4400 NC - Rail bending and straightening machine
The horizontal design facilitates simple handling and transport of the rails. With the long cylinder stroke, the rails can be machined upright or horizontally. The tool height of 300 mm allows for straightening and bending of all standard rail profiles. The abutments can be set electro-mechanically to the rail profile required. With the quick-change tool system, the machine can be refitted for a different rail profile very quickly.
A modern, powerful CNC control with laser system supports the operator when bending and straightening the rails. The operator can enter the bending parameters such as the bending radius and the length of the rail numerically. Even bending parabolic curves is supported by the control system. The hydraulic horizontal press then controls the cylinder stroke and the rail feed of the powered roller conveyor in automatic mode.
