Abstract (en)
A lens chamfering machine for chamfering a corner defined by a lens plane and a peripheral ground plane of a lens to be ground comprises a chamfering grindstone for chamfering the corner, a drive mechanism for driving at least one of the lens and the chamfering grindstone to change a relative positional relationship therebetween, and a control unit for determining a relative positional relationship required to attain a desired chamfer shape based on data on the shape of the lens, causing the periphery of the lens to be ground and controlling the drive mechanism based on the determination. <IMAGE>
