Composites Europe: 19. – 21 September 2017, Stuttgart (Germany)
In the spirit of ‘clamping with ice’
Composites Europe, the leading international trade fair for fibre composite technology, will once again be the showcase for innovative technologies and the meeting place for specialists from all over the world in 2017. This year we are presenting ‘clamping with ice’ for the second time, and not because we are running out of ideas, but because interest in this technology is growing more and more.
Conventional clamping technology reaches its limits when components are too small or too thin or, for example, have an air-permeable material composition. Clamping with ice, on the other hand, is a fastening technology that makes it possible to clamp even workpieces made of difficult materials or geometries. Conventional techniques fail, for example in the production and processing of plates made of sintered materials, because these plates cannot be clamped with vacuum without distortion. The same applies to air-permeable materials such as paper or plastic honeycombs or porous aluminium sponges, which are used in the aircraft supply industry, in rail vehicle construction and in truck bodies. The size of the components also quickly leads to the limits of feasibility. In medicine, in the production of implants or in microsystems technology, the smallest components are needed that have to be machined with pinpoint accuracy.
Using the system on a CNC machining centre is uncomplicated: During clamping, the workpieces are frozen securely and absolutely stress-free on a Kryotool clamping plate by means of water. The plate itself is held on the machine like a workpiece with conventional fastening elements. This means that the same high clamping force acts on the entire contact surface.
Components that have, for example, free-form surfaces or low mechanical stability are frozen in a recess in the clamping plate and can thus be fixed in any machining plane. Without time-consuming reclamping, 5‑sided milling, grinding or polishing can be carried out in a single operation. The powerful automatic defrosting system ensures that the workpiece is quickly released after the machining process.
Numerous users from a wide range of industries work with this technology on our CNC machining centres. We will be happy to present successful solutions to you in detail. You will find us in Hall 4 / Stand A29
