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.
Our grinding machines use Toyoda’s own conversational controls. In a convenient touchscreen panel, operators are able to program at the machine.
Designed for dedicated part production, the GL4-i offers a wide range of options for production grinding.×
Solid Bed Construction
Toyoda grinding machines are made of stress-relieved cast iron that utilizes FEM design for optimum thermal stability and vibration dampening.×
Automatic Wheelhead Retraction
In the event of power failure, the grinding wheel automatically retracts from the workpiece. This protects the grinding wheel from damage.×
