Self Reversing Tapping Attachment GNCK

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)
• no malfunction due to contamination or through too much gap in the stop arm - reduced down time of the machine, prevention of collision / no damage from displaced stop arm
