摘要： An apparatus for balancing a rotating body, in particular the grinding wheel of a grinding machine, comprises an assembly secured to the grinding wheel and rotating with it, with masses having an adjustable arrangement, electrical motors for controlling adjusting movements of the masses, and electrical circuits with a microprocessor unit. A transceiver terminal between a control unit and the rotating assembly provides a first contactless transmission channel for inductively coupling a fixed power source to the rotating parts, and a second contactless transmission channel for transmitting information in both directions. The second transmission channel may comprise optoelectronic devices.

摘要： The machining of mechanical pieces in a grinding machine is controlled depending on in-process and post-process measurements of the pieces. The post-process measurement is carried out by using the same in-process measurement means, with the provision of different zero references for the two types of measurements.

The signal is used for controlling the feed speed. An apparatus for controlling and regulating the working cycles of a machine tool including a measuring device for the measurement of the sizes of the workpiece being machined, a stepping motor, a digital counter, a digital analogue converter and adapter responsive to the position of the tool relative to a reference position, a differential amplifier, a program unit for programming the feed speed of the tool and a control unit for varying the feed speed. The stepping motor, digital counter, digital analogue converter and adapter responsive to the position of the tool and the measuring device are connected to the differential amplifier adapted to provide a signal responsive to the elastic strains suffered, during the machining, by the tool, workpiece and kinematic chain, due to the tool thrust. The output of the differential amplifier is connected to the program unit for varying the feed speed of the tool depending on the elastic strains.
