The high production capacity and the quality standard meet the most demanding market requirements as the RGB is the result of research focused on the production of engine valves.
The granite base guarantees advantages in terms of both dimensional stability as well as damping of vibrations and reduced reduced coefficient of thermal expansion.
Gravity loader with cylinder and pneumatic gripper for valve support on blade (positive load).
The grinding wheel is operated by a hydrodynamic spindle at a speed of 45 mt./s.
The vibration level is reduced to a minimum as there is no mechanical transmission.
The unit is equipped with an automatic dynamic balancer.
The dressing of the grinding wheel is CNC-controlled via an 8000 rpm electrospindle.
The driving wheel spindle is mounted on a double support with high-precision roller bearings and is rotated by a brushless motor.
