Tungsten carbide polishing

Tungsten carbide polishing is crucial for parts that require a high degree of smoothness. CNC processing can achieve a smoothness suitable for low smoothness demands. For parts that require a higher degree of smoothness, WEDM processing can achieve the required size and surface roughness, or direct processing with mirror EDM finish to RA0.2 can be used. For high-precision smoothness, hand polishing or fluid polishing is recommended. (Please refer to the tungsten carbide polishing finish grade comparison table at the bottom of this article for more information.)

Manual Tungsten carbide polishing operation

When manually polishing tungsten carbide, we use various tools such as ultrasonic polishing machines, resin grinding wheels, and diamond grinding paste. We select different mesh sizes of polishing sandpaper based on the finish requirements. For finishes of Ra0.05, Ra0.02, and Ra0.01, diamond abrasive paste is necessary to achieve the desired level of smoothness.

In some cases, particularly for products with tiny holes or cemented carbide parts that require batch polishing, we use a fluid polishing process. We work with stable suppliers who specialize in fluid polishing to meet the specific requirements of these parts. This ensures that we can consistently deliver high-quality products that meet our customers’ needs.
