We claim the ornamental design for the boring machine, as shown and described.
The application file contains at least one drawing executed in color. Copies of this eventual patent or patent application publication with color drawing(s) will be provided by the Office upon request and payment of the necessary fee.
FIG. 1 is a front perspective view of the boring machine embodying our design;
FIG. 2 is a rear perspective view of FIG. 1;
FIG. 3 is a front elevational view of FIG. 1;
FIG. 4 is a rear elevational view of FIG. 1;
FIG. 5 is left side elevational view of FIG. 1;
FIG. 6 is a right side elevational view of FIG. 1; and,

The broken lines in the drawings illustrate portions of the boring machine that forms no part of the claimed design.
The drawings are submitted in color which is necessary because color is an integral part of the claimed design.
