Self Reversing Tapping Attachment GNCN High performance tapping attachments with integrated reversing gear APPLICATION Application: tapping, roll forming Machine type: machining centres and special purpose machines FEATURES - self reversing gear - direct collet location - damping elements between drive key in the spindle and the coupling sleeve - balls used in the couplings elements - hydrostatic pressure compensation for IC version - constant tapping speed (through built- in reversing gear) - exchangeable drivers BN17… - built-in length adjustment screw - sealed, stable version of the stop arm ADVANTAGES - reversing of machine spindle not required - shortest processing time possible, minimum time saving 200 – 400 ms per thread, substantially less electrical power consumption - high concentricity - better life time of the tool, reduced wear, less unbalanced mass - avoiding premature wear - less maintenance intensive - exact disengaging point - exact thread depth, high repeat accuracy - no axial movement of the spindle into tension, even when the coolant flow is blocked - no risk of collision through extended tool - ideal cutting conditions - longer tool life time - positive torque transmission of the tap and of the driver in the spindle - no twisting or slipping of the tap in the collet - taps can be set to the required length - no input data error of tool length in machine offset (no risk of collision)
