The coupling device is designed and constructed so as to permit a simple mounting of even heavy tools to the output shaft of the motor, and a reliable connection of the tool and drive.

Abstract: A plunge base router for use in an upright and an inverted position is disclosed. The router includes a depth adjustment mechanism, a depth stop mechanism, a post lock mechanism, and a return spring defeat mechanism. The depth adjustment mechanism includes a course adjustment mechanism and a fine adjustment mechanism to set the cutting distance of a bit. The course and fine adjustment mechanisms are usable in both the upright and inverted positions and the fine adjustment mechanism is operable without being reset throughout the full range of motion of the plunge router. The depth stop includes a mechanism for locking the end of a rod on the housing to the base in order to set the relative position in between the housing and the base. The depth stop also includes a plurality of steps for engaging the rod and permitting incremental passes of cutting at different depths with the router.

Abstract: The invention relates to a machine tool comprising of at least one tool spindle which can be moved and positioned in at least one working plane by a movement system. It is proposed to produce the movement system from at least two guide rods connected to one another in an articulated manner by a guide rod joint, and that in the process, the free ends of the guide rods can be moved in opposite relative directions towards and apart from one another and/or in the same direction as one another.

Abstract: A machine tool comprises a spindle head displaceable in two orthogonal directions. The spindle head supports a plurality of main spindles and at least one common central driving gear. The spindle head is suspended by means of three flexible rods and a stationary main drive motor is coupled to the driving gear via a flexible shaft.To be used for milling recesses into plastic cards, the recesses being dimensioned to receive electronic chips.

Abstract: A divided milling cutter comprises a first cutter half and a second cutter half which are adjustable in relation to each other with respect to their mutual distance and are both connected to a first, common, hydraulic sleeve which has an internal, annular pressure chamber and is threadable on to and securable to a cutter spindle or the like. To make possible a continous or step-less variation of the distance between the cutter halves in a simple way even when they are mounted on the cutter spindle said second cutter half is fastened to a second sleeve which is in threaded engagement with a third, threaded sleeve having a substantially annular flange which abuts an end of, or shoulder on, the first sleeve.

Abstract: A mechanism for individually positioning a drilling head in a multiple head drilling assembly. The assembly includes a plurality of spindle blocks arranged in side-by-side relation, and a spindle that is adapted to carry a drill head is mounted for rotation and axial movement in each block. Each spindle block is mounted for individual lateral movement in a direction normal to the axis of the spindle on guide rods, and is driven laterally by a rotatable lead screw that extends parallel to the guide rods. A recirculating ball nut is associated with each spindle block and is engaged with the lead screw. A clamping mechanism acts to selectively clamp each nut to the respective spindle block and by clamping the nut to the block, the spindle block will be moved along the guide rods on rotation of the lead screw, and by disengaging the nut from the respective spindle block, rotation of the lead screw will cause free rotation of the nut without movement of the block.

Abstract: A staircase stringer fabricating apparatus includes a structural machine frame having a carriage moveably mounted with respect to the frame for supporting an elongated stringer work piece. A track mounted upon the structural frame defines a guide for the carriage so that the carriage can move on a controlled path with respect to the frame. Material working stations, such as wood routers, welding torches or the like are spaced upon the machine frame for simultaneously preparing the work piece with selectively spaced apart tread assembly positions that define the horizontal stair step positions (including the spacing and angular positions) upon the stringer during use. The tread positions are preferably formed responsive to the movement of the carriage and work piece upon the track along the controlled path so that the work stations traverse the work piece.
