CNC izoblikovalni stroj DENN NTR-130/50

DENN NTR 130-50

The DENN NTR-130/50 CNC spinning machine was manufactured in 2022 in Spain by INDUSTRIAS PUIGJANER S.A. This machine is used for plastic forming of components made from a broad range of materials such as brass, silver, iron, and stainless steel. The forming process exclusively utilizes the plastic properties of metals, eliminating the need for cutting tools.

The automatic DENN spinning machine enables both metal spinning and flow forming operations. Both processes use precision rollers to shape the workpiece by applying pressure to a high-speed rotating part. Flow forming differs by forming the workpiece through individual roller passes along the mandrel, allowing for components with consistent wall thickness and a more homogeneous surface finish.

The machine’s robust frame houses all essential components with top technical specifications, including a heavy-duty and reliable bed, a hydraulic tailstock, and a headstock with an integrated part ejector. State-of-the-art control elements ensure comprehensive operator-machine interaction.

The NTR 130/50 spinning machine is offered with extensive equipment, including CAD/CAM software, an additional support roller, and trimming tools. Throughout its use, the machine has only clocked 1,323 operating hours. The total weight of the machine is approximately 9,000 kg.
