In the machining process of the numerically controlled lathe, a cooling system is required for cooling because a large amount of heat is generated when the tool and the workpiece are cut. The cooling systems of the prior art are mounted on lathes and then spray cooling fluid towards the approximate location of the cutting head using spray pipes. However, in the process of machining a workpiece by using a numerically controlled lathe, the shape, the size and the position of the cutting edge of the adopted tool are different, so that the cutting positions of the tool and the workpiece are different, but the position of the coolant spray cannot be changed at any time along with the change of the tool, so that the tool cannot be sufficiently cooled in the machining process of some tools, and the phenomena of fast tool abrasion, poor cutting precision and the like are caused. In order to solve the above-mentioned drawbacks, a large flow rate of coolant is generally used to increase the cooling range of the coolant sprayed on the tool, but this results in large consumption of coolant, splashing of coolant around, relatively dirty machining area, and the like, which is not favorable for environmental protection and results in high cost of treating the used coolant.
