Being capable of performing drilling, boring. Reaming, spot facing and tapping on vertical, horizontal and angular surfaces of work-piece at different directions in space, the need for changing work set-ups is reduced to a minimum. And as a moveable unit, it is well suited for assembly shops, workshops, and repair shops. It can be readily moved to the work, saving valuable man-hours, when large and heavy components are being dealt with in the process of assembly or machining.

The machine is provided with screw jacks and self-aligning rollers at the base so that it can be readily leveled and easily moved from place to place. These rollers and screw jacks can be detached so that the machine may be installed on a proper foundation and used as a stationary unit.

The machine is mainly composed of a heavy base with T-Slots, a rigid column, a radial arm, a speed change gearbox and a drilling head.

Anti-friction bearings are used throughout, including the spindle shafts in the speed change gearbox and elevating screw on the column.

The drilling head can be moved along the radial arm guide ways by a hand wheel though rack and pinion and swiveled on its saddle. It is provided with a dial graduated in 360 ½ at1 ½ intervals. Play in the arm guide ways can be eliminated by adjusting a gib fitted on the upper guide way.

Speed changes, provided by the speed change hear box, are controlled by a single lever. The spindle is brought back to the original position by spring.

The arm can be raised or lowered along the column through an elevating screw by manipulating a lever. And it can be swiveled in both the horizontal plane about the centerline and the vertical plane.
