[0025] Refer to Figure 1 , a second fixed seat 12 is fixedly connected to the outer wall of the cross beam 4, and a second servo motor 13 is fixedly connected to the outer wall of the second fixed seat 12; a second lead screw 14 is fixedly connected to the output end of the second servo motor 13, and a second nut 15 is threadedly connected to the outer wall of the second lead screw 14; the outer wall of the second nut 15 is fixedly connected to the outer wall of the saddle 5;

[0026] Specifically, the cross beam 4 can fix the second fixed seat 12, the second fixed seat 12 can fix the second servo motor 13, and by starting the second servo motor 13, the second lead screw 14 can be rotated, and then the saddle 5 can be driven by the second nut 15 to slide on the outer wall of the cross beam 4 to realize the horizontal movement adjustment of the tool rest 11.

[0027] Refer to Figure 1 and Figure 3 , a sleeve workpiece 16 is arranged on the upper surface of the chuck 3; a circular hole 17 is formed in the outer wall of the column 2; a chip collection groove 18 is formed in the upper surface of the base 1, and an adjustable support wheel 19 is arranged on the lower surface of the base 1; a sealing plate 20 is fixedly connected to the outer wall of the column 2;
