TG4-63 Universal Grinding Machine

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.
