Abstract
Abstract A machine tool having an automatic changing means and which is constructed and arranged to carry out a variety of machining operations, such as milling, drilling, boring, tapping and the like. The machine includes a rotary, four-position index work table which is carried on two movable, perpendicularly disposed slide members to provide movement of the work table along X and Z axes. A tool spindle assembly is slidably mounted on a ''''Y'''' axis between two column members with a tool spindle, spindle drive motor, gear box, tachometer and resolver mounted in axial alignment with each other for movement as a unit along said Y axis. A tool storage conveyor is disposed horizontally on said column members above the tool spindle assembly and for moving tools into a tool changing position above the tool spindle. A tool changer means is mounted between the column members and between the tool spindle assembly and the tool storage conveyor for automatically transferring tools directly between the tool storage conveyor and the tool spindle.
