the development of tools will be greatly changed.
