Special applicationsAutomatic device for small size taps(M3-M30) driving on a grinding machineon centers• Driving by means of clamping without influencing the positioning got bycenters• Quick set-up• Feeding both pneumatic and hydraulic• Loading both manual and automatic• Specific sizing to allow passage of grinding wheels for multidirectionalmachining• Centrifugal force balancing• Protection against dirtIn the picture above: Device with 120 mm diameter with jaws sizing to allow grinding wheelspassage. System realized to clamp a tap range from M3 up to M30, suitable for bigger sizetaps too.Device is provided with built-in cylinder for automatic movement of the jaws, feeded by reardistributor.Special centering and stirrupping clampingsystem for CNC turning-milling-grindingmachines suitable for automatic loadingCentering clamping on hole and stirrupPEL workpiece detection systemLong stroke expander. 7 mm on diameterRepeatability accuracy lower than 0.005 mmQuick change centeringQuick change stirrupsSystem driven by double cylinderHigh rotation speedChuck descriptionThe system is complete with 2 independentmechanisms.First one is moving the central expanderhaving stroke mm7 on diameter, centeringthe workpiece from the inside.Second one is linked to a moving platedriving 3 rotating and stirrupping shafts.These are clamping the workpiece grantingstiffness during machining.Both systems are driven by a double cylinder.There is a PEL detection system checkingthe right positioning of the workpiece by therobot.The change of workpiece type is very fastthanks to quick coupling systems of differentcomponents.8
