Embodiment Construction

[0026] Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic configuration diagram of a processing unit of a spectacle lens peripheral processing device according to the present invention.

[0027] On the base (base) 170, the carriage part 100 including the carriage 101 and its moving mechanism is mounted. The lens LE to be processed is held (clamped) by lens chucks 102L and 102R rotatably held on a frame 101 to rotate, and is rotated by a grinding wheel as a processing tool mounted on a grinding wheel shaft (grindstone spindle) 161 . 162 for grinding, and the grinding wheel shaft 161 is rotated by the grinding wheel rotation motor 160 fixed on the base 170 . The grinding wheel 162 of the present embodiment includes: a coarse grinding wheel 162a, a sharp edge fine grinding and a flat edge fine grinding grinding wheel 162b, a sharp edge polishing (bevel-polishing) and a flat edge polishing (flat-polishing) grinding w...

Abstract

The invention provides an eyeglass lens processing apparatus for processing eyeglass lens circumference which has characteristics in that the apparatus includes: a drilling tool processing a hole through a lens front side; an inclining unit inclining the drilling tool axle with random angle relative to a clampingpiece axle; an inputting unit for selecting an input screen in which hole position data referring to a lens front surface is input or an input screen in which hole position data referring to a lens rear surface is input; a setting unit setting an angle of the hole including a selecting unit that selects forming hole angle along lens surface normal direction; and an operation controlling unit, when the hole position base surface is input as processing start surface of the hole processing apparatus, lens surface of processing start surface side is determined through lens position measuring unit according with output hole position data, and hole processing data is obtained, when base surface of inputting hole position is not lens surface of processing start surface side, hole processing data is obtained according with measured lens surface hole position and pre-set hole angle.

Description

technical field [0001] The present invention relates to a spectacle lens processing device for processing a hole for mounting a rimless frame on a spectacle lens. Background technique [0002] The following eyeglass lens processing device is known (for example, refer to US-2006-0178086-A1 (Japanese Patent Application Laid-Open No. 2006-189659 ), hereinafter referred to as Patent Document 1): it is held on the eyeglass lens and processed to be used for installation. A hole machining tool such as an end mill for the hole of a rimless frame of a point frame is relatively moved to the front of the spectacle lens held on the clip to perform hole machining. In this device, hole position data for hole machining is input. At this time, since the hole machining is performed with the tip of the hole machining tool directed toward the front surface of the lens, the hole position data is input based on the target lens shape viewed from the front surface of the lens. [0003] Therefore...
