Crippa 170HE
Heavy processes are no longer a limitation
The Heavy BWT series was created to process tubes with very large diameters: these machines can hold heavy loads and and withstand stressful production cycles. This series offers a range of multistack or single stack tube bending machines, and both versions are multiradius. All have last generation absolute servomotors with integrated feedback and diagnostics. Full Electric axes driven by CNC Siemens 840D sl run these machines. Despite the large size, these tube bending machines ensure reduced energy consumption and present an ergonomic layout that guarantees high level comfort for the operator.
Description
The 170HE is a completely electric tube-bending machine designed to process mild-steel tubes with a diameter and a thickness of up to 170mm and 12mm, respectively, using Direct Drive technology. Its fifteen axes with Fully Electric Technology are managed by Siemens SINUMERIK 840D sl for maximum precision. Equipped with the latest generation absolute servomotors with integrated feedback and diagnostics, this massive tube bending machine has a vertical stroke of 950 mm. Therefore, several levels of tools can be installed for multistack and multiradius bends in the automatic cycle. The machine’s rigidity and precision renders it ideal for heavy-duty processing of tubes with a relatively large thickness (6” sch.80). Despite its massive dimensions, the 170HE uses Green Power to achieve extremely low energy consumption. Furthermore, 170HE is ergonomically designed with the operator’s comfort in mind. The operator can interact intuitively with the machine using the three-dimensional graphical software on a 19” LCD touch screen to program, simulate and optimise the tube bending programs. This machine is also designed to be integrated into the Smart Factory system.
