High hardness cemented carbide rods subvert the traditional tungsten cobalt alloy material

Have to say,cemented carbide rods for light weight and high hardnesssubvert the traditional tungsten cobalt alloy material, reached the foreign advanced level and fill the gap. At the same time, than imported products in the market price low nearly doubled, greatly reduce the production cost and improve the competitive ability of products.

The rapid development of foundry machinery industry, requirements of cutting speed, feed volume, high precision, long service life, however, the traditional hard alloy cutting tools have been unable to meet the above requirements. In foreign countries, super cemented carbide rodshave as deep processing instruments. At present, Chinese cemented carbide industry structure is not reasonable, more in the low-end products and high-end product development is slow, heavily dependent on the United States, Europe,Japan imports, especially in the fields of research, related work is still in the stage of system modeling and simulation,which has not yet formed independent intellectual property products and mass production.

5 years ago, a research group in the study of a new generation of cold bit alloy bar products for a long time, the high speed dry cutting of stainless steel and other materials in the process of cutting red hardness and toughness of the poor, after testing hundreds of times, by adjusting the formula and sintering of powder and other measures, independent research and development of a titanium the base matrix, light weight and high strength alloy bars, the proportion of 7.2g/cm3, greatly improving the cutting tool materials such as stainless steel stem at high light in the process of the service cycle.

In order to overcome the defects of poor toughness of cemented carbide, by adding other elements, obviously improves the mechanical properties and physical properties of hard alloy, light alloy microstructure, fracture toughness and flexural strength improved, wear resistance, high temperature resistance, impact resistance, resistance to surface diffusion and antioxidant capacity were improved in different degree.

The above describes the difference between foreigncemented carbide rodsand China’s. I believe that we should word hard alloy rodare not unfamiliar, so we all know what are the use of hard alloy bar? For everybody here for detailsbelow:

1. It applies to micro drilling

2.Ithas good abrasion resistance and bending strength, mainly used for the production of extruded bars, suitable for general drill tool wear parts.

3.Ithas good abrasion resistance and bending strength, mainly used in the production of extruded bars, making small diameter micro drill tool, the use of clocks and other processing, whole reamer tools and wear parts.

4.Cemented carbide rodsfor a fine granular tungsten steel, tungsten steel bar has the high hardness, good bending strength, wear resistance and not easy to collapse, not easy to fracture. The micro drill is a special material, widely used in tungsten steel milling cutter, knife and wear parts.
