Bilz 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)
