Dngn integrally sintered PCBN tool

Dngn series integrally sintered PCBN blades, also known as integrally polycrystalline CBN blades, are 55 ° rhombus in shape.

Generally, polycrystalline cubic boron nitride is used as raw material and is synthesized by six sided hydraulic press under high pressure and high temperature.

After synthesis, they have high wear resistance, impact resistance and chemical stability.

※ application field: Dngn series CBN blades are in the shape of 55 ° rhombus. Generally, polycrystalline cubic boron nitride is used. There are three better grades: bts2800, bts7600 and bts7800. They are synthesized by six sided top hydraulic press under high pressure and high temperature. After synthesis, they have high wear resistance, impact resistance and chemical stability. CBN blades are mainly used for cutting hardened steel, cold cast iron and surface thermal spraying materials. The excellent cutting performance of CBN blades can not be well reflected in the processing of materials with medium hardness. When processing workpieces above hrc45, the tools show extremely excellent superhard performance. Its service life is 10 times longer than that of cemented carbide tools.

※ The main processing materials of Zhengzhou Bote CBN lathe blades are: various cast iron, quenched steel, nodular iron, chilled cast iron, high chromium cast iron, high manganese steel, high-temperature hard alloy, powder metallurgy, alloy steel, tool steel, mold steel and other difficult to process metal materials. The workpiece processing fields include: quenched bearing steel, roller, brake disc, slurry pump, quenched gear, ball screw, high-temperature alloy Rockwell hardness between hrc45-70. CBN blade belongs to super hard precision turning blade. The blade has high wear resistance, good surface effect of precision turning, and the surface finish can reach Ra0.8. The use of turning instead of grinding greatly improves the production efficiency and reduces the production cost. It is widely used in medical equipment, automobile parts and aerospace processing fields.

※ Can also be customized according to customer requirements

Introduction to rcgx series CBN blades:

Rcgx series cubic boron nitride inserts are positioned with a 120 ° taper, so that the inserts and the cutter body are tightly fixed together to complete the cutting of difficult to machine materials and workpieces. The service life is 5-10 times higher than that of cemented carbide tools and ceramic tools.

Rcgx series cubic boron nitride tool application:

This type of blade is highly applied to the finishing of the raceway of the rotary table bearing, realizing the turning instead of grinding, and the efficiency is increased by more than 5 times compared with grinding. Cubic boron nitride cutter has extremely high hardness and red hardness, and can withstand high cutting speed. It is suitable for ultra-high speed machining of steel workpieces. It is an ideal cutting tool for high-speed machining of quenched steel, chilled cast iron, high-temperature alloy and other materials. Because CBN tool can obtain good surface roughness when machining high hardness parts, cutting hardened steel with CBN tool can greatly improve the machining efficiency on the premise of ensuring the quality, and has the longest service life in high-speed cutting. Cubic boron nitride tool is suitable for turning and milling of high-strength steel, mainly for semi finishing and finishing. Using CBN tool to finish machining, the cutting effect is significantly better than that of cemented carbide and ceramic tools.

Dimple blade - integrally sintered CBN blade

The dimple series CBN blade adopts a special production process, adding a "groove" design on the CBN integrated sintered blade, and innovating the dimple form, which can replace the original welded CBN blade without replacing the cutter bar.

※ Integrated sintering, to prevent CBN cutter particles from falling off;

※ Groove positioning, more secure clamping, no need to replace the original cutter bar;

※Good chip breaking and chip cutting control, long service life;

※ Meet the needs of large cutting depth and high-speed cutting, and the maximum cutting depth can reach 1 / 3 of the cutting edge;

※ Own CBN fine powder factory, with more advantages in cost control;

Tcgw integrated composite PCBN blade

Tcgw series integral composite PCBN blade is an equilateral triangle shaped, single-sided composite polycrystalline CBN tool.

The upper side of the blade is made of cubic boron nitride and is positioned with a central hole.

It has the advantages of high bonding strength, rough and fine machining, and good impact strength.
