10. A method for supplying cutting fluid to a fixed-point spraying type Swiss-type lathe, using the cutting fluid supply device of any one of claims 1 to 9, characterized in that: The supply method comprises the following steps: Step 1: When in use, the waste cutting fluid is subjected to chip separation and oil-water separation, and the treated cutting fluid is then added into the filter cartridge (607) through the liquid inlet (10); Step 2: Start the driving motor (601) to drive the connecting plate (603) on the rotating rod (602), and drive the filter cartridge (607) to rotate through the fixing frame (604) on the connecting plate (603), so that the cutting fluid in the filter cartridge (607) is thrown out through the filter mesh on the surface of the filter cartridge (607), and the metal iron chips are adsorbed on the inner wall of the filter cartridge (607) and the surface of the steel chip adsorption plate (610), thereby performing preliminary filtration on the cutting fluid; Step 3: After the cutting fluid is initially filtered, the cutting fluid is discharged into the connecting sleeve (801) through the liquid outlet (611) and the liquid outlet (7), and then the cutting fluid is finely filtered through the filter plate (805) so that the filtered cutting fluid can be used normally; Step 4: drain the filtered cutting fluid into the fluid storage tank (9), and adjust the temperature of the cutting fluid by the temperature controller (11), maintaining the cutting fluid at 20±2°C for conventional processing or 18±1°C for alloy processing, so as to be suitable for different situations; Step 5: Connect the output pipe (13) to the nozzle, and then extract the cutting fluid in the liquid storage tank (9) through the liquid extraction pump (12), and spray it out from the nozzle through the output pipe (13). At the same time, different spray modes are adopted according to different workpieces to achieve high-pressure and precise fixed-point spraying.
