The abrasive can be silicon carbide powder.
1. Fluid polishing relies on high-speed flowing liquid and the abrasive particles it carries to wash away the surface of the workpiece to achieve the purpose of polishing.
2. Commonly used methods include: abrasive emery jet processing, liquid jet processing, fluid power grinding, etc. Fluid power grinding is driven by hydraulic pressure, which causes the liquid medium carrying abrasive particles to reciprocate across the workpiece surface at high speed.
