With the development of science and technology, the technical level of the production of polycrystalline diamond materials in China has improved to a great extent, and its products have formed a certain scale of production and application, polycrystalline diamond has become an ideal material for manufacturing cutting tools, drilling bits and other wear-resistant tools.

Its main applications are in the following aspects.

1、Polycrystalline diamond composite cutting tools

In metal cutting technology, improve the material of cutting tools to improve cutting efficiency, reduce cutting costs than any other process changes have more potential, so in order to continuously improve production efficiency, reduce costs, and enhance the competitiveness of products, the industrialized countries are vigorously carry out cutting tools.

The industrialized countries are vigorously carry out research and development of new materials for cutting tools. Under the impetus of this understanding, new foreign tool materials, high-efficiency tool new products and tool manufacturing new processes continue to emerge.

At present, the variety of superhard material tool is increasing, not only lathe, boring tool, reamer, milling cutter, molding tool, and for the manufacture of some of the gears of the tool, at the same time the production is also increasing.

With the rapid development of automobile manufacturing and woodworking market, CNC machine tools, machining centers and automatic production lines are becoming more and more popular, the production and application of PDC superhard cutting tools have also been rapid growth, and the use of various PDC inserts is increasing.

All kinds of PDC inserts are used more and more, and its tool durability can be increased dozens of times compared with carbide tools, and the cost of the tool when processing is much lower than that of cemented carbide.

2、Polycrystalline Diamond Composite Drill Bits

Using diamond composite piece to do the cutter wing of the drill bit can greatly improve the working efficiency of the drill bit, it is the ideal drill bit material for drilling into medium-hard and hard rock formations, PDC drill bit has the characteristics of high efficiency, simplicity and durability compared with other drill bits.

PDC drill bit is characterized by high efficiency, simplicity and durability compared with other drill bits, and it has long service life, under the same conditions, the service life is 10-30 times that of cemented carbide drill bit, and it can significantly reduce the number of lifting times and improve the efficacy in the drilling process, and it is also suitable for a wide range of rocks, and it plays an important role in improving the level of China's petroleum drilling technology.

3、Polycrystalline diamond wire drawing die

Polycrystalline diamond wire drawing die is a kind of mold widely used in wire drawing industry, compared with other molds, it has high hardness and wear-resisting degree, it can control the accuracy of the wire very well, and the finish is good, the production efficiency is high, the cost is low, it is a kind of cost-effective mold.

Is a cost-effective mold, has been successfully used to draw copper, aluminum, nickel and other non-ferrous metals, stainless steel and a variety of alloy wire.

4、Wear-resistant devices

Physical and mechanical properties of polycrystalline diamond research shows that the friction coefficient of diamond composite piece of steel and natural diamond is similar, so the polycrystalline diamond composite piece is widely used in the manufacture of parts with higher requirements for wear resistance, to replace cemented carbide and natural diamond.

For example, they are used in V-groove surfaces that require high wear resistance, molds or fixture parts that require high wear resistance or low roughness, etc. They are very effective.
