The GE6i-400 is the longest-capacity model in JTEKT Toyoda’s GE6i series, functioning as a high-accuracy Outer Diameter (OD) Cylindrical Grinding Machine. It is engineered to perform precision grinding on extremely long and large workpieces, providing the necessary structural integrity for long-term machining accuracy in demanding job shop and high-production environments.

This machine is built for maximum stability and geometric accuracy. The structure features a single Meehanite casting for superior thermal stability and rigidity over its extended length. Precision is ensured through hand-scraped precision surfaces and an advanced hydrostatic wheelhead bearing and way system. The machine also utilizes the patented TOYODA STAT BEARING and floating plate technology to maintain high accuracy and precise positioning across the full travel distance. The GE6i-400 is configured with a dedicated plain or angle grinding head.

The GE6i-400 offers the maximum length capacity in this series. Its key specifications are:

• Distance Between Centers: 157.4 inches (4,000 mm), accommodating 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 optional capability for high-speed grinding at 8,500 SFPM (43 m/s).

The GE6i-400 is essential for manufacturers specializing in the ultra-precise finishing of massive, lengthy cylindrical components.
