The ZCP 020 manual cutting press employs the bent-lever principle. Attractive detail solutions allow accurate, convenient, energy-saving operation. The bent-lever length was selected to achieve up to 30 % higher cutting force in the starting range than with conventional presses. This cutting-press features particularly operator-friendly design and can be placed on any workbench or laboratory table or mounted at optimum height on a suitably sturdy wall. In addition, particular emphasis has been placed on simple, quick, and exact height adjustment of the compression die to accommodate varying heights of different cutting blades.
