ABSTRACT:
A recess attachment with preset quick change tooling for use on a multiple spindle automatic machine includes a base formed and adapted to be mounted at a work station on an automatic machine. The base is movable in a defined direction during a machining operation and has a slide mounting surface in a plane forming a small acute angle with the direction of movement. A slide is positioned on the slide mounting surface and there are springs attached to the base and the slide inhibiting relative movement therebetween. A tool holder is removably mounted on the slide and there is an adjustment member positioned on the tool holder and a cooperating stop on the slide. The tool holder has a tool receiving opening and there are means for fastening a cutting tool in the opening. The base and slide move in unison to a precutting position. Further movement of the base relative to the slide causes the slide and the cutting tool mounted thereon to move in a direction generally perpendicular to base movement to cut a recess in a workpiece.
