Abstract: An automatic cutting and press-fitting apparatus 10 includes a wire transporting unit 25 for transporting a wire W to at least a cutting and peeling unit D and a terminal press fitting unit E, and a transporting and clamping unit 62 for transporting the wire W to the terminal press fitting unit E and transporting the wire W after press fitting. The wire transporting unit 25 has a nozzle 43 for guiding the feeding of the wire W. In the apparatus 10, a wire guide plate 71 is disposed between the nozzle 43 and the transporting and clamping unit 62 and is capable of moving in the vertical direction by a pneumatic cylinder 72. With the vertical movement of the plate 71, when the unit 25 is returned from the unit E to the D, it is possible to prevent the wire W from being caught on the cutting and peeling unit D incorrectly. Further, when drawing the wire W to the unit 62, the erroneous pinching of the wire W can be prevented by the plate 71.

To increase the accuracy when machining a workpiece, there is a plate, which is to be connected to the face and is provided with spatial references on the front side, and which has a central passage opening to receive a tension rod, connected to the backside of the work-holding fixture, and a bolt, whose front end can be coupled with the tension rod and whose rear end can be connected to the collet.

Abstract: A machine tool has a frame supporting a vertical gantry which is driven at the top and bottom sides of the gantry such that the opposed, normal magnetic forces between stator coils and magnets are substantially equal and are self-cancelling. This reduces normal magnetic forces that increase friction, and this prodes symmetry along an X-axis. A spindle-carrying saddle travels in a vertical slot in the center of the gantry with left and right linear motors mounted on opposite sides of the gantry. The linear motors are identical so that opposed right and left-hand, normal magnetic forces are self-cancelling. This provides symmetry along the vertical Y-axis. A spindle and ram are mounted on the saddle and are driven by at least one linear motor to travel along the Z-axis. The symmetry and cancelling of normal, magnetic attractive forces reduces the weight and the amount of forces needed to accelerate the gantry in the X-direction and the saddle in the Y-direction.
