tungsten carbide die has high hardness, high wear resistance, heat resistance and corrosion resistance and other excellent properties, so it has a wide range of applications. In use, good polishing can improve the light refractive index of the workpiece surface, which is brighter from the human visual point of view, but the size of the parts does not change, and the roughness of the surface does not change.Polishing is an important process in the processing of cemented carbide dies, in which the difficulty coefficient of tungsten steel cemented carbide dies is higher, but the polished dies are not only practical and beautiful, but also can increase the wear resistance.So what are the polishing processes?First, magnetic grinding and polishingMagnetic abrasive polishing is the use of magnetic abrasive under the action of the magnetic field to form an abrasive brush, the mold grinding processing.Two, chemical polishingChemical polishing is to make the cemented carbide die in the chemical medium surface microscopic convex part of the concave part preferred to dissolve, so as to get a smooth surface.This method can polish the cemented carbide die with complex shape, and can polish many workpieces at the same time with high efficiency.Three, electrolytic polishingThe principle of electropolishing is the same as that of chemical polishing, which selectively dissolves tiny protrusions on the surface of the material to make the surface smooth.Compared with chemical polishing, the effect of cathodic reaction can be eliminated and the effect is better.Four, ultrasonic polishingPut into the abrasive suspension and placed together in the ultrasonic field, relying on the oscillating effect of the ultrasonic wave, the abrasive in the mold surfa
