MAPAL chucks give the best of both worlds

The HTC (High Torque Chuck) range of chucks from MAPAL enables machine tool users to benefit from the fast, convenient and safe tool changes offered by hydraulic chucks in applications where it would previously have been necessary to use alternative clamping technologies.

The chucks combine rigidity with a high radial run-out accuracy of 3 µm or better. Bending resistance is typically 1.4 times that of comparable shrink chucks, and torque transmission capacity is up to 20 per cent greater. These features ensure an optimum finish to the workpiece, while also protecting the machine spindle, guarding against chipping of the tool cutting edge and enhancing tool life. All MAPAL HTC chucks offer axial adjustment. They are currently available in HSK63A and SK40 mountings with clamping diameters from 6 mm to 32 mm, and will also, in the near future, be available with other spindle configurations. Until now there were many tooling applications where conventional hydraulic chucks could not be used because of their limited torque transmission capacity and their unsuitability for handling high levels of radial thrust. In these applications, it has been necessary to adopt other clamping technologies, often at the expense of convenience and ease of use. MAPAL's HTC hydraulic chucks provide an effective solution to these problems. A solution particularly well suited for use in milling and precision drilling operations, as well as for rough machining, heavy duty metal cutting and other similarly demanding applications.
