Common Application Fields and Development Prospects of PCD Tools

PCD cutter is a kind of glass cutting cutter with excellent performance. The cutter wheel made of polycrystalline diamond is mainly used for high-precision and high-quality cutting of liquid crystal glass in the electronics industry. It can also cut architectural and automotive glass. It is an ordinary glass cutter and Ideal replacement for carbide glass cutter wheels.


Ⅰ. Common application fields of PCD cutting tools


1. 3C industry


As consumers have more and more requirements for lightness, thinness, shortness, smallness and fashion, new technologies based on high-tech digitalization, intelligence and networking - "3C" products (Computer, Communication, Consumer Electronic products (ConsumerElectronics) emerge in an endless stream, and the number and variety of products are extremely rich. In the shell application of "3C" products, magnesium aluminum alloy has gradually replaced ABS, PC and other materials. At present, with the development of 5G communication technology, new material ceramics (zirconia) are more and more applied to mobile phone back shells and other fields .


2. Automotive industry


Aluminum alloy has become an ideal material for reducing weight required by the transportation industry. There are many kinds of aluminum alloys on the market. The Si content of automobile pistons, wheel hubs, engine skirts, pin holes and cylinder blocks exceeds 10%. Therefore, the hardness and service life of the tools are very high, and metal matrix composites (MMC) and carbon fiber composites have also been applied to the automotive field. The use of polycrystalline diamond cutters can ensure the processing speed and processing quality.


3. Aerospace industry


The most common composite material used in aerospace is CFRP (carbon fiber W strong plastic). Carbon fiber composite materials currently account for about 50% of airframe materials. PCD cutting tools are particularly effective for it. Typical CFRP parts are aircraft wing spars, as well as bearings, pump parts and sleeves made from this part material.


Ⅱ. The development prospects of PCD cutting tools


The automobile manufacturing industry promotes the rapid development of PCD cutting tools: In recent years, in order to reduce the total weight and fuel costs of automobiles, aluminum alloy materials have been used more and more in auto parts, and polycrystalline diamond (PCD) tools have a long life and can achieve High-efficiency, high-speed, high-precision machining, for which the use of polycrystalline diamond (PCD) tools for processing aluminum alloy auto parts is also growing rapidly.


China's PCD tool market continues to expand with the development of tool technology. Currently, there are more than 100 polycrystalline diamond(PCD) turning tools use points. The application of PCD cutting tools has further promoted the research on its design and manufacturing technology. Many well-known universities and cutting tool manufacturers in China are actively carrying out research, development and production in this area.


In a word, PCD tool is a newly developed application field in recent years, and the market prospect is very promising, which greatly broadens the market of polycrystalline diamond. At the same time, polycrystalline diamond has achieved good results in occasions requiring high wear resistance, high dimensional accuracy and maintaining good contact.
