  • Work-piece processing machine
    Patent number: 6682407
    Abstract: 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 and a second tool. Diameter of the second tool is shorter than that of the first tool. A first motor rotates the first tool. A second motor rotates the second tool. The first motor and the second motor are attached to a rotatable member. A rotating unit rotates the rotatable member in a vertical plane.
    Type: Grant

  • Finishing machine for cast products
    Patent number: 5044124
    Abstract: The present invention provides a finishing machine for casted products, which can uniformly remove fins on circumferential side faces, upper face, etc. of casted products by correcting amount of abrasion of a rotary grindstone. Therefore, the finishing machine for casted products has means for detecting the amount of abrasion of the rotary grindstone and means for correcting which adds the amount of abrasion of the rotary grindstone to the amount of travel of the rotary grindstone and a work.
