The GE6i-320 is an exceptionally long and high-precision Outer Diameter (OD) Cylindrical Grinding Machine from JTEKT Toyoda’s GE6i series. It is specifically built to handle the grinding of very long, large workpieces while ensuring the long-term machining accuracy demanded by both high-production and precision job shop environments.

Built on a foundation of a single Meehanite casting for ultimate rigidity and thermal stability, the GE6i-320 is engineered for uncompromising precision. It features hand-scraped precision surfaces and a sophisticated hydrostatic wheelhead bearing and way system. This stability, combined with the patented TOYODA STAT BEARING and floating plate, guarantees high accuracy, superior dampening, and precise positioning over extreme lengths. The machine is available with a dedicated plain or angle head configuration.

The GE6i-320 is one of the largest capacity models in the GE6i line. Its key specifications are:

• Distance Between Centers: 125.9 inches (3,200 mm), offering massive length capacity for the longest cylindrical parts.
• Swing Over Table: 22.0 inches (560 mm).
• Maximum Grinding Diameter: 21.6 inches (550 mm).
• Weight Capacity: 1,100 pounds.
• Wheel Surface Speed: 6,500 SFPM (30 m/s) standard, with an available option for high-speed grinding at 8,500 SFPM (43 m/s).

The GE6i-320 is the ideal machine for manufacturers needing to achieve high-accuracy geometry and surface finish on extra-long cylindrical components.
