Recovery of cutting tool reuse with a variety of immediate and long-term benefits. Eliminate waste refers to reduce the consumption of resources, help enterprises to reduce costs. Recycling can increase the material supply. In addition, with the use of new raw materials (either by mining, or other means of production) manufacturing tool, process usually required less energy recovery and remanufacturing tool, and pollution to the environment is small. This further reduces the cost and reduces the influence of manufacturing process on the environment.
Before sufficient reason for reuse in the proposed tool recovery, first look at the raw material tool. Because the hardness and toughness of the perfect combination, made of hard alloy blades and other tools for hard 75%. of the global market for the first time in 20s of last century developed the tungsten carbide and cobalt tungsten is a kind of form. Mineral through chemical and heat treatment, the natural ore becomes available form. China segment tungsten production and consumption accounted for 79% of the world and 33%. in the world, 58% are used for the production of tungsten carbide. About 80% of the global production of cobalt from nickel or copper by-product. Application its range is more extensive, although only 12% of the world’s cobalt for the production of wear-resistant alloy (including hard alloy), but for the production of Cutting Tool Co in quantity is still large. Historically, the price of tungsten has maintained relatively Stable, but changes in the past 6 years, from 2004 to 2008, tungsten price doubled two times, rose to about $18 per pound price of tungsten.2008 in August for $13 per pound in December dropped to $11 per pound (Figure 1). The price fluctuation cycle longer cobalt, ranging from $7 A pound to $40 per pound in recent years.2008 August cobalt price is about $18 per pound.
