Machining accessories Expansion of workpiece clamping portfolio: Hainbuch acquires Vischer & Bolli
By acquiring Vischer & Bolli Automation, the German manufacturer of high-precision workpiece clamping equipment Hainbuch has not only expanded its expertise in the field of automation, but now offers a wider range of stationary workpiece clamping devices.
With the acquisition of Vischer & Bolli Automation in Lindau, Hainbuch expanded their range of workpiece clamping devices in the stationary field.
The company's previous product portfolio for turning, milling, EDM and grinding already covered a wide range of workpieces. With the acquisition, the group is also able to offer custom solutions for workpieces of up to 100 tons or 10 to 20 metres in length, large-scale projects like this have already been completed. The range of stationary devices has been considerably extended, the company announced. Many stationary clamping devices are available from stock and the modular design of the zero-point clamping system offer a wide range of solutions using standard components, while specific solutions can also be created in accordance with customer requirements.
The zero-point clamping system, which is screwed onto the machine table, serves as a base for fast change-overs. This is available in pneumatic and hydraulic versions and is used for manual and automated solutions. To clamp the workpiece on the base, a vice [mechanical, pneumatic or hydraulic], clamping tower, modular clamping device, modular clamping system, magnetic clamping plate or a special device can be used depending on the customer´s requirements. This means that an optimal and economic overall solution can be offered for every workpiece, regardless of shape or size. The zero-point clamping system has an accurate clamp and thus ensures maximum back force. At the same time, it is absolutely low-wear and maintenance, as it has only three moving parts. Handling and push-off functions are integrated in the system. The modular design ensures maximum flexibility and huge time and cost savings in production. With the universal interface, the setup is done off the machine so no production time is lost.
Standardized locking plates and mounting cylinders for the zero-point clamping system
The patented collet style lock ensures easy insertion and removal of the workpiece pallets. With an insertion force of up to 30 KN, a vibration-free, positive and non-positive connection between the zero-point clamping system and the workpiece is guaranteed. Tailor-made custom solutions help to make optimum use of machining potential. Direct installation on machine tables, pallets or fixtures is achieved cost-effectively with installation cassettes. The zero-point clamping system can be expanded with optional air blow, support and locking control or external feeds.
