Hainbuch, a global high-precision work-holding supplier, is expanding its range of stationary workpiece clamping devices with the acquisition of Germany-based Vischer & Bolli Automation, itself a workpiece clamping technology and automation specialist.

Hainbuch’s portfolio of workholding equipment for turning, milling, EDM and grinding already caters for a wide range of workpieces, but it can now provide custom solutions for workpieces of up to 100 tonnes or up to 20m in length.

The company can now offer a zero-point clamping system with a modular design to offer a wider range of solutions that use standard components. This modular platform, which can be screwed onto the machine table to facilitate fast changeovers, is bolstered by the option to offer bespoke customer-specific solutions to accommodate all workpieces, regardless of shape or size.

Both pneumatic and hydraulic versions can be developed with both manual and automated configurations available. To clamp the workpiece on the machine base, a vice, clamping tower, modular clamping device, modular clamping system, magnetic clamping plate or a special device can be selected.

The system also has a universal interface and an accurate clamping mechanism that maximises clamping forces. The low-wear and maintenance system only has three moving parts, extending service life and reducing service and maintenance requirements.

Additionally, the handling and push-off functions are integrated into the system and the modular design ensures maximum flexibility to generate significant set-up, time and cost savings.

With standardised locking plates and mounting cylinders for the zero-point clamping system, the patented collet style locking mechanism ensures easy insertion and removal of the workpiece pallets.

With a clamping force of up to 30kN, the vibration-free connection between the zero-point clamping system and the workpiece is guaranteed.

Direct integration with machine tables, pallets or fixtures can be achieved cost-effectively with installation cassettes and the zero-point clamping system can also be expanded with optional air blow and the integration of support and locking control or external feeds.
