LENS PROCESSING DEVICE AND LENS PROCESSING METHOD

WIPO Patent Application WO/2015/045470

A1

Provided is a lens processing device and the like that are capable of performing, with good precision, a plurality of processing steps, including a centering process and a D-cut process, in a single device without increasing the complexity of the device or the complexity of and time required for the work. This lens processing device comprises: a workpiece spindle (110) that holds a workpiece (1) and that can rotate about a rotational axis (RW); a rotary motor (115) that rotates the workpiece spindle (110); a grinding tool (10) that forms a ring; a grindstone spindle (120) that coaxially holds the grinding tool (10) and that can rotate about a rotational axis (RG) perpendicular to the rotational axis (RW); and a rotary motor (122) that rotates the grindstone spindle (120). An outer peripheral face (1c) of the workpiece (1) is ground by at least the grinding tool (10) being rotated and a plane grinding face (12a), which is an end face of the grinding tool (10), abutting the outer peripheral face (1c).
