For rotating components, there’s the Hainbuch Maxxos mandrel system that borrows hexagonal clamping geometry from its TOPlus chuck range, in so doing improving clamping forces and sensitivity to contamination, for internal diameter clamping. This mandrel system is available for demanding workholding applications in diameters from 10 mm to over 150 mm.
Also showing is the Spanntop Nova workholding system. It provides rigid clamping of large workpieces: customers need only fit the jaw module to clamp parts up to 215 mm diameter. Internal clamping is carried out by changing over to the mandrel system that fits directly into the Nova chuck. Hainbuch's CentroteX positioning technology removes the need for radial adjustment.
The Spanntop Nova now comes in three different chuck options: the combi pull-back with end stop facility, the combi dead-length with end stop and the modular chuck pull back version for bar work only. To resist contamination from coolant, swarf and dust, the clamping head of the SPANNTOP Nova has a vulcanised seals.
The TOPlus range is also out in force. An innovation from Hainbuch’s R&D department permits 25% higher clamping forces whilst utilising the same clamping cylinder used in the Spanntop chuck range. The TOPlus incorporates a pyramid arrangement of glide surfaces to make this possible. The clamping head rests with full-surface contact in the TOPlus chuck body.
Hainbuch’s new thin-walled and lightweight carbon fibre product range also makes an appearance. These products feature carbon fibre reinforced plastic (CFRP) embedded in a plastic matrix in multiple layers, reducing the weight of the clamping device by more than 70 % and therefore increasing spindle acceleration by 30%. The result is a high-strength composite material in which strength and rigidity in the fibre direction is much greater than it is transverse to the fibres. Hainbuch's next generation of lightweight clamping devices have a static radial clamping force of up to 170 kN.
