In response to this problem, the teacher proposed the rationalization proposal as shown in the accompanying drawings.

Remove the spindle on the drill spindle gear box 1, install a piece of triangular iron 2 with screws and nuts on the underside of the box, and a small motor 3 on the triangular iron. A small bowl-shaped wheel mounted on the motor 4, the wheel to be mounted side high, making it in the cutting
