THE DAILY GRIND FOR YEARS TO COME – The TOYODA STAT® BEARING uses a hybrid of hydrostatic and hydrodynamic technology to eliminate metal-to-metal contact inside the bearing. This allows your grinder to run at top performance longer than your typical spindle bearing.

ACCURATE BY DESIGN – Toyoda’s floating plate absorbs movement in the ballscrew to maintain grinding accuracy and positioning.

USER-FRIENDLY HMI – Our grinding machines use Toyoda’s own conversational controls. In a convenient touchscreen panel, operators are able to program at the machine.
