摘要： PROBLEM TO BE SOLVED: To manufacture a small-diameter and small-curvature lens and a lens forming metal mold surface with high accuracy and at a high grade by controlling a flow of slurry jetted from a pore provided in the tip of a polishing tool to a fixed flow and moving the polishing tool near by the surface of an object to be polished at a fixed stay time. SOLUTION: At the time of jetting slurry 4 obtained by previously mxing water 8 and fine abrasive grains 7 at a fixed ratio forcibly from a pore 3 to be strongly applied to the surface 5 to be polished, the fine abrasive grains 7 cause the polishing action to the surface of the surface 5 to be polished. An object 1 to be polished and a polishing tool are controlled to be relatively rotated or reciprocated so that the stay time of the polishing tool is controlled to make a pore 3 stay uniformly to the surface 5 to be polished. The liquid feed pressure and the flow of the slurry 4 are controlled so that the polishing tool is a little floated from the surface 5 to be polished to attain satisfactory polishing action of the fine abrasin grains 7. At this time, it is necessary to prevent such a movement locus control that a specified part of the pore 3 polihses a specified part of the surface 5 to be polished.
