China has become the world's largest consumer of machine tool, from the point of cutting tool production, production of carbide cutting tools in recent years, sustained growth, and high speed steel cutter began showed a trend of decline, causing domestic cemented carbide indexable tool market share is lower than the import tool.
According to the cutting tool association statistics show that China has become the world's largest machine tool consumer, followed by Japan, the United States, Italy, etc. From the point of cutting tool production, production of carbide cutting tools in recent years continue to grow, showed a trend of decline the start of HSS cutting tools, carbide into exports were significantly increased, the main export object to Asia, followed by Europe, then in North America and other regions.
High speed machining is generally considered to increase production, reduce the manufacturing cost of processing technology. Dry processing or the concept of minimal quantities of lubricant is now processing industry to reduce the environmental protection and the main goal of the production cost. For cutting tool manufacturer and coating suppliers, the most important thing is productivity. Cutting performance, cutting speed, cutting quantity per unit time) increased by 20%, the manufacturing cost will be reduced by 15%. More and more strict processing requirements need further development, cutting tool material and coating to improve processing conditions and improve the tool design.
From the point of current usage, domestic cemented carbide indexable tool market share is lower than the imported cutting tools, investigate its reason, mainly has the following three points:
1. The product quality consciousness is not strong domestic producers lack the quality consciousness of some of the knives. China-made indexable insert material quality is poor, less varieties, the specification is not complete, the increase in the quality of the product is difficult to tools. Look from the appearance quality of the product, the import tool appearance, color and texture is superior to domestic tool. On product performance, compared with domestic knives, imported cutter machining high dimensional accuracy, good stability, high durability, high removal rate, tool and its accessories have good interchangeability, after the general assembly can meet precision requirement.
2. Incomplete pre-market after-sales service abroad many tool company has included for the user to choose knife, knife, timely replacement of supply,, as good service, and many domestic tool vendors do very not enough in this aspect, the service is simple and extensive.
3. The mode of production of small workshops still accounts for a large proportion because of the economic and other reasons, some domestic tool factory still accounts for a large percentage of small workshops production mode, the processing personnel technical level is low, simple equipment, difficult to guarantee the quality of the product. Caused by tool cutting tool parts processing and assembly quality products of some quality common fault is still difficult to eliminate.
Expert analyzes believed that the cutting tool material has entered the era of development represented by carbide, compared with the high speed steel, cemented carbide has better performance and higher cutting efficiency, it with superhard materials, is the important guarantee to realize modern cutting technology and efficient processing. No good cutting tool material, cutting tool innovation and the progress of cutting process are lack of the necessary material base. Fundamentally solve the problem, will involve the adjustment of industry structure, speed up with hard alloy materials and cutting tool production base for research and development ability of construction process, increase rapidly carbide cutting tools in the proportion of all tools.
2014 China international exhibition on carbide AD hoc high-performance technology exhibition - by sandvik, kenner metal, tyco, walter, IMC, mitsubishi, zhuzhou diamond, xiamen and other components of the gesac measures are useful "high-performance cutting tools technology exhibition" will become the most eye-catching. This exhibition will make enterprises experience carbide high-tech area for its "green, environmental protection, low carbon, energy saving" of carbide project vivid interpretation of the charm of science and technology.
