The key advantage Thermal symmetry - always towards the centre. i The absolute zero point Compensation for thermal expansion always symmetrical about the centre axis. i Special zero-play clamping cones for low-vibration operation, i No sword pins or floating pins. 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 resiliently sprung taper of the socket expands slightly towards the flat face. Garant ZeroClamp zero-point clamping system Pure productivity Revolutionary increases in efficiency, precision, and variability with the innovative zero-point clamping system. Increasing the machine running time is one key 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 centrepiece Only 8 parts for reliable clamping force. ( Free of play, centric damping in a hardened steel cone. Radial spring embedded in NBR. All components are made of stainless steel, or steel with corrosion protection. Q Locking unit ) Wear-free technology; an airhose and clamping plates provide the required clamping force. O Air connection for release. a 1 A Only a single stud type needed. One base unit - immense flexibility The zero-point clamping system for a wide range of applications. 732 Main catalogue Hoffmann Group 46 The drawbacks of classic zero-point clamping systems Axis at 0° In conventional systems thermal compensation can The example of a circular axis clearly shows how the error leads be achieved only with certain types of pins, to deviation from the axis of rotation.
