The Sertom hydraulic calender , with a useful length of 2.5 metres 14 mm thick . It is a used model, but in excellent condition, which still offers high performance thanks to the construction quality and the technology applied by Sertom , a brand recognized for its reliability in the calendering sector.
Looking at the machine, you immediately notice the massive and well-designed structure, a sign of the typical quality of Sertom . The calender is equipped with two lower rollers with a diameter of 300 mm and a slightly larger upper roller 318 mm , which allow homogeneous and precise bending. The system is powered by a 22 kW for the rotation of the rollers, while the movements of the machine are guaranteed by an additional 5.5 kW . The calender castle is supported by an additional 2.5 kW , contributing to the overall stability and efficiency of the machinery.
The machine measures 600x190x210 cm (height included), therefore it requires adequate space for installation. The overall weight, equal to 15,500 kg , testifies to the solidity of the calender, which is built to last and work intensively on heavy materials.
The mechanical characteristics of the Sertom hydraulic calender allow processing of sheets with a maximum thickness of 14 mm , with the possibility of obtaining precise and well-calibrated curvatures thanks to the hydraulic control of the rollers. The invitation facilitates the insertion of the material into the machine, reducing the risk of errors during the initial processing phase. The powerful power supply, with a 22 kW , ensures that the rollers rotate with enough force to process tough metals such as steel and aluminium, whilst maintaining good precision.
Using the Sertom calender is an intuitive process, but requires some technical expertise to achieve optimal results. First, you place the sheet metal between the bottom rollers and the top roller, using the gauge to align it properly. Once the sheet metal is in place, you adjust the rollers through hydraulic control to begin the bending process. 22 kW motor drives the rollers, which begin to roll and gradually bend the material. For greater precision, the movements can be finely adjusted with the 5.5 kW of power dedicated to the movements of the structure.
Among the accessories that can be combined with this Sertom bending machine , there are CNC control systems to automate the process and obtain greater precision, as well as customized rollers for specific bending needs on particular materials. Furthermore, it is possible to install advanced sensors and safety devices to ensure that the manufacturing process complies with the latest regulations.
To calculate the force necessary to bend a sheet metal with a maximum thickness of 14 mm , a classic formula can be used:
F=K×S2×LDF = \frac{K \times S^2 \times L}{D}
Where:
The Sertom calender is ideal for working on various metallic materials such as:
Thanks to its power, it is able to effectively bend sheet metal with different levels of resistance, up to a maximum thickness of 14 mm .
Good maintenance is essential to maintain high performance. It is advisable to carry out regular lubrication of the rollers and periodically check the hydraulic components. CE safety regulations , but if it is not certified or compliant, it is possible to update it by installing safety systems such as photoelectric barriers or automatic blocking systems to avoid accidents during operation.
When evaluating a used calender , it is important to check the wear of the rollers and the condition of the hydraulic system. In the case of Sertom , the brand is synonymous with quality and reliability, so a machine like this, well maintained, represents an excellent investment. Always check the documentation to ensure that the machine has been regularly serviced and that there are no signs of structural damage.
The Sertom calender is particularly popular in the metalworking sector, in the production of metal structures, in the manufacture of tanks and pipes, as well as in the naval sector. Its versatility and robustness make it ideal for precision work on sheets of various thicknesses.
Buying a used Sertom calender is an excellent choice for those who want a reliable machine without having to invest large sums for a new model. Sertom brand guarantees that, even after years of use, the machine maintains its performance, making it an advantageous deal both in economic terms and in operational efficiency.
