ABSTRACT:
A precision power saw assembly which includes a saw table manufactured for exceeding close tolerance cutting of metals by a circular saw blade. The saw blade and its arbor are mounted for horizontal translation from one end of the saw table to the other by means of a servo controlled drive motor which is attached to a ball screw type drive so as to prevent backlash. The arbor is supported on a carriage way positioned vertically below the arbor and is stabilized by a second horizontally positioned carriage way. Each carriage way is attached to a single side of the support frame below the work piece support surface. The saw blade is driven by a constant speed motor having a variable speed transmission and gear box so as to permit selective adjustment of the cutting speed of the saw blade. The work piece is clamped on opposite sides of the cut and a precision work piece positioning apparatus is provided so as to further effectuate the cutting operation within a close tolerance range.
