Bolt Circle

By

Boltcircle A bolt circle pattern is the diagram that indicates a series of holes drilled in a polar fashion around a point that are equally spaced both by degrees and by the radius indicating the centers of each drilled hole.  This is used quite frequently by industry as a means of fastening housings over shafts, gear boxes, etc.  For a CNC machinist or programmer to be able to program the milling machine to drill this series of holes, that machinist will have to have the X and Y center locations for each hole.  This location point is essential because the machines that drill these holes base the location upon the center of the drill.   Contributed by: Debbie Barnhouse.
