関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a polishing tool capable of easily controlling a dish surface and capable of processing a workpiece having an arbitrary shape.

皿工具が使用されている。2. Description of the Related Art The manufacturing process of an optical element such as a lens or a mirror usually includes a rough grinding process using a grinder such as a curve generator, a sanding process (lapping and smoothing), a polishing process and the like. In the sanding step and the polishing step, a dish tool shaped according to the curvature of the workpiece is used.

の製造コストの増大と製造効率の低下につながる。However, in the above conventional dish tool, the shape of the dish surface gradually deteriorates as the machining progresses. Since the quality of the finished surface depends on the quality of the dish shape, the operator needs to correct the dish shape of the dish tool promptly if a change is recognized during the machining. In addition, the operator adjusts the processing conditions (processing conditions such as the swing width of the countersunk tool, insertion and removal of the pin before and after, the number of rotations of the tool shaft, etc.) so that the countersunk shape of the countersink tool is not changed as much as possible during the processing. You also need to do it. While these operations are essential for stably producing high-quality products, they require a great deal of labor and time, leading to an increase in product production costs and a decrease in production efficiency.

大し、製品の製造コストの増大につながる。[0005] Further, the above-mentioned conventional countersunk tool is accurately shaped in accordance with the shape of the workpiece, that is, the curvature of the specific shape. In other words, the use of one countersunk tool is limited to only processing a product of a specific shape. Therefore, in small-quantity production of a wide variety of products, dish tools must be prepared for each lot, which leads to an increase in the production cost of the dish tool and an increase in the production cost of the product.

に修正することもできる。According to the polishing tool of the present invention, it is possible to adjust the amount of protrusion of the annular tool from the groove opening of each groove of the base jig without using another countersunk tool. Since the shape of the sliding surface (hereinafter referred to as the dish shape) can be changed, it can be used for processing workpieces of various shapes, and it can easily reduce the shape of the sliding surface that has deteriorated due to processing. It can be modified.
