Customer opinion "That is how we amortised our investment of 80,000 Euro after a short time" Modellbau Hochstein GmbH & CO. KG benefits from the efficiency increase by GARANT ZeroClamp A significant part of the manufacturing costs is accumulated with the factor time, because time is money. To considerably reduce the setting-up times for the machining of complex component parts, Modellbau Hochstein GmbH & Co. KG looked for appropriate technological solutions - and decided in favour of GARANT ZEROCLAMP. With the innovative zero-point clamping system, setting-up times can be reduced by 95 per...

The following conditions have been defined for a new zero-point clamping system: ■ No costly maintenance intervals ■ Preferably only one clamping stud type ■ Outstanding price/performance ratio Component part during milling (Joachim Hochstein) GARANT ZeroClamp: Latest clamping technology An exhibition of the Hoffmann Group called the company's attention to GARANT ZEROCLAMP. "The innovative functional principle of the zero-point clamping system was demonstrated to us and we were quickly persuaded that we could manage even complex clamping tasks with it." Reduced setting-up times, increased...

Easy handling and quick amortisation Whether turning, milling, measuring or grinding - the zero-point clamping system can be integrated into all applications and individual manufacturing processes without any problems due to its uncomplicated technology. All components are made of stainless or corrosion-resistant steel and are simply and robustly constructed. The clamping system convinces additionally with its low maintenance: Leakage cannot occur, because the system is not operated hydraulically. Other systems need several clamping studs to adjust the workpiece accurately, GARANT ZEROCLAMP...
