The adjustment of the domestic hard alloy cutting tool industry is in no hurry

Judging from the development of the domestic market, the market share of domestic carbide indexing tools is lower than that of imported tools, so it is extremely urgent to adjust the structure of the industry.

According to research by Luo Baihui, secretary-general of the International Die & Metals and Plastic Industry Suppliers Association, China has become the world's largest machine tool consumer, followed by Japan, the United States, and Italy. Judging from the output value of the tool, the output of cemented carbide tools has continued to increase in recent years, while high-speed steel 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 areas.

Judging from the current situation of use, the market share of China-made carbide indexable cutting tools is lower than that of imported tools. The main reasons are as follows:

First, 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. .

Second, the pre-sale after-sales 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 regard, and their services are simple and extensive. .

Third, the small workshops still account for a large proportion of production methods. Due to economic reasons, the production methods of small workshops in some domestic tool manufacturing plants still account for a large proportion. The processing technology of processing personnel is low, and the equipment is simple, 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.

High-speed machining is generally 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%, manufacturing cost will be reduced by 15%. More stringent machining requirements require further development of tool materials and coatings, improved machining conditions and improved tool design are now developing. From the perspective of the situation, the development of cutting tool materials into cemented carbide represents an era of development. Compared with high-speed steel, carbide has better performance and higher cutting efficiency. Together with superhard materials, it is an important guarantee for efficient machining of modern cutting technology. If the company wants to develop rapidly, it should adjust its industrial structure and accelerate the process of its production base.
