Claims

[Scope of utility model registration request]

A grinding wheel 2, which has oblique grinding surfaces 2a, 2a for chamfer grinding, formed on both sides of the circumferential surface, which is a grinding surface, is installed so that it can rotate and move forward and backward based on the power of a motor. A lens centering machine equipped with a left and right slide base frame C rotatably equipped with first and second lens support shafts 6 and 7 which are abutted against each other and provide clamping support for the lens L at their abutting surfaces. At the same time, a stopper disk 10 is fixed to the second lens support shaft 7, and a microscrew 11 is positioned so as to be able to abut against the stopper disk 10 at a predetermined distance, and furthermore, the microscrew 11 can be rotated in forward and reverse directions by motor power. The slide cylinder 14 is threadedly fitted to the rotating screw shaft 13, and the annular part 15a of the moving operation piece 15 whose base end is fixed to the left and right slide base frames C mentioned above is attached to the slide cylinder 14. The slide cylinder 14 and the annular part 15a are fitted with a loose fit, and the slide cylinder 14 and the annular part 15a are provided with appropriate rotation stopping means. A lens centering machine characterized in that they are interlockably connected with a spring 19 interposed therebetween.
