Lathe chuck - ø 6 - 300 mm | SG
With the SG clamping System, a split clamping bush with special buttress threads is screwed onto the main body. By introducing an axial force, the clamping bush moves in the direction of the force. This causes the clamping bush to expand radially, due to the angle of the threads. The workpiece is clamped.
The transferable torque and the clamping rigidity are increased by the axial force components being applied to the workpiece. Even workpieces being machined with a large chip cross section can be safely clamped!

Lathe chuck - ø 6 - 300 mm | SM
The SM diaphragm clamping system is used for special productions, such as high-precision gear wheels. This process involves keeping the concentricity deviations between the reference circle and the seating bore as small as possible.
The clamping element is a washer-shaped diaphragm, preferably with three clamping jaws. If the application involves thin-walled workpieces, the diaphragm can also be designed with four or six clamping jaws. These are either cut out of the diaphragm or screwed onto it.
The SM clamping system facilitates clamping the gear wheel in the reference circle in order to machine the seating bore. Applying an axial force to the diaphragm causes it to deflect. This causes the clamping jaws to move axially and simultaneously open radially. The gear wheel is released.
Be reducing or eliminating the axial force, the diaphragm returns to its original position due to its own spring-like property. The gear wheel is clamped both radially and axially.

3-jaw chuck / lathe / through-hole
The design and quality of this chuck makes it ideal for conventional and also high speed applications. Unit costs are reduced because of larger through bores, wide jaw movement and high operating speeds without counterbalance.

3-jaw chuck / hydraulic / lathe
A range of compact power chucks with integral hydraulic cylinders designed for CNC lathes with ports for chuck actuation through the spindle walls. The design obviates the need for a drawtube enabling the full machine spindle bore to be utilised for maximum bar capacity. Collet pads may be fitted to the base jaws for first operation bar and shaft turning. The chuck body doubles as a cylinder and, being sealed inside, the mechanism is automatically lubricated. A controlled flow of fluid to the jaw ways provides base jaw lubrication. In the event of hydraulic failure, the mechanism is unique in being completely self-locking.

3-jaw chuck / lathe / pneumatic - 1300 - 3000 rpm
A range of pneumatically-operated power chucks with incorporated cylinders. The self contained chuck simply bolts onto the lathe spindle nose - no rear-mounted cylinder or drawtube is required, just airline connections from the control unit. The chuck's simplicity allows rapid interchangeability with standard manual chucks or collet chucks. Ideal for small/medium batch component production on centre lathes, capstan and turret lathes or NC machines. Suitable for all bar and chucking work.
