The first is the innovation of material grades, which accounts for a large proportion of the current cemented carbide tool innovation, especially large comprehensive companies with the development and production capabilities of cemented carbide and superhard materials. These companies launch a large number of new grades every year. Become the main selling point of their new knife products. The development idea is to integrate the advantages of materials, coatings, and grooves based on the characteristics of the application field, and develop the blade according to the right medicine, so that the blade can show performance advantages in a certain application range and produce good processing results. , generally can improve processing efficiency by more than 20%. It can also be seen that we must speed up the construction process of cemented carbide R&D and production bases.

The second is that coatings play a big role in tool innovation. Since coating technology entered the field of tool application, the coating technology of cutting tools has developed very rapidly. As innovation and development of coating processes, equipment, and ingredients continue to accelerate, its ability to modify cutting tools is also increasing. Due to the coating technology’s significant effect on improving the performance of the cutting tools, the flexibility of the process, and the rapid development of new grades, it not only greatly improves the cutting performance of the cutting tools, but also enables the innovation of blade coating grades. Fast and good. Coating has become the most important factor in promoting the progress of cutting technology. So far, our country does not have the ability to independently develop tool coating equipment and processes, which has restricted the progress of our country’s cutting technology and the innovation of coating brands. Vigorously developing tool coating technology is a top priority.

The third is that the innovation of tool structure has strong momentum and shows great potential. We once had a vigorous era of knife innovation, and thus gained the reputation of treating knives as human teeth. Later, we entered a period of low ebb in tool innovation. Everyone was making so-called final products with the same structure according to the jointly designed drawings, and at the same time they were all making standard general-purpose tools that were the same over and over again. With the development of computer-aided design and CNC manufacturing technology, a strong material foundation has been provided for the innovation of tool structure, ushering in a new era of tool innovation.

At present, the momentum of tool structure innovation is very strong, and the new tool structures launched by various carbide tool companies have become the highlights of machine tool exhibitions in recent years. Innovative tool structures not only improve tool performance, but some even have a great impact on the development of tool varieties. For example, the structure of the milling cutter that can be sloped has greatly expanded the functions of the milling cutter and reduced the time of tool change. Its structural features have been extended to different types of milling tools, forming various milling cutters that can be sloped. , which promoted the development of milling processing technology and milling cutters. Other examples include large feed and small depth of cut milling cutters, unequal helix angle vibration-absorbing end mills, smooth turning inserts, thread turning tools and profiling turning tools with guide rails on the bottom of the blades, internal cooling structures of the tools, etc. enumerate. Each new tool attracts the attention of the industry as soon as it appears, and is quickly promoted in the industry, which plays a great role in developing the variety of tools and improving the performance of the tools. Many tool companies in our country only make tools but do not produce tool materials. They should pay more attention to the innovation of tool structures. Carbide blade

At present, there is still a lot of work to be done to speed up tool innovation in our country. In addition to updating and transforming equipment hardware, we must also pay attention to the following two aspects.

On the one hand, it is to improve the basic metal cutting knowledge of practitioners in the tool industry, including those in design, manufacturing, marketing, service and other aspects. In order to innovate grades and coatings, professionals engaged in materials and coatings must master the basic theory of metal cutting and become comprehensive talents. Pay attention to learning tool application technology, especially for development, marketing and field service personnel. If you don’t understand the requirements for using tools and don’t analyze and solve problems during use, it will be difficult to innovate tools. The innovation of cutting tools must be based on the mastery and application of basic knowledge, and we must strengthen learning in this area. Whether enterprises run their own study classes or participate in study classes organized by the society, they should be taken seriously and utilized.

On the other hand is the transformation of the tool industry. We must complete the transformation from a traditional tool manufacturer to a “manufacturing-oriented, user-oriented” manufacturing cutting processing technology service provider and processing efficiency supplier. “Manufacturing-oriented, user-oriented” is the core of the modern tool industry (enterprise). sign. To this end, it is necessary to be familiar with the technological characteristics, main workpiece materials, production models, development directions and product development of cutting processing in important industrial sectors of the manufacturing industry, so as to correctly and timely determine the development direction of one’s own products and become the driving force for innovation.

Many carbide tool companies in our country have implemented such transformation to varying degrees and have achieved certain results, but more efforts are needed. Serving users is a basic skill that modern tool manufacturers (enterprises) must possess. Only through service can we obtain first-hand information on tool innovation. As a tool element of productivity, cutting tools can continuously discover problems and innovate only in their application. In addition, users’ new demand information can also be obtained in advance.
