Grinding is one of the oldest processing methods of mankind. With the development of industry, especially the processing of hard metal, it is an indispensable processing method. In the 1980s, the development of CN machine tools and machine tool machining centers in the developed western countries was developing at a high speed. The application of high-speed spindles and hard tools, the machining of the grinding machine seemed to be expensive. However, with the development of grinding technology, the grinding tools have been further improved. Abrasives are fundamentally improved in productivity by innovating the quality of the abrasives available, improving the structure and using a new binder system. The ultra-hard material CBN was invented as an abrasive for the manufacture of dicing sheets, which not only efficiently processed hard steel (HRc 45-65), but also doubled the durability of the dicing sheet. In particular, the CBN cutting piece of ceramic bond developed in the mid-eighties of the last century, represented by Krebs & Riedel of Germany (Meteor "Redder"), especially the technical breakthrough in the correction of sharpening It can be said that it is a revolution in grinding molds. The successful development of ceramic binder CBN aluminum abrasive cutting disc, in turn, puts technical parameters on the manufacturers of grinding machines to produce grinding machines that adapt to the nature of CBN cutting sheets. The CNC multi-axis grinding machine jointly developed by the film manufacturer has greatly improved the processing efficiency and reduced the production cost, and made this ancient processing technology have a new brilliance.
2 Classification of CBN cutting discs
The fiber cutting disc Chinese supplier made of CBN abrasive can be divided into the following four according to different processing techniques and the bonding agent of different components used. Their nature and use (referred to as machining applications) are also different.
1(1) Electroplated CBN/diamond cutting piece
The production process of the cutting piece is simple and the production cost is low. The molding is simple but there is only one layer of plating, which cannot be corrected. It is difficult to know when the grinding layer is damaged during the processing. Suitable for small batch machining and geometry complex forming grinding and as a correction roller.
2(2) Sintered CBN/diamond cutting piece
High hardness and high density, it is processed into a high-precision correction roller, which is costly. It is mainly used for the processing of correction rollers for cutting sheets and large quantities of superhard materials.
3(3) Resin CBN/Diamond Cutting Sheet
The production process of the cutting piece is simple and the production cost is low. Forming is simple but it is not easy to correct the shape. Used in the processing of multi-type small batches. Such as tool grinding and tool processing, and glass processing.
4(4) CBN/diamond cutting piece of ceramic bond
The processing technology and the formulation of the bonding agent are mastered by a few foreign manufacturers, such as Krebs & Riedel of Germany, which has just entered the Chinese market, WINTER of the world's largest abrasive mold group Saint-Gobain, TYROLIT of Austria, Wendt of Germany and WINTERTHUR of Switzerland. . The CBN/diamond cutting piece of the domestic ceramic bond has also made a breakthrough recently. The ceramic bond CBN/diamond cutting sheet has the advantages of strong grinding force, high-speed machining without burning the workpiece, and can be corrected and durable. It is the most ideal high-speed, high-efficiency and high-precision grinding tool. Use the following examples of work as an example to discuss the application of the cutting piece with colleagues.
3 application examples

It can be seen that for consumable products, it is necessary to use cost performance and not just look at the price. As a large-volume, stable quality production, the non-negligible parameters - time: the efficiency and the reduction of the scrap rate, the economic benefits. This shows that the cost of grinding production is low.
4 Conclusion
In the developed industrial countries, for high-volume, high-precision grinding, the hardness of the workpiece is HRc greater than 45, which is basically ground with ceramic CBN cutting sheets. It is widely used in major parts of automobiles such as camshafts, crankshafts, gearboxes and gears of gearboxes, bearings and brake pads. Grinding of precision machined parts such as guide rails, lead screws and motor shafts used in machine tools. The grinding machine parts are ground to an accuracy of 0, 3-0, 5 microns. CBN ceramic cutting discs are used for the grinding of rolled steel rolls and their applications in the fields of aviation, aerospace and military, etc.
Due to the long production cycle of CBN ceramic cutting sheets, users must have a planned order. A good manufacturer prepares the cutting piece according to the user's production process and the technical parameters of the workpiece. The choice of abrasive, the size of the abrasive particles, the tightness of the tissue, the hardness and shape of the low price disc for metal. The parameters of the production of the cutting piece should not only be based on the technical parameters of the workpiece but also the technical parameters of the grinding machine, so the CBN process is applied to both the buyer and the seller. It is a technology with high technical content. It must be purchased through professional channels to purchase suitable cutting sheets to improve production efficiency and reduce production costs.
