The system offers process security thanks to its precise, short taper centring and self-locking mechanism. This guarantees repeatability of <0.005 mm, says WNT.
The clamping slides are first closed by spring force, locking the clamping bolt via 15° angled surfaces, before the pneumatic power function supplies the piston surfaces with compressed air to increase the clamping force by up to 300%. According to WNT, as a result of this 25 kN clamping force, it is possible to utilise higher cutting data.
Once the mechanical locking system engages via the spring assembly, it is self-locking and form-fitting, meaning a compressed air supply is not required during machining. To release the clamping pressure, compressed air applied at a maximum pressure of 6 bar is sufficient to open the clamping modules.
The base plates, clamping bolts and clamping slides are made from hardened stainless steel.
