Hainbuch Maxxos T211: the hexagonal, super-strong mandrel

A mandrel with hexagonal pyramid shape instead of a round taper, designed with stringent
manufacturing requirements and process reliability in mind. Hainbuch has acted in response to
demand from specific areas that have been growing year by year. Users are requesting
mandrels that deliver higher performance as well as process reliability. The result is called
Maxxos. It exceeds even the specified customer requirements and more than this, offers all
the advantages of a hexagonal clamping mechanism. The segmented clamping bushing with
hexagon inside shape fits perfectly onto the clamping pyramid and enables maximum cutting
performance. The lubrication, combined with its tightness ensures a very constant production
flow and as a result, achieves maximum reliability. Customers that value process reliability and
maximum torque transmission will be delighted with the Maxxos T211.

The best for heavy I.D. clamping
Thanks to the hexagonal pyramid clamp, maximum torque transmission can be achieved. Up
to 155 percent more transmissible torque and up to 57 percent, higher bending stiffness
compared to the classic Mando T211 mandrel. This makes it possible to achieve higher
process parameters and consequently improve the yield of finished parts. Greater process
reliability is facilitated by the spacious layout between the clamping bushing and the clamping
pyramid. Even during the clamping process, this design prevents virtually any dirt getting onto
the surfaces. This significantly cuts down the frequency of maintenance times for cleaning and
lubrication. Overall, the mandrel has a clamping diameter range of 18 to 100 mm. The
clamping areas of each size are designed to overlap. This has the advantage that users can
choose from up to three mandrel sizes depending on the clamping diameter. The larger the
mandrel is, the greater its stability and rigidity. Smaller mandrels may be able to handle more
of the customers smaller workpieces. Users are free to choose the size they want, based on
their own judgment and preferences. The aligned, segmented clamping bushings have a
minimum concentricity of 0.01 mm and can even be supplied in a high precision version.
