Abstract

PURPOSE: To obtain precise and quick center-drilling by operating a handle to shift a drill head supported to be slided on rails crossing at right angles to the right and left, forward and backward, and upward and downward for a highly precise positioning. CONSTITUTION: A work 12 is placed at a fixed position on a table 11, and given center-drilling at a point P by a center drill of a drill head 16. The drill head 16 is supported by a sliding body 14, and shifted upward and downward by the operation of a handle 18. The sliding body 14 is slided on rails PX 1 and RX 2 supported by sliding bodies 13 1 and 13 2 to be slided on rails RY 1 and RY 2 . The center drill of the drill head 16 is moved to the point P by the operation of the handle 18. Each sliding work can be locked by pushing down the handle 18 for giving center drilling at the point P easily and precisely. COPYRIGHT: (C)1980,JPO&Japio
