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.

High rigidity, low vibration bed

To achieve high-accuracy grinding over a prolonged period, the support bed has been designed and analyzed to provide sufficient rigidity and to suppress unnecessary vibration during grinding.

Long Spindle Life

The patented TOYODA STAT® BEARING uses hydrostatic technology to eliminate metal-to-metal contact between the wheel spindle and the bearing. This exclusive technology allows for many years of trouble-free precision performance.
