Hainbuch No contamination when clamping rigid, large parts
Germany – Hainbuch’s Spanntop Nova workholding system now provides three different chuck options: the combi pull-back with an end-stop facility, the combi dead-length with end stop and the modular chuck pull-back version for bar work.
All three have different features to meet customers clamping requirements, the company says.
Resistant against contamination from coolant, swarf and dust, the clamping head of the Spanntop Nova has vulcanised seals that protect the system from any ingress from the work area. The vulcanised clamping head also minimises vibration, Hainbuch claims.
The rigid clamping of large workpieces in the chuck is said to pose no problem to Nova. According to Hainbuch, the jaw module and clamp parts can be fitted up to 215 mm in diameter. Internal clamping is just as easy as the mandrel system can be rapidly changed to fit directly into the chuck. Also, by utilising the company's Centrotex positioning technology, no radial adjustment is necessary. This allows for precision and clamping forces to be retained whilst reducing changeover times. The changeover time is further reduced with just 3 screws holding the base end-stop – a feature that is said to provide the change from bar work to billet work in just over 1 min.
The Nova has a large contact area between the collet and chuck taper. This is said to provides accurate clamping and minimal component deformation when clamping short parts.
