[0037] In summary, when the precision machining cutter head self-protection milling machine equipment is used, the workpiece is placed on the surface of the mounting table 30, and then the milling head 48 is driven to move by the lifting mechanism 40 to mill the workpiece. In the process of milling the workpiece, the output end of the first servo motor 4 drives the first screw 5 to rotate, so that the first moving block 6 drives the second guide rail 15, the mounting table 30 and the workpiece to move.

The metal debris is discharged into the collecting chamber 12 through the second top groove 28, the output end of the third servo motor 16 drives the second screw 17 to rotate, so that the second moving block 18 drives the mounting table 30 to move, and the output end of the fourth servo motor 29 drives the second winding roller 20 to rotate, so that a piece of the second sealing tape 22 is released from the outside of the second winding roller 20, and another piece of the second sealing tape 22 is wound around the outside of the second winding roller 20, and the liquid sprayed by the liquid supply mechanism 31 and the metal debris generated by milling the workpiece are introduced into the second side box 19 through the second moving groove 21, and the liquid and metal debris on the surface of the second sealing tape 22 are scraped off by the second scraper 24, so that the liquid and metal debris in the second side box 19 enter the discharge pipe 25, and then are discharged into the first top groove 27 through the discharge pipe 25, and then enter the collecting chamber 12;

[0038] The liquid and metal debris fall onto the surface of the filter belt 50, and the liquid passes through the filter holes on the filter belt 50 and falls to the bottom of the inner cavity of the base 1, and then is discharged through the drain pipe 55, while the metal debris remains on the surface of the filter belt 50. The output end of the fifth servo motor 56 drives a roller 49 to rotate, and this roller 49 drives another roller 49 to rotate through the filter belt 50, so that the filter belt 50 drives the metal debris on the surface to move to one side of the fourth scraper 52, and the debris is introduced into the discharge slot 51 through the fourth scraper 52, and then the debris enters the first fixed box 38 through the discharge slot 51, and then falls into the second receiving drawer 37. When the filter belt 50 moves to the nozzle 5 4, the external gas supply device sprays gas into the filter holes on the filter belt 50 through the nozzle 54, and the blockages in the filter holes on the filter belt 50 are sprayed into the second fixed box 53 through the discharge chute 57, and the gas is discharged to the outside of the first fixed box 38 through the exhaust pipe 35, and the debris falls onto the surface of the conveyor belt 59, and the output end of the sixth servo motor 60 drives one conveyor roller 34 to rotate, so that this conveyor roller 34 drives another conveyor roller 34 to rotate through the conveyor belt 59, so that the conveyor belt 59 drives the debris to move to one side of the discharge chute 32, so that the debris is scraped into the discharge chute 32 through the third scraper 33, and the debris falls into the first receiving bin 36.
