CBN tool and PCD tool widely used to show a good trend

Casting process, as the name suggests, in terms of popular is the high temperature melting of molten metal poured into the mold, the cooling and solidification after the desired shape and performance of the parts of the production process. Casting history in China has existed for thousands of years, from the Bronze Age to the industrial revolution, the machinery industry are inseparable from casting, casting process represents a national machinery industry level, machinery industry to aircraft, high-speed train parts, , Construction machinery, electrical equipment and other equipment manufacturing industry, small pots and pans are used casting process, for example, we see the countryside to cast aluminum pot, aluminum basin and so on.
Casting the workpiece from the material can be divided into two categories: one is ferrous metal castings such as gray cast iron, ductile iron, alloy cast iron, and steel castings and so on. One is non-ferrous metal castings such as cast copper alloy, cast aluminum alloy; with the development of the machinery industry, a variety of casting alloy performance has been greatly improved, and casting parts of the machining more and more high-speed cutting and dry The most rapid development of cutting, high speed cutting and dry cutting tools is cubic boron nitride tool (CBN tool) and diamond tool (PCD tool). As an industrial "tooth", CBN and PCD tools provide the basis for casting difficult materials and batch high speed cutting.
CBN tool and PCD tool development status
At present, foreign advanced countries have been large-scale investment in the use of CBN tools and PCD tool, which with foreign high-speed CNC machine tools in the past 20 years is inseparable from the rapid development, especially in the automotive industry, foreign CBN tools and PCD tool has accounted for To more than 30% of the tool market share. CBN tool and PCD tool with its high hardness, high wear resistance, good thermal conductivity and low coefficient of friction and other excellent performance, especially for the automotive industry such as CNC automatic processing lines on the application.
Compared with foreign countries, the current domestic CBN tool and PCD tool is not well developed, it is due to the domestic tool manufacturing equipment and manufacturing technology, but the customs, restricting the use and promotion of these tools; foreign CBN tool and PCD tool Because of its expensive price reasons, so many users discouraged; enterprise technical staff habits and awareness of the new technology is not enough, the CBN tool and PCD tool tool performance, processing and use of technology did not fully understand and master.
However, from the successful experience of foreign countries, with CBN tools and PCD tools in the field of machining high-speed, high precision, to car grinding, green manufacturing and other advantages, will be like high-speed CNC machine tools in China's development process, Is the trend, unstoppable.
Application Advantages of CBN Tool and PCD Tool in Automobile Industry
In recent years, with the continuous development of China's automobile industry, the automotive industry has become an important pillar of the national economy, CBN tool and PCD tool with high-speed CNC machine tools to use, can shorten the non-state-of-the- Processing time to more than half, but also reduce the non-processing time, increase machine life, improve processing efficiency.
At present, foreign CBN tool and PCD tool in the cylinder block, cylinder head, axle, gearbox, bearing cover and other parts processing applications. CBN tool for the shaft, gear and wear ring, the use of turning very convenient to the car on behalf of the mill, but also a very good place to do abroad.
CBN tool and PCD tool development trend
It is expected that during the 12th Five-Year Plan period, China's tool market share will reach almost 360 million, according to the current super-hard material market share accounted for more than 10% count, within five years, CBN tool and PCD tool market share will reach nearly 40 Million, which for all superhard materials tool enterprises are a huge cake to be developed.
CBN tool and PCD tool on behalf of the tool material development direction, is an ideal cutting tool material, this material is not renewable, and gradually lack of carbide cutting tool is an inevitable trend. I believe that through the domestic enterprises and scientific research institutions of unremitting efforts, China's superhard materials tool business will have a better tomorrow, CBN tools and PCD tools will be in the cutting processing will go further and stronger.
