Claims (5)

In a spectacle lens periphery processing apparatus that includes a setting unit that sets processing conditions such as a processing mode and the like applied to the lens material and the periphery of the lens, and processes the lens periphery according to the set processing conditions.
Eyeglasses comprising: calculation means for calculating a machining end time required until the machining is completed based on the machining conditions set by the machining condition setting means; and display means for displaying the calculated machining end time. Lens peripheral processing device. 2. The spectacle lens peripheral edge processing apparatus according to claim 1, wherein the setting means includes at least one of chamfering, grooving, drilling and faceting as settable processing conditions, and the amount of chamfering is set in the setting of chamfering. Including means for setting, including means for setting the groove width and depth in the setting of the grooving process, including means for setting the hole diameter and hole depth in the setting of the hole processing, and in setting of the facet processing Includes means for setting the faceting area and its width,
The calculation means obtains the chamfering time based on the setting of the chamfering amount when chamfering is set, and obtains the grooving time based on the setting of the groove width and depth when grooving is set. When hole machining is set, the hole machining time is calculated based on the hole diameter, hole depth, and number of holes. When facet machining is set, facet machining is performed based on the machining width of the facet area and the number of facet areas. A spectacle lens peripheral edge processing apparatus characterized in that time is obtained, and the time required to complete the processing is calculated by adding the set time for each processing step. The eyeglass lens peripheral edge processing apparatus according to claim 1 or 2, wherein each processing step is completed for the time displayed by counting down the processing end time and displaying the remaining time as the processing progresses, and the time displayed by the countdown. And a correction means for correcting each time based on the time of the remaining processing steps. The spectacle lens peripheral edge processing apparatus according to any one of claims 1 to 3, wherein each processing step is performed with respect to a progress ratio display means for displaying the progress ratio in accordance with the progress of processing and the progress ratio displayed by the progress ratio display means. And a correction means for correcting each time based on the remaining processing time. 5. The eyeglass lens peripheral edge processing apparatus according to claim 1, wherein the lens material that can be set by the setting unit includes plastic and polycarbonate, and when the polycarbonate is set, the calculation unit is configured to apply plastic to the plastic. An eyeglass lens peripheral edge processing apparatus, wherein the processing end time is obtained by different calculations.
