Technical Field

The invention relates to a machining cutting fluid filtering device.

Background

Machining refers to a process of changing the physical dimensions or properties of a workpiece by a mechanical device. The difference in the machining method can be divided into cutting machining and pressing machining.

A lathe is a machine tool for turning a rotating workpiece mainly with a lathe tool. The lathe can also be used for corresponding processing by using a drill bit, a reamer, a screw tap, a die, a knurling tool and the like. Lathes are used primarily for machining shafts, discs, sleeves and other workpieces having a surface of revolution, and are the most widely used type of machine tool in machine manufacturing and repair plants.

During the machining of the lathe, due to the high rotational speed of the workpiece, a large amount of heat energy is generated in contact with the tool, and the accumulation of such heat energy can cause deformation or sticking of the tool bit, for which purpose the temperature of the cutting fluid (also called coolant) is required to be reduced by spraying.

The cutting fluid is recycled, in the prior art, a backflow hole is formed in the bottom of a material groove for collecting chips, a negative pressure pipe is butted, and the cutting fluid is extracted by using negative pressure of a negative pressure pump for circulation. However, in this extraction method, the hole diameter of the return hole is relatively small, and the return hole is easily covered with chips, resulting in a poor return effect, and therefore, the cutting fluid often overflows the outside of the chute.

Therefore, the machining cutting fluid filtering device is designed, wherein the machining cutting fluid filtering device can be directly installed in a material groove, the structure of the material groove is not damaged, meanwhile, cutting fluid can enter in two directions, and the cutting fluid can circulate rapidly.
