step two, starting a first ball screw sliding table 4c and a second ball screw sliding table 4e to enable the working ends of the first ball screw sliding tables to drive a first servo motor 4a to move along the horizontal direction, and starting the first servo motor 4a to enable an output shaft of the first servo motor to drive a graver body 5 to coaxially rotate through a three-pin positioning assembly 4 b;
step three, starting a third ball screw sliding table 4f, enabling a working end of the third ball screw sliding table to drive the graver body 5 to descend along the vertical direction for engraving, and enabling the elastic rotating cover 6a to overcome the elastic elasticity of the second spring 6e and abut against the top end of the aluminum plate before the graver body 5 is abutted against the aluminum plate due to the fact that the bottom end of the material poking strip 6a3 is lower than the bottom end of the graver body 5;
step four, in the moving engraving process, because the bottom end of the elastic rotating cover 6a is uniformly distributed with a plurality of balls 6a1, the friction force between the elastic rotating cover 6a and the aluminum plate is reduced, and gaps exist between the bottom ends of the elastic rotating cover 6a and the fixed ring 6b and the aluminum plate, so that the elastic rotating cover 6a coaxially rotates relative to the engraving knife body 5, namely, the turbine blade 6a2 rotates along the circumferential direction of the elastic rotating cover 6a, the top of the turbine blade 6a2 generates negative pressure, so that gas is discharged outwards from the gap between the bottom of the turbine blade 6a2 and the bottom of the elastic rotating cover 6a, and waste chips generated in the engraving process are guided by the turbine blade 6a2 and are discharged outwards from the bottom of the elastic rotating cover 6 a;
step five, when the graver body 5 needs to be replaced, the bevel gear 4b7 is rotated, so that the positioning pin 4b4 is withdrawn from the positioning groove 5a1 along the radial direction, the clamping of the inserting column 5a is released and stopped, different graver bodies 5 are replaced, and the graver bodies 5 are coaxially and fixedly arranged in the three-pin positioning assembly 4b through the inserting column 5a, so that the graver bodies 5 are coaxial with the output shaft of the first servo motor 4 a.
