Carbide Tool as a high-performance super-hard tool, with the development of some high-end manufacturing in China, has been more widely used, it can be said high-end manufacturing has greatly promoted the development of carbide cutting tools . First, as the mother of the machine tool manufacturing industry, especially the growth of CNC machine tools will help to expand by leaps and bounds carbide cutting tools market. We know that a machine should be equipped with a dozen or more kinds of tools, and the tool is a consumable item, you need to be replaced regularly to ensure efficient production efficiency. Secondly, the construction of railways and urban rail shield machine brought carbide demand is also growing rapidly. Supplies in the shield machine tool belongs, the shield tunneling machine per 200 meters -300 meters must be replaced once the hob bit. By 2015, the National Underground Railroad traffic mileage is expected to reach 3,900 km by 2020, this figure is expected to reach 7,000 kilometers. Once again, the pillar industry of information to be included on the basis of PCB industry sub-sectors will maintain an average annual growth rate of 9.3 percent in the next five years, consumption is expected to increase nearly 4 billion yuan PCB drill. Finally, the address of the exploration, underground mining in 60% -80% of the amount by carbide drill drilling is completed, continue to lower grade as mining and mining depth continues to increase, mining carbide cutting tools in the next five years is expected to consume maintain a 30% average annual growth.
