Combining absolute precision with maximum performance

Due to the unique lever system of the BSTA-series, the load acting on the ram is distributed. This load distribution, together with the absolute minimum clearance in the main and connecting rod bearings, are the backbone for the long life and high precision of the machine.

In order to prevent deflection of the tool’s upper die – due to excentric loads – the ram guide elements are placed in the same plane as the strip. This decidedly increases the tool’s service life.

Each of the hardened and ground ram adjustment screw-spindles only need to absorb 20 % of the load due to the lever system. This unique design permits the ram to be adjusted during the punching operation while maintaining closest tolerances.

First-punch accuracy and braking angle

The first-punch accuracy of our punching presses, which ensures constantly high production quality from the first to the last punch, is a feature not to be underestimated. Furthermore, the compact and extremely fast-reaction brake and clutch unit ensures minimum braking distances – a further indicator of absolute precision and maximum performance.

This is supported by the extraordinarily acute braking angle, which guarantees an immediate stop of the punching process – triggered for example by the tool monitoring function. These components avoid unnecessary repair costs associated with punching tools.
