Description

A Fluid Supply Pipe Assembly}

The present invention relates to a fluid supply pipe assembly, and more specifically, to a fluid supply pipe assembly capable of producing large quantities of microbubbles to maximize the function of the fluid in the cutting oil flowing inside the pipe.

Conventionally, when processing a workpiece made of metal, etc. into a desired shape using a machine tool such as a grinding machine, drilling machine, or machining center, processing fluid (e.g., cooling fluid) is supplied to the contact area between the workpiece and the cutting edge of the tool. The heat generated during processing is cooled or the cut debris (also called chips) of the workpiece is removed from the processing point. Cutting heat generated due to high pressure and frictional resistance at the contact area between the workpiece and the tool cutting edge wears the tool cutting edge or reduces its strength, resulting in cutting edge breakage and reduced tool life. Additionally, if the cut debris from the workpiece is not sufficiently removed, it may stick to the tip of the blade during processing, reducing processing precision.

Machining fluid, also called cutting fluid, reduces the frictional resistance between the tool and the workpiece, removes cutting heat, and also has a cleaning effect by removing chips from the surface of the workpiece. For this purpose, it is desirable for the coolant to have a low coefficient of friction, a high boiling point, and the characteristics of penetrating well into the contact area between the tool cutting edge and the workpiece.

However, the prior art had the following problems.

The internal structure of the fluid pipe for generating microbubbles was complex and assembly was cumbersome, causing inconvenience in operation and use.
