By its nature carbon fibre reinforced plastic is extremely light and extremely rigid, good reasons why it has been primarily used in the aerospace industry and for various high-performance sports. Now HAINBUCH has also discovered the advantages of this lightweight material and optimised it for their new chuck range. The results are chucks that consist of multiple plastic fibre layers that are successively embedded in an epoxy resin matrix. A complex process that requires a lot of experience and maufacturing sensitivity. The result is impressive: The drawbar actuated TOPlus chuck and the manually actuated TOROK clamps start the new product series in the machine tool area of lightweight constructions. These chucks allow faster acceleration and braking of the machine spindle. Thanks to the faster machine cycle times, productivity is increased. In addition, due to the low weight, energy consumption is reduced, set-up is extremely user-friendly, and the machine drive has a significantly lower load. And all this with increased strength and stiffness. The lightweight version of the manual-actuation MANOK plus stationary chuck is designed for use on milling machines and machining centers with low load weight. The aluminum flange, in conjunction with the carbon fibre base structure, allows a weight reduction of approximately two-thirds relative to the standard version. In addition, the lightweight construction variant of the MANOK plus substantially minimises the interference contour and offers impressive dynamic machining on 5-axis machines, and not just through low energy consumption and less centrifugal forces. Here as well the low weight lightens the machine drive and has a positive effect on positioning accuracy and is very easy to set-up.
