The competition of the precision parts industry is the competition of materials, the product characteristics and functions made of different materials are very different, for the improvement of materials every precision parts processing enterprise has not stopped, taking the CNC industry as an example, the early CNC parts are made of aluminum materials, because of its low cost, capacity forming, has been recognized by the market, but with the change of market needs, the development of the manufacturing industry, tungsten steel and other high-density materials are also applied to the parts processing industry. Parts made of tungsten steel have unique advantages, which we will explain in the following introduction:

　　 The advantages of tungsten steel parts processing are as follows:

　　1. Low MC coefficient, which provides it with a wide range of use in conflict parts;

　　2. Tungsten steel punching needle production and processing high strength, which can withstand the load for a long time;

　　3. Compared with metal, MC nylon has low hardness and does not damage the wearing parts;

　　4. Outstanding resilience, can twist without deformation, and can persist and resist repeated impact;

　　5. Simplify the repair and maintenance of the machine, save labor, excellent mechanical cutting and processing function, and advance labor productivity;

　　6. Noise absorption and shock absorption, MC nylon modulus is much smaller than metal, and the attenuation of sensation is large, providing a useful path better than metal to prevent noise.

　　7. Wear resistance and self-smoothness, which provides better operating functions than bronze cast iron carbon steel and phenolic laminate in oil-free (or deoiled) smooth use, reducing consumption and saving energy; --Tungsten steel punching needle

　　8. High chemical stability, resistance to alkali, alcohol, ether, hydrocarbons, weak acid, smooth oil, detergent, water (seawater), and has the characteristics of odorless, non-toxic, odorless and rustless, which provides excellent conditions for its widespread use in alkali corrosion resistance, environmental protection and cleaning, food, textile printing and dyeing, etc.

　　The transformation and upgrading of the manufacturing industry must bring about the revolution of materials, and manufacturing enterprises must also constantly adapt to the development and progress of products. In the processing and manufacturing industry of various countries, the research and development and production of materials is the main competitiveness, who masters the high-end material technology who can lead the industry, in the field of aerospace electronics, but also new materials have become a strong guarantee for technology, in the civil industry, the advanced performance of materials ensures the quality and life of products, and even the position in the market, the application of different materials in the precision parts processing industry will bring different product quality to enterprises, in this case, enterprises are constantly innovating for the research and development and production of new materials. Precision tungsten steel parts are such a new material production product, which has been applied to many precision machinery and equipment lines and played an important role.
