Superhard cutting tool carbide cutting tools belonging to energy efficiency, with the development of China's high-end manufacturing, has been widely used, from a certain level, the promotion of high-end manufacturing carbide cutting tools to achieve rapid development. First, as the mother of the machine tool manufacturing industry grew by leaps and bounds CNC machine tools carbide tools help expand the market. A machine to go with a dozen or even more tools, tool is a consumable requires regular replacement. 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 be maintained average annual growth rate of 9.3 in the next five years is expected to increase consumption of nearly 4 billion yuan PCB drill. Finally, the address exploration drilling of mining in the amount of carbide drills completed by 60-80, with mines continue to lower grade and mining depth continues to increase, carbide cutting tools for mining depletion over the next five years is expected to maintain 30 the average annual growth rate.
