Abstract: A multifarious boring device includes a work table and a head with a variety of machine tools or cutters. The work table and the head are controlled by a computer through a shifting device and a power device. The computer computes distances and directions between the cutters and working points on a workpiece on the work table. Thereby, the shifting means controlled by the computer shifts the work table having the worked material thereon. The power device controlled by the computer powers one of the cutters. Codes of the type of holes and working points are fed into the computer. Thereby, a desired hole can be made at a desired point on the workpiece, and different patterns can be made in different types of workpieces.

Abstract: A multi-station machine tool wherein the bed of the frame supports two spaced-apart upright columns and the columns support an indexible shaft for a turret which is disposed between the columns. The turret has several sets of clamping jaws for elongated rod-shaped workpieces which are introduced and removed at a first station or which are introduced at a first station and removed at a second station. The number of stations may greatly exceed two, and each column supports several spindles including at least one rotary and axially movable tool spindle and at least one axially movable and preferably rotary work spindle. Each spindle in one of the carriers is coaxial with a spindle in the other carrier, and the turret indexes the workpieces in such a way that they come to rest between successive or selected pairs of coaxial spindles.
