The BZ 70 H gear grinding machine is another innovation of Burri. The machine is designed for very small planet gears and sun gears. Due to the mini grinding worm, very short clamping equipment can be used. The horizontal design allows very fine adjustment of the tailstock center. Two synchronous workpiece spindles eliminate the unstable rotating tailstock centers and guarantee a very effective workpiece driving. The BZ 70 H is the first non-hydraulic gear grinding machine and therefore also the most energy-efficient on the market.
