Abstract

An eyeglass lens processing apparatus (1) and a method for processing a periphery of an eyeglass lens (LE), wherein a material for the lens (LE) can be selected and thereupon a control unit (50) performs a first step and/or a second process step. During the first step, a lens rotating unit (101,102L,102R,120) rotates a lens (LE) in a plurality of defined positions and an axis-to-axis distance changing unit (101,140,150,155,156,157) changes the distance between the lens (LE) and the processing tool (168). Thereby a roughing tool (RT) cuts into the lens (LE) based on a calculated roughing path (RT). The lens (LE) is not rotated by the lens rotating unit (101,102L,102R,120) when the roughing tool (162) is cutting into the lens (LE). In the second step, the control unit (50) controls the lens rotating unit (101,102L,102R,120) and the axis-to-axis distance changing unit (101,140,150,155,156,157) to rough the lens (LE) based on the calculated roughing path (RT) while the lens rotating unit (101,102L,102R,120) rotates the lens (LE).
