Sawing systems

Circular saws designed for specific requirements are a Hertwich specialty. Take for instance our Hertwich billet saw. It’s an extremely robust short-stroke model. Our objective during design/engineering was to achieve top vibration absorption and optimum blade life. That’s why the main components such as the machine bed, saw blade carriage, and clamping head are made of steel / concrete composite.

You also benefit from efficient energy transmission (minimum energy loss) and lower noise emission because we implemented an HDL tooth chain drive rather than a conventional gearbox.

Position transducers improve the forward and return action of the saw chariot for faster production rates. Also included is feed control for better performance. This function limits the cutting feed according to the rated amperage. The cutting parameters for various alloys and billet diameters are stored in the data management system to ensure user-friendly operation. Upstream of the saw, ultrasonic inspection equipment identifies faulty log sections. Then they are removed and scrapped at the saw with the help of log tracking data – a special feature of Hertwich control software.
