Abstract: A measuring and/or control system (1), to control for example a machine tool, comprises at least a first and a second unit, each comprising electronic circuits and at least one socket. The systems further includes a multipolar cable (8) containing a plurality of wires (8A) and having a first and a second end, each provided with a multipolar connector (9) adapted to be coupled to a socket of the first unit and second unit. At least one of the multipolar connectors of the multipolar cable is a fast wiring multipolar connector (12) provided with a first body (12A) and a second body (12B), adapted to be plugged into the first body. The first body comprises a support with two opposite faces, a first group of electrical contacts fixed to one of the faces of the support and adapted to be coupled to one of the sockets of the first or second unit, and a second group of electrical contacts fixed to the other face of the support.

Abstract: A measuring and/or control system (1), to control for example a machine tool, comprises at least a first and a second unit, each comprising a casing with a front wall, electronic circuits and at least one socket. The system further comprises a bridge connector (11) having a first multipolar connector (11A) and a second multipolar connector (11B), each of which can be coupled to one of the sockets in order to electrically connect the first and the second unit. In each of the first unit and second unit, the socket is positioned on the respective front wall and comprises planar electrical contacts. The first and the second multipolar connectors of the bridge connector are directed in the same direction so as to face the front wall of the first unit and the second unit and each comprise retractable contacts. The bridge connector comprises fastening elements for fastening the bridge connector to the front wall of the first unit and of the second unit.

Abstract: A data processing and transmission system (1) for a numerical control unit (2) adapted to control a machine tool (3), comprises at least one input channel (4) adapted to a transit of operational signals from or to devices present in the machine tool, electronic circuits configured to process the operational signals to make available on an output interface (5) control signals for the numerical control unit, a multipolar cable (8) having a first and a second end, each provided with a multipolar connector (9), a master unit having the output interface, a main processor, a memory and at least one socket (7A) configured to be coupled to one of the multipolar connectors, one or more slave units (6), each provided with at least one external port (6A) defining the input channel, a memory, a secondary processor, and provided also with a first socket (6B) and a second socket (6C), configured to be coupled at least to a first or a second connector of the multipolar connectors in order to interconnect the slave unit at l

Abstract: An apparatus for checking diameter and roundness of crankpins (42) in the course of the machining in a grinding machine, includes a Vee-shaped reference device (70), a gauging device with a movable feeler (67) associated with the Vee-shaped device (70) and a movable support (5, 40, 41, 60) device for the Vee-shaped reference device. The movable support device is coupled (5) to the grinding-wheel slide (1) and includes, in working condition, two parallelogram structures (40, 41) in series enabling substantially translation displacements of the Vee-shaped device (70).
