Long-Term Accuracy. Built for 24/7 Productivity.

To ensure consistently precise grinding performance, the G1 Series is built on a support bed engineered for strength and stability. Utilizing advanced structural analysis, the bed has been carefully designed to deliver exceptional rigidity while minimizing deflection under heavy loads. This robust foundation actively suppresses unwanted vibration during grinding operations, protecting accuracy and surface finish over extended production runs.

By combining durability with vibration control, the support bed provides a stable platform that not only enhances machining precision but also extends the lifespan of both the machine and tooling—delivering lasting value and reliability for manufacturers.


High Rotational Accuracy and Feed Accuracy

STAT BEARING® sets a new standard in spindle technology by combining hydrostatic and hydrodynamic principles into a single, hybrid design. This innovative approach completely eliminates metal-to-metal contact within the bearing, drastically reducing friction, heat generation, and wear.

The result is a spindle system that maintains peak performance and precision over significantly longer service life compared to conventional spindle bearings. With its ability to support heavy loads, absorb vibration, and deliver ultra-smooth rotation, the STAT BEARING® ensures your grinder operates with unmatched accuracy, reliability, and stability—even in the most demanding production environments.
