Expanding mandrel

There are two options for the expanding mandrels: 1. "Inclined plane" system 2. "Umbrella" system The expanding mandrel with the "inclined plane" system has a high tensile strength, but a limited extension range. It is regulated manually or by an actuator. The face chuck is positioned on the left side of the mandrel, and the puncher center point is on the right side. Adjustable stops are positioned at both ends. Due to its improved stable mechanics, the expanding mandrel with the "umbrella" system has a high tensile strength and a clamping range of up to 1,200 mm. Thanks to this feature, the finished product achieves a large width. Dornieden Anlagentechnik GmbH has already supplied more than a hundred expanding mandrels around the world. We are happy to tell you more about our unit!
