Applications that require minimal batch sizes, high precision requirements, and complex geometries need high-tech solutions to get the job done. SCHUNK’s new modular system for direct workpiece clamping is ideal for complex jobs.
Modular clamping columns enable direct clamping of molding plates, freeform parts, and other workpieces on the machine table within seconds, without additional clamping devices or interfering contours. The clamping pillars guarantee collision-free processes, a defined clamping situation, and a reliable simulation of the machining. In addition, changes in the workpiece can be implemented quickly due to the high precision of this clamping solution.
The modular system consists of VERO-S WDB base modules for the machine table, VERO-S WDN clamping modules (ø 99 mm), and freely combinable VERO-S WDS stacking modules. The latter have a standardized height of 30 mm and 50 mm, to allow fine graduations of 10 mm in the height of the clamping columns starting at a height of 80 mm. The connections between the single modules are designed for high machining parameters, with a high pull-in force of up to 25,000 N. To ensure distortion-free workholding, height differences can be compensated by a steplessly adjustable, hydraulically clamped VERO-S WDA compensation element.
All interfaces feature scope-free taper centering, which ensures a repeat accuracy of <0.005 mm between the single components. An integrated air feed-through allows actuation of the clamping modules and monitoring of the presence of a workpiece. The workpieces themselves remain securely clamped even if the pressure in the air system should suddenly drop. A pneumatic system pressure of 6 bar is sufficient for opening the clamping modules. For a longer life and increased process reliability, all functional parts such as the base body and slide assemblies are made of hardened stainless steel, are absolutely corrosion-resistant, and very easy to clean.
