Eyeglass lens processing system

An eyeglass lens processing system for processing an eyeglass lens, the system comprising:

• a main processing apparatus comprising a first lens chuck that chucks the lens, a roughing tool, a first bevel-finishing tool, a lens edge measuring unit that obtains an edge position of the lens based on target lens shape data, and a first computing unit that calculates roughing data for controlling the roughing tool and calcualates first bevel-finishing data for controlling the first bevel-finishing tool;
• and
• a sub processing apparatus that is provided separately from the main processing apparatus and comprises a second lens chuck that chucks the lens, and a second bevel-finishing tool having a smaller diameter than the first bevel-finishing tool,
• wherein the main processing apparatus comprises:
• a setting unit that sets whether processing of the lens is performed by the first or second bevel-finishing tool;
• a transmission unit that, when processing by the second bevel-finishing tool is set, transmits to the sub processing apparatus at least one of second bevel-finishing data for controlling the second bevel-finishing tool or data for the sub-processing apparatus to calculate the second bevel-finishing;
• and
• a first control unit that, when processing by the first bevel-finishing tool is set, performs roughing based on the roughing data and bevel-finishing based on the first bevel-finishing data, and when the processing by the second bevel-finishing tool is set, performs only the roughing based on the roughing data, and
• wherein the sub processing unit comprises a second control unit that, when the processing by the second bevel-finishing tool is set, performs bevel-finishing based on the second bevel-finishing data.
