Danobat presents the ESTARTA-175 and ESTARTA-250 centerless grinding machines. Aimed at small-batch manufacturing. These are centerless 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 maximum versatility in conjunction with 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 centerless grinders from Danobat has been also included. This design maximizes the regulating spindle stiffness.
