Abstract: A tool presetting fixture is disclosed for use with cross-slide type tool holders which are usable on a multiple spindle automatic machine tool. The tool holder has a tool holding pocket to hold a cross-slide type tool with a tool tip. The fixture has a base with a first gage surface mounted for movement parallel to the base to gage the spindle centerline height of a tool tip in the tool holding pocket. The fixture also has a rear wall on the base which has a second gage surface perpendicular to the base. Gage means is provided to gage the distance from this second gage surface to the tool tip and screws are provided in the tool holder and acting on this second gage surface to obtain a gaged distance of the tool tip from a reference surface of the machine tool to establish a predetermined longitudinal dimension on the workpiece.
