Product Description
K20 Cemented Tungsten Carbide Bar In Wear-Resistant Parts And Drills
Tungsten carbide bar can be divided into tungsten steel bars for PCB tools, solid tungsten steel bars, single straight hole tungsten steel bars, double straight hole tungsten steel bars, double spiral hole tungsten steel bars, three spiral hole tungsten steel bars and other types of tungsten carbide bar; According to the molding process, it can be divided into extrusion molding and molding molding. The difference is that the extruded bar has beautiful appearance and is easy to grind; The advantage of molded bar is that the density is relatively uniform, but it is not conducive to grinding.
Brief Introduction of tungsten carbide bar
In the sintering process of cemented carbide, due to powder sintering, compared with ordinary die steel, the performance has no directionality. In the processing process, different shapes can be divided according to the specifications, and the fracture toughness of superhard materials is small. In a large range, cemented carbide has both good hardness and toughness, so it has become the most widely applicable hard material and is widely used in engineering and tool products.

Characteristics of tungsten carbide bar
1. Low pressure sintering technology is adopted, and the quality is stable and reliable: the maximum sintering pressure can reach 100 KGF, and the internal pores of the alloy can be effectively eliminated, so as to
obtain high hardness and high strength blanks with good densification. The advanced temperature control system can effectively reduce the quality fluctuation.
2. Adopt overpressure automatic pressure relief extrusion equipment, and various types of bars can be produced: adopt automatic extrusion equipment imported from Germany, which can adjust the pressure
according to different requirements, which is conducive to the production of different types of bars.
3. High precision finish grinding of bar can achieve mirror effect: the CNC grinder is adopted, which has the maximum polishing rate, can quickly remove the damaged layer during polishing, improve the surface finish,
and can achieve the mirror effect at the highest. Precision of finish grinding bar: diameter tolerance D ≤± 0.03, length tolerance L ≤± 0.5.
