A machining center type machine tool which is a four-axis, horizontal spindle machining center with a carousel-type automatic tool changer and which is adapted to be controlled by a computer numerical control system. The machining center can perform a variety of machining operations, such as milling, contouring, drilling, tapping and boring, in both roughing and finishing applications. A rotary work table is operatively carried on two movable, perpendicularly disposed slide members to provide movement of the work table along both "X" and "Z" axes. A horizontal tool spindle slide assembly is slidably mounted on a "Y" axis on a twin column assembly. A rotary, carousel-type combination tool storage and tool changer, holding twenty-four tools, rotatably mounted on a horizontal axis that is aligned and parallel with the axis of the horizontal tool spindle. The rotary carousel functions to automatically load and unload tools directly into the tool spindle at a tool exchange location. The tool spindle extracts the tools from the carousel, and inserts the tools back into the carousel after a cutting operation. The machining center includes a manually operated optional pallet changer fro automatically loading a pallet carrying a new workpiece onto the work table, and unloading the pallet with a finished workpiece from the work table. The tool spindle is provided with automatic mechanical spindle positioning for each spindle stop. |
