| titleOfInvention | Polishing method of special-shaped workpiece |
| abstract | The invention relates to a polishing method of a special-shaped workpiece, and belongs to the field of polishing. A polishing method of a special-shaped workpiece is characterized in that the workpiece to be processed is immersed into silicon oil-based polishing solution, the workpiece is controlled to rotate at the rotating speed of 300-800 r/min, meanwhile, a magnetic field with the strength of 0.5-5T is applied to the silicon oil-based polishing solution, and polishing is carried out, wherein the polishing solution comprises magnetorheological fluid and an abrasive, and the magnetorheological fluid comprises the following components in percentage by mass: 20-75% of silicone oil, 3-8% of thixotropic agent, 0-2% of antioxidant, 0-3% of lubricant and 40-70% of carbonyl iron powder, wherein the proportion of the abrasive to the magnetorheological fluid is as follows: the mass ratio of the grinding material to the carbonyl iron powder is 1-2: 10. The invention provides a silicone oil-based polishing agent and a polishing method by using the same. |
