PURPOSE:To permit the groove and the vertical surface works for a large-sized work by installing a grindstone which can be fixed in turn at an arbitrary position and revolution-driven, onto a body which can be installed onto the main shaft of a milling machine for versatile use. CONSTITUTION:A body 1 is equipped with a tapered chank 1a which can be fitted onto the main shaft of a milling machine for versatile use. An arm 3 driven through a worm 5 is revolved by a clamp screw 7. An air motor 8 and a grindstone 19 are rotatably supported onto the arm 3. With such constitution, the groove and the vertical surface works for a large-sized work can be executed simply in the utilization of the three dimensional feed operation of the milling machine for versatile use. |
