A multifunction, compact machining center has a work spindle which can rotate at high speed, or controlled by a C axis servo driver, and a frame-shaped tool magazine, which is composed of a standing part and a rotatable part. Arranged on the standing part are enough internal and external turning tools to complete all turning processes on one workpiece. Driven tools are held on the rotatable part to do drilling, boring, milling, gear hobbing, grinding, lapping etc. on the same workpiece at arbitrary angles. Additionally, work units for quenching, laser machining, gear shaping, bevel gear cutting, measuring, loading and unloading can also be employed on the tool magazine. By means of movements of the tool magazine relative to the work spindle in the plane perpendicular to the Z axis, each cutting tool or working unit can be put into the working area of the workpiece sequentially so as to complete all machining, measuring, loading and unloading. This invention replaces several machining centers or an FMS, and advantageously, this compact machining center avoids accuracy loss and waste of time caused by repeated clamping.
