The GL4i-50 SWITCH is a high-performance model within JTEKT TOYODA’s Universal OD Grinder lineup, setting the standard for applications demanding long-term machining accuracy and high-production capability. As part of the GL4i SWITCH series, this machine stands out as an economical triple-duty cylindrical grinding machine. Its key feature is the manually adjustable wheelhead, which allows for swiveling up to 45º (as well as 0º and 30º positions), making it exceptionally versatile for grinding both straight and angular surfaces. This 45º swivel capability is a significant advantage, providing more thrust on the wheel diameter during critical face grinding operations. The result is a combination of faster cycle times and a reduced probability of burning the workpiece surface during face grinds.

With a robust design, the GL4i-50 SWITCH maintains JTEKT TOYODA’s reputation for long-term reliability and accuracy. The machine has a generous Swing Over Table of 12.6 inches (320 mm) and a Distance Between Centers of 19.69 inches (500 mm), accommodating a wide range of parts with a maximum grinding diameter of 11.8 inches (300 mm). It supports a maximum workpiece weight of 330 lbs and operates with a high Wheel Surface Speed of 8,500 SFPM (45 m/s), ensuring efficient material removal and superior surface finish for ferrous, non-ferrous, and high-temperature alloy grinding applications.
