Tool material enters carbide age

Judging from the output value of the tool, the output of cemented carbide cutting tools has continued to increase in recent years, while high-speed steel cutting tools have begun to show a downward trend, and the import and export volume of cemented carbide has increased significantly. The main export target is Asia, followed by Europe, and then North America and other regions.

High-speed machining has been widely considered as a processing technology that increases production and reduces manufacturing costs. The concept of dry processing or trace lubrication is the main goal of the processing industry today to reduce environmental protection and production costs. For tool manufacturers and coating suppliers, the most important is productivity. Cutting performance (cutting speed, cutting amount per unit time) is increased by 20% and manufacturing costs are reduced by 15%. Increasingly stringent machining requirements require the further development of tool materials and coatings, improved machining conditions and improved tool design.

Judging from the current situation of use, the market share of domestically-made carbide indexable cutting tools is lower than that of imported cutting tools. The main reasons for this are as follows: 1. The awareness of product quality is not strong. Some domestic tool producers lack sufficient quality. awareness. The quality of domestically-made indexable inserts is poor, the variety is small, and the specifications are incomplete, which makes it difficult to improve the quality of cutting tools. From the aspect of product appearance quality, the appearance, color and texture of imported tools are obviously better than domestic tools. In terms of product performance, compared with domestic tools, imported tools have high dimensional accuracy, good stability, high durability, high resection rate, and good interchangeability of tools and accessories. After assembly, they can meet the accuracy requirements. . 2. The pre-sale service is not perfect. Many foreign tool companies have included thoughtful services such as user selection, supply, adjustment, and timely replacement. Many domestic tool manufacturers have done very inadequately in this area, and their services are simple and extensive. 3. Small workshops still account for a large proportion of production methods Due to economic and other reasons, the production methods of small workshops of some domestic tool manufacturing plants still account for a large proportion, and the processing personnel have low technical standards and simple equipment, and it is difficult to ensure product quality. It is still difficult to eliminate some of the quality problems of cutting tool products caused by the machining quality and assembly quality of tool parts.

Experts believe that the tool material has entered the development era represented by cemented carbide. Compared with high-speed steel, carbide has better performance and higher cutting efficiency. Together with superhard materials, it is modern The important guarantee for efficient machining of cutting technology. Without good tool materials, any tool innovations and advances in cutting processes lack the necessary material basis. Fundamentally solving this problem will involve adjusting the industrial structure, speeding up the construction of a production base with hard alloy materials and tool development capability, and rapidly increasing the proportion of cemented carbide tools in all cutting tools.
