technical field

The invention relates to a machine tool water tank, in particular to a multi-layer filtered machine tool water tank.

Background technique

During machine tool processing, the water tank of the machine tool needs to be used to filter the cooling water. If the filter effect of the water tank of the machine tool is not good, the filter iron filings are not clean enough, which will easily cause the working efficiency of the pump, and the machine tool parts are easy to wear out, shortening the life of the machine tool. .

The structure of the filter cavity inside the water tank of an ordinary machine tool is single, and it is only separated by a simple partition, and the partition is fixed by a spot welding process, and the material with a thickness of 2.0mm is used, which may easily cause insufficient welding strength, rigidity and sealing. The performance is not good, and the final result is water leakage, or even blockage of the oil well pump, resulting in abnormal supply of coolant.

Due to the poor filtration efficiency of the water tank of the machine tool, the temperature of the machine tool may be too high, which may easily damage the tool and the spindle; as iron filings enter the circulating cooling water, it may also affect the smoothness of the product.
