The Characteristics Of Cemented Carbide Tools

wallpapers Resource 2020-12-02
Cemented carbide is an alloy material made of hard compounds of refractory metals and bonding metals through powder metallurgy.
Efficient cutting is an advanced processing technology that quickly moved towards practical application in the 1990s. It has been widely used in aerospace, precision molds, auto parts, and precision machinery industries.
Statistics show that in the field of metal cutting, (1) the price of cutting tools is reduced by 30%, and the unit cost of the final product is reduced by 1%; (2) the tool life is increased by 50%, and the unit cost is reduced by 1%; (3) the cutting efficiency is improved 20%, the unit cost can be reduced by 20%. It can be seen that high-efficiency cutting can reduce labor costs, energy consumption, equipment depreciation and other expenditures during the product life cycle by improving processing efficiency, thereby greatly reducing product costs. Not only that, efficient production efficiency can help companies seize market opportunities, thereby enhancing their comprehensive competitiveness.

Cemented carbide tools have balanced physical properties, making them an ideal tool material. In fact, cemented carbide has been playing an important role in improving cutting speed and cutting efficiency in the past 90 years. With the further development of tool coating technology, the cutting performance of cemented carbide has undergone essential changes, and the scope of application in high-efficiency cutting is continuously expanding. As a tool material, cemented carbide is currently the most important part of high-speed cutting technology and plays an indispensable role in cutting practice.
Hard cutting tools can be roughly divided into drills, reamers, taps and end mills. Drills, reamers and taps are hole processing tools. End mills are mainly used for milling planes and curved surfaces. The output value of hard reamer and hard tap is not big. Drills and end mills are the main products of hard tools, accounting for more than 98% of hard tools.
Domestic hardened tools are often concentrated in low-grade drills and milling cutters and micro-diameter tools in the PCB industry. Although this type of tool has a considerable market, its added value is very low, and it has gradually become a resource-consuming product. The high-end hard tool market is dominated by European, American and Japanese products.
