ABSTRACT:
A surfacing and boring machine for reconditioning engine blocks has a front stationary work table, a traveling column on rails provided by an elongated rigid base, a power head unit on the column adjustable in an air float condition to move an overhanging spindle forwardly and rearwardly, and mechanisms in the power head unit to independently move a spindle carrier vertically and to rotate the spindle at selected speeds. Clamping devides are provided to independently clamp the power head unit to the traveling column and the column to the base rails. A quick-change unit is located in the spindle for the tools.
