PROBLEM TO BE SOLVED: To provide a spectacle lens machining device which allows an operator to set a hole position of a back frame without requiring skills of the operator, and carries out hole machining. SOLUTION: The machining device has a drilling tool for mounting a rim-less frame on a lens, and carries out machining by moving the machining tool to the front surface or the rear surface of the lens. The machining device is composed of: a data input means inclusive of a selecting means for selecting whether hole location data is input with reference to the lens front surface or the lens rear surface; a setting means for setting the angle of the hole; a measuring means for measuring the hole location in a lens chuck shaft direction by abutting a measuring element on each of the lens front surface and the lens rear surface, based on the hole location data; and a control means for measuring the front surface hole location when input of the hole location data with reference to the front surface is selected, and carrying out drilling via the measured front surface hole location, based on the set hole angle, while measuring the rear surface hole location when input of the hole location data with reference to the rear surface is selected, and carrying out the drilling via the measured rear surface hole location, based on the set hole angle.
