Super-strong mandrel

With all the advantages of a hexagonal clamping mechanism, the segmented clamping bushing has an internal hexagon shape that fits onto the clamping pyramid and enables maximum cutting performance. The lubrication and consistent clamping forces ensure constant production flow for maximum reliability and machine utilisation.

The company says that due to the hexagonal pyramid clamp, maximum torque transmission can be achieved. In comparison to the Hainbuch Mando T211 mandrel, the new addition generates up to 155% more transmissible torque and up to 57% higher stiffness. This makes it possible to achieve higher machining parameters and consequently improve the yield of finished parts.

Greater process reliability is facilitated by the spacious layout between the clamping bush and the clamping pyramid. Even during the clamping process, this design prevents virtually any dirt or contaminants getting onto the surfaces. This significantly reduces the frequency of maintenance tasks such as cleaning and lubrication and the subsequent time required for such non-productive activities. 

Overall, the Maxxos T211 mandrel has a clamping diameter range of 18 to 100mm and the clamping areas of each size are designed to overlap. The advantage of this configuration gives users that ability to choose from up to three mandrel sizes depending on the clamping diameter. With the Maxxos, the larger the mandrel; the greater its stability and rigidity. The aligned, segmented clamping bushings have a minimum concentricity of 0.01mm and can even be supplied in a high precision version.
