Abstract

Two pairs of processing units 10a, 10b which are supported by a support frame 13 formed on a machine frame and independently acting with each other are provided at the centering and edging machine having one work rest 7 and a loader 9 on the machine frame. The two pairs of processing units 10a, 10b sharing the machine frame, the work rest 7, and the loader 9 are provided on one machine, which realizes the centering and edging machine on which two lenses are simultaneously processed in a roughly equal installation area to the conventional centering and edging machine having only one processing unit.

Description

technical field

[0001] The present invention relates to a lens centering machine for processing the outer periphery of a lens based on the optical axis, and to a device for grinding the outer periphery of a lens clamped by cup-shaped fixtures at the opposite ends of a set of workpiece axes that are installed on the same axis and rotate synchronously . Background technique

[0002] Lens aligning machine with general structure, such as Figure 11 As shown, the spherical surface of the lens 5 is held by cup-shaped lens holders 3 and 4, and the holders 3 and 4 of the cup-shaped lens are installed on the opposite ends of the moving-side workpiece shaft 1a and the fixed-side workpiece shaft 1b arranged on the same axis, synchronously The workpiece shafts 1a, 1b are rotated, and the grinding stone 6 adjacent to the workpiece shafts is servo-controlled in the parallel direction (Z direction) and the direction (X direction) of the workpiece shafts to process the outer periphery of th...
