The TG4-63 is a highly versatile and programmable Universal Grinding Machine from JTEKT Toyoda, featuring a twin-wheel modular configuration. This machine is designed to deliver exceptional, long-term machining accuracy in high-production environments.

The TG4 series offers high flexibility due to its automatic wheelhead indexing, which allows for multiple grinding configurations and simplifies changeovers for diverse part processing, including both Outer Diameter (OD) and Inner Diameter (ID) applications. Like all JTEKT precision grinders, the TG4-63 incorporates the patented TOYODA STAT BEARING to ensure superior stability, rigidity, and high precision over the machine’s life.

This model is a medium-capacity machine offering extended length for parts compared to the TG4-32. Its key specifications are:

• Distance Between Centers: 24.8 inches (630 mm), providing ample length for mid-sized components.
• Swing Over Table: 12.6 inches (320 mm).
• Maximum Grinding Diameter: 8.6 inches (220 mm) for Outer Diameter (OD) and 4.7 inches (120 mm) for Inner Diameter (ID).
• Wheel Surface Speed: Capable of high-speed grinding at 8,850 SFPM (45 m/s).
• Weight Capacity: 330 pounds.

The TG4-63 is a powerful, flexible, and accurate cylindrical grinder that is ideal for high-speed, high-production shops processing a range of parts.
