ESTARTA-250 centreless grinding machine DANOBAT

DANOBAT presents the ESTARTA-200 and ESTARTA-250 centreless grinding machines. Aimed at small-batch manufacturing. These are centreless grinding machines with a cantilever wheel head designed to reduce the loss of rigidity typically found on head constructions of this type.

They have 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.

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

Grinding wheel width: up to 250 mm

Grinding wheel peripheral speed: up to 120 m/s
