A grinding water tank apparatus capable of recycling grinding water used for machining an eyeglass lens, comprising:
- a tank in which the grinding water is stored;
- a first filter disposed upper a surface of the grinding water in the tank;
- and
- a suction unit which draws bubbles developing in the tank through the first filter.
A grinding water tank apparatus capable of recycling grinding water used for machining an eyeglass lens, comprising:
- a tank in which the grinding water is stored;
- a cover removable from an upper portion of the tank;
- and
- a pump which draws the grinding water in the tank, which is mounted at a lower portion of the cover through a mount member and disposed under the grinding water in the tank by mounting the cover to the tank.
A eyeglass lens machining apparatus for machining an eyeglass lens, comprising:
- a machining chamber in which a machining tool is provided;
- a tank in which grinding water is stored;
- a first filter disposed upper a surface of the grinding water in the tank;
- a suction unit which draws bubbles developing in the tank through the first filter.
A eyeglass lens machining apparatus for machining an eyeglass lens, comprising:
- a machining chamber in which a machining tool is provided;
- a tank in which grinding water is stored;
- a cover removable from an upper portion of the tank;
- and
- a water supplying unit which supplies the grinding water in the tank to the machining chamber, wherein the water supplying unit includes a pump which draws the grinding water in the tank, which is mounted at a lower portion of the cover through a mount member and disposed under the grinding water in the tank by mounting the cover to the tank.
