ABSTRACT:
A computer controlled positioning table for use in automatically rotating a large diameter article into which an evenly spaced circle of bolt holes are to be drilled. The article to be drilled is centered and clamped onto a table top of the table and then the computer rotates the table top incrementally to precisely position the article relative to an associated stationary drill stand that is used to drill the desired holes in the article. Rotation of the table top is computer controlled, allowing the operator to select the number of bolt holes for each article. Once the table top has rotated to the proper position, locking mechanisms and support roller provided under the table top hold the table top stationary in the proper position while a hole is drilled in the article.
