摘要： The work-piece processing machine of the present invention is compact and has two tools for precisely processing a work-piece. In the work-piece processing machine, the work-piece is processed by a first tool (22) and a second tool (24). Diameter of the second tool (24) is shorter than that of the first tool (22). A first motor (28) rotates the first tool (22). A second motor (36) rotates the second tool (24). The first motor (28) and the second motor (36) are attached to a rotatable member (30). Rotating means (34) rotates the rotatable member (30) in a vertical plane.
