Carbide rings are carbide cutting tools, which are suitable for different rough grinding parameters, cutting materials and non-metallic materials. Applied to traditional automatic and semi-automatic lathes, etc. Yihai Group focuses on the production of high-quality carbide rings, and specializes in supplying various high-quality carbide rings. So how is the hard ring produced? .

The first step is to use high-purity raw materials. High-purity tungsten powder is produced by reducing tungsten oxide in an all-hydrogen reduction furnace.

Then low pressure sintering is used. The low-pressure sintering pressure of the hard ring produced by Yihai can reach 100 kgf, and the internal pores of the alloy can be effectively eliminated, so as to obtain a high-hardness and high-strength blank with good densification. The temperature control system of xj*** can effectively Reduce quality fluctuations.

Then extrusion molding. Using automatic extrusion equipment imported from Germany, overpressure automatic pressure relief extrusion equipment can be adjusted according to different requirements, which is conducive to the production of different types of bars.

Finally, the bar is finely ground. Zhuzhou Wanfeng adopts CNC grinding machine, which has a polishing rate, which can quickly remove the damage layer generated during polishing, improve the surface finish, and achieve a mirror effect. Precision grinding bar: diameter tolerance D≤±0.01 length tolerance L≤±0.5.
