The ZG-4000/0.8 bending machine is a model designed for processing flat sheets up to 4 meters in length!! It is equipped with three cylinders lifting the pressure beam and two cylinders lifting the bending beam, which gives it a very wide range of operating capabilities. It is manufactured primarily for sheet metal shops and ventilation companies working with sheets up to 4000 mm in length. Achieving such bending machine performance parameters is possible thanks to the use of strong and durable (35 mm thick!) side mechanisms, as well as significantly increased cross-sections of the working beams. Additionally, the side mechanisms feature brass bushings with direct lubrication in every rotating element, which increases the machine’s service life.
Thanks to the high lifting capacity of the pressure beam (up to 100 mm!), the bending machine is useful for manufacturing ventilation ducts. The ability to work with roller shears further enhances its functionality.

The main working elements of the bending machine are the beams: fixed, pressure, and bending.
The pressure beam is a movable beam used to secure the sheet metal in the desired position. It is raised and lowered using a lever. Three gas cylinders assist in raising the pressure beam. The pressure beam is designed so that its upper part serves as a guide for the circular shears.
The bending operation is performed by rotating the bending beam to a specific angle using a handle. Two gas springs assist in lifting the bending beam. A protractor mounted on the left side of the bending machine (as viewed from the front) indicates the current bending angle of the sheet metal.
The bending beam is adjustable relative to the fixed beam. This parameter affects the sheet metal bending radius, and its value also depends on the thickness of the sheet being bent.
The working beams are equipped with tensioners used to ensure the straightness of the working edges.
The bending machine components are manufactured on precision CNC machine tools.
The bending machine is coated with a double layer of high-quality paint—the painting process is carried out in a professional, heated, and ventilated paint shop.
