[0032] Working principle: When cutting, first select a suitable fixture, then place the workpiece inside the mounting bracket 316, and then rotate the limit bolt 318 to push the fixture and clamp the workpiece. Subsequently, the first cylinder 302 is lifted through the control platform 2. The first cylinder 302 lifts the mounting plate 303. After lifting to a suitable position, it pauses. Then the second cylinder 307 is opened through the control platform 2. The second cylinder 307 pushes the slider 308 to translate. After translating to a suitable position, it pauses. Then the third cylinder 312 is opened through the control platform 2. The third cylinder 312 pushes the sliding plate 313 to translate. After translating to a suitable position, it pauses. Then the motor 403 is turned on through the control platform 2 and cutting is performed. During the cutting process, the lamp ring 405 is turned on through the control platform 2 to illuminate the workpiece. After cutting is completed, the limit bolt 318 is removed and the workpiece is taken out. Then the suction port is stretched through the telescopic tube 504 to near the mounting bracket 316, and then the suction fan 506 is turned on to absorb the debris on the mounting bracket 316. After long-term absorption, the connecting plate 503 is opened, the filter screen 502 is pulled out, the internal debris is poured out, and then reinstalled. Thus, the use process of a numerically controlled milling machine for high-precision machining is completed.
