The Burri Model BZ 130 is the first complete gear grinding machine internally-developed by Burri and sets new standards in generating grinding. The patented axes configuration stands out from contemporary design philosophies and allows for a very compact design. The complete space requirement is only 4.2 square meters (45 square feet).
The BZ 130 features world-class features including:
-Bias / Twist Control.
-Asymmetrical Gears.
-Line Dressing.
-Single Flank Dressing.
-Constant Surface Speed Sensing.
-Large wheel width facilitates segmented grinding worms for roughing, finishing & polishing.
-Grinding wheels are mounted directing on the spindle without flanges - no crane required.
-Unbeatable energy efficiency - 10 kVA in production with loading systems!
Designed from the start as a double spindle machine with a chip-to-chip time of 2 seconds and an integrated loading system this machine is optimally designed for high production.
For workpiece storage, Burri offers basket cells, conveyor belts as well as more customized solutions dependent upon your requirements. Existing or customized gear storage can also be integrated.
Rebuilding & improving existing generating grinding machines is in Burri's DNA since 2002. Along the way, NEW machines were developed (such as the BZ 130!) along with rebuilds. Now there are more than 100 Burri machines sold and in operation throughout the world. Even mother machine builders use Burri for the more 'difficult' applications...
