The nano-diamond composite coating not only has the characteristics of strong adhesion and wear resistance of the conventional diamond coating, but also has the advantages of smooth and smooth surface of the nano-diamond, small friction coefficient and easy grinding and polishing, and the nano-diamond composite coating drawing die is Carbide is a substrate, a conventional and nano-diamond composite coating is applied to the inner hole surface, and a new product obtained by grinding and polishing the coating is obtained. The nano-diamond composite coating drawing die developed by this project has been applied in more than 70 production enterprises such as Jiangsu Shangshang Cable Group Co., Ltd. and Shanghai Huapu Cable Co., Ltd., which has brought significant economic benefits to the application enterprises. The output value increased by 1.4 billion, the profit was 45.1 million yuan, the tax revenue was 60.09 million yuan, and the savings were 35.71 million yuan.
The subject uses chemical vapor deposition (CVD) to coat the surface of the hard alloy drawing die and other wear-resistant devices with a nano-diamond composite coating. The mature process for preparing the nano-diamond coating is obtained, and the nano-coating is completed. Layer structure and performance testing work, using nano-diamond composite coating technology to research and develop a variety of coating drawing molds and wear-resistant device products, solving key technical problems such as coating adhesion, uniform coating and coating surface finish. It has been widely used in drawing molds and wear-resistant devices for electric power, communication, building materials, mechanical processing and other industries, and has broad market application prospects.
Flap Disc
Flap disc, commonly known as flat emery cloth wheels, emery discs, flower impellers or elastic grinding discs, are a large variety of coated abrasive conversion products, which press the cut coated abrasive sheets one by one. It is formed by sticking adhesive to the back cover plate along the circumference. The flap disc are called strong elastic grinding discs. They are made of calcined emery cloth, which uses mesh, nylon, plastic, steel paper and other materials as the base. Attached abrasive tools, evenly distributed in a fan shape to ensure the best grinding effect. The particle size is 36#-320#, 60# and 80# are the most common, and the outer diameter is 4"-7" installed on the angle grinder. Angle grinders are mainly installed on hand-held Power Tools to polish and polish welds, burrs, chamfers, surface rust removal, and surface polishing of various metal and non-metal parts.
The flat emery cloth wheel (flap wheel) is formed by sticking multiple emery cloth sheets on the tray in a fan-shaped superimposed arrangement, and the bonding angle between each emery cloth and the tray plane is 10°-30°. The emery cloth arrangement of the utility model can make When the abrasive cloth wheel grinds and polishes the workpiece to be processed, the cutting angle is optimized to ensure that the base material of the abrasive cloth wheel and the grinding are consumed simultaneously, which obviously improves the overall wear resistance and grinding efficiency of the flat abrasive cloth wheel, and prolongs the service life of the abrasive cloth wheel. Grind the surface of metallic and non-metallic materials.
product advantages:
Compared with the resin grinding wheel for fixed abrasives, it has the advantages of polishing and polishing at one time, shortening the operation time, saving the grinding cost, high efficiency, good heat dissipation, high grinding efficiency, reducing operator fatigue, increasing machine life, etc. It has strong elasticity, High tensile and bending strength and good grinding effect. The grinding speed is fast, the effect is good, and the noise during grinding is low. It is suitable for various industries or fields of manufacturing such as major metal parts factories and machinery factories. Good weather resistance, salt spray resistance and heat resistance, suitable for use in different regions.
Scope of application:
It is suitable for polishing of stainless steel, metal, metallurgy, automobile, wood, marble and other industries. It is especially suitable for the processing of stainless steel and can replace the resin-shaped grinding wheel. It has strong elasticity, high tensile and bending strength, good self-sharpening, high grinding rate, and low noise. It is suitable for welding seams in the box. Polishing of the edges.
There are different classifications of louvers according to different angles. The following are two common classifications:
According to the appearance: T27 VS T29
Flap disc generally have two shapes, curved and flat.
The flap disc type is also called the T27 type, and the curved type generally refers to the T29 type.
The flap disc type (T27) has a flat surface. It is mainly used to polish the flat surface and the external edges and corners. The flap disc and the workpiece are angled during work, which can complete the grinding and polishing at one time, reducing the work flow.
The curved surface of the curved louver (T29) has an upward arc, which makes the T29 flap disc have a better cutting ability on the plane. When working, the T29 type grinding wheel forms an angle of 15° to 25° with the grinding surface, which is mainly used to deal with the grinding of contours and edges. When there are higher requirements for speed and cutting ability, T29 flap disc is undoubtedly the best choice.

According to the type of abrasive particles: ceramic alumina VS zirconium corundum VS alumina
According to the type of abrasive selected, the flap disc can be divided into three types: ceramic alumina, zirconium corundum and alumina.
Because ceramic alumina itself has many crystals, it has good self-sharpening, relatively neat edges, good heat dissipation, and long service life. Therefore, ceramic alumina louvers are mainly used for the grinding of stainless steel, aluminum and other hard metals.
Zirconium corundum itself is a polycrystalline crystal, with fast cutting speed, good self-sharpening, and strong resistance to high pressure and high temperature. Therefore, zirconium corundum louver blades have strong cutting ability and long service life.
Alumina: single crystal, the cutting ability begins to decline at the beginning of grinding, and the abrasive grains are not easy to break, so the alumina flap disc is suitable for the processing of common metals.
