Material: aluminum alloy
Compared to the otherwise common adapter flanges made of low-cost cast iron (GG), we have switched production to a high-quality aluminum alloy for the following reasons:
Fits can be made better and more accurately in aluminum than in cast iron. Due to the lamellar graphite in gray cast iron and the resulting micro-depressions on the surface, parts made of GG are not as production stable as parts made of aluminum.
The aluminum flange is almost 50% lighter. Due to the already large 100 mm jaw chuck and the additional flange required, this has a positive effect on the torque and also on the wear. Especially the drive belt is no longer so heavily loaded when running up the machine than with a heavy steel or GG flange.
