HAINBUCH has expanded its MAXXOS family of mandrels with the MAXXOS T-212, a next-generation ID clamping solution.
At the center of the MAXXOS design is a hexagonal pyramid clamping interface that replaces the traditional round mandrel connection between the mandrel body and the segmented clamping bushing. Instead of relying on friction alone, the hexagonal geometry creates a positive mechanical fit that increases torque transmission and resistance to vibration. The result is a mandrel that holds parts with stability, even during aggressive machining operations, the company reported.
"Compared to conventional round mandrels, the MAXXOS system delivers up to 155% greater transmissible torque and up to 57% higher rigidity," said a company spokesperson. "This added stability allows shops to increase feedrates, take heavier cuts, and maintain consistent part quality while extending tool life."
The hexagonal pyramid design distributes forces across six contact surfaces rather than relying on a single round interface. This creates a rigid connection between the clamping bushing and the mandrel body, reducing micro-movement and improving damping during machining.
"In practical terms, the MAXXOS T-212 behaves less like a traditional mandrel and more like a structural extension of the spindle, giving manufacturers the confidence to push machining parameters further while maintaining process reliability," said the spokesperson.
The MAXXOS T-212 also features a draw-bolt-free design, making it suited for components with blind bores or minimal clamping lengths. Because no draw bolt extends into the workpiece, the full clamping length of the mandrel can be utilized, providing greater flexibility for challenging part geometries.
An integrated pull-back effect helps ensure the workpiece is securely positioned against the end stop, improving axial stability and supporting repeatable precision during complex machining operations.
"Despite its focus on rigidity and torque transmission, the MAXXOS system maintains the high precision expected from HAINBUCH workholding solutions," said the spokesperson. "The mandrel offers runout accuracy of ,â0.01 mm as standard, with ultra-precision options available down to ,â0.002 mm. Combined with HAINBUCH,Äôs segmented clamping bushings, the MAXXOS T-212 delivers a powerful combination of precision, rigidity, and vibration damping, enabling manufacturers to achieve both high performance and consistent part quality."
The spokesperson added: "The MAXXOS T-212 is designed for shops that need more than traditional ID clamping can provide. By combining the structural strength of hexagonal geometry with HAINBUCH,Äôs advanced clamping technology, the system delivers the stability required for modern high-performance machining."
