Hoffmann Group Teels to maktyau better 47 ZeroClamp zero-point clamping system The centrepiece Only 8 parts for reliable clamping force. Pure productivity Revolutionary increases in efficiency, precision, and variability with the innovative zero-point clamping system. Increasing the machine running time is a key route to success. GARANT ZeroClamp is the efficient zero-point clamping system: it combines high speed, power, and very high precision to achieve reduced set-up times, change-over times, and ancillary times by up to 90%. The key advantage Thermal symmetry - always towards the centre. The absolute zero point: Compensation for thermal expansion is always symmetrical about the centre axis. Special zero-play clamping cones for low-vibration operation. No sword pins, no floating pins. Repetition accuracy 2.5 tim Conventional technologies compensate thermal expansion using floating bolts - which is particularly inaccurate for workpieces that are rotated around a central axis. With GARANT ZeroClamp absolute thermal symmetry is provided at all times due to the central zero point. Absolute zero point by thermal compensation in relation to the zero point and axis of rotation. Precision taper on insertion the resiiientiy sprung taper of the socket expands slightly towards the flat (ace. Play-free, centring damping within the hardened steel cone. Locking unit. Low-wearing technology an air hose and damping plates provide the necessary damping force. Air connection can be released. Radial springs mounted in NBR. All components are made of stainless steel, or steel with corrosion protection. Axis of rotation The drawbacks of classic zero-point clamping systems: Axis at 0° Axis at 180° Free pins Free pins Zero pin Floating pin Fixed position In conventional systems, thermal compensation can be achieved only by using different types of pins. Red arrows = displacement The example of a circular axis clearly shows how the error leads to deviation from the axis of rotation. 1 s A Only 1 stud type needed. One basic unit - outstanding flexibility The zero-point clamping system for a wide range of applications. & 832
