The GL7 is a cylindrical grinding machine for dedicated processes in a high-production environment. It features a hydrostatic wheelhead bearing and way system, and the patented TOYODA STAT® BEARING and floating plate to ensure high accuracy and positioning. This machine is offered in plain- and angled-head configurations.

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.
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.×
With a high surface speed, the optional CBN wheel maximizes grinding efficiency.×
Designed for dedicated part production, the GL Series offers a wide range of options for production grinding.×
