Tank unit for grinding water used in processing eyeglass lens, and eyeglass lens processing apparatus having the same

摘要

A grinding water tank unit which allows grinding water used in processing an eyeglass lens to be reused, has: a water tank for storing the grinding water; and a partition plate for partitioning an interior of the water tank into a drain chamber and a water suction chamber. The partition plate defines a vertical opening adjacent an interior side surface of the water tank and extending in a depthwise direction of the water tank and a horizontal opening adjacent an interior bottom surface of the water tank and extending in a direction substantially perpendicular to the depthwise direction of the water tank so that a channel is secured between the drain chamber and the water suction chamber by the openings.
