The GL4i-150 SWITCH is a high-accuracy, versatile Universal OD Grinding Machine from JTEKT Toyoda, built for production environments requiring long-term precision for external diameter (OD) and face grinding applications. It is described as an economical, triple-duty cylindrical grinding machine.

The GL4i-150 SWITCH is designed for flexibility, featuring a manually adjustable wheelhead that can be set to Plain Head (0 degrees), 30-degree, or 45-degree angle positions. The 45-degree swivel capability is a key element of the Switch series, which allows for increased thrust on the wheel during face grinding. This results in both faster cycle times and a reduced probability of burning the workpiece face.

This model is engineered to accommodate longer workpieces while delivering superior grinding accuracy. Its core specifications include:

• Distance Between Centers: 59.0 inches (1,500 mm), providing an extended capacity.
• Swing Over Table: 12.6 inches (320 mm).
• Grinding Diameter (Max): 11.8 inches (300 mm).
• Wheel Surface Speed: High-speed operation at 8,500 SFPM (45 m/s) for efficient, high-quality material processing.

The GL4i-150 SWITCH is a robust and reliable solution for general-purpose precision cylindrical grinding, capable of handling medium-to-long workpieces with exceptional accuracy.
