CENTERLESS CYLINDRICAL GRINDING MACHINES
ESTARTA-250 CENTERLESS GRINDER


DANOBAT presents the ESTARTA-250, the solution for reduced batch sizes. The ESTARTA-250 is a cantilever centerless cylindrical grinder that minimizes inherent stiffness losses of this construction.

ESTARTA-250 is the new centerless grinding machine with a cantilever design that minimizes inherent stiffness losses of this construction. It has been specially developed to achieve the maximum versatility in conjunction to the maximum productivity. Cantilever configuration will offer the required flexibility to those customers sensitive to today’s fast change over requirements. The machine is also prepared to grind at high speed (120 m/s with CBN technology) paying special attention to rigidity and vibration damping.

In the aim of achieving the best dynamic performance, the revolutionary wheelhead design of the new centerless grinders generation from DANOBAT has been also included. This design maximizes the regulating spindle stiffness.
