Most of manufacturers use traditional machining or electrical discharge machining to process tungsten carbide. In the final stage, it often requires polishing procedure to fulfill quality demands.
The current polishing method is mainly traditional mechanical polishing, with cutters, rollers, and sand paper to remove raised part. The more precise the quality we required, the more time and cost we need to burden. So far, many manufacturers have still taken both reducing manual polishing process and gaining the same quality surface standard into consideration.
This case is about mirror processing of tungsten steel. Assisted with Ultrasonic high-frequency and vibration, the finished artifacts can skip the polishing process and reach the quality standard to mirror level (RA <0.002).
