ABSTRACT:
A centering device for locating and aligning the center of a workpiece with the center axis of the spindle of a manufacturing machine such as a drill press and the like, comprising a centering pointer and a centering block; the centering pointer having a needle slidably disposed therein and an indicator lamp and being adapted to be detachably mounted to the spindle of the manufacturing machine, the centering block having a cylindrical surface and an L-shaped cut away to be mounted onto an edge of the workpiece, the L-shaped cut away having one surface passing through the center axis of the centering block. The needle has a lower point adapted to be coasted along a convex path of the cylindrical surface of the centering block, and an upper end adapted to come into contact with a probe member, which is frictionally held within the centering pointer so as to act as an electrical contact for causing the indicator lamp to light, when the needle comes to a peak point of the convex path indicating that the center axis of the spindle is aligned with the center axis of the centering block.
