Composite Particle Polishing Method |

|
At the present level of polishing technology the use of polishing pads is indispensable, but some problems do occur, such as deterioration in the accuracy of the shape of a work piece, e.g. drooping edges caused by elasticity of the polishing pad or instability of finishing caused by clogging. To solve these problems, we are developing a composite particle polishing method - a new method of mirror surface finishing without using polishing pads. As shown in the diagram, in this polishing method, microscopic polymer particles called carrier particles form a barrier between the work piece and the plate, and the polishing effect of abrasive grains adhered to or attracted by the carrier particles improve the polishing process.
By using a hard plate instead of a polishing pad, the improvement of the precision shaping of a work piece and long term stabilization as a finishing feature is made possible. |
