TG-12×4 Servo Cycle

The TG-12×4 Servo Cycle machine is capable of Infeed as well as thrufeed grinding from .002” up to 1.5” in diameter. With its large and versatile two panel touchscreen, daily interaction with the machine is intuitive and powerful. Automation from a very basic operator assist device to robotics and post process gauging allows the system to be fully autonomous. 

This is the Royal Master Grinders Model TG-12x4 with our Servo Cycle Ram Bed system. At IMTS 2024 this machine will be infeed grinding a small gearbox part with two bearing journals. It is equipped with an automatic grinding wheel dresser and automatic part ejector.

The Servo Cycle machine has the same robust spindles and over the wheel servo controlled dressers as the other machines in the TG-12×4 line. The Ram Bed Position Control is what makes it unique. The large, two-panel, intuitive touchscreen controls make operators more productive. The Ball Screw and Servo Motor provide accurate infeed grind cycle movement and position control for both infeed and thrufeed grinding.

The machine’s controls are Windows-based, enabling remote access for data reporting, connection for remote troubleshooting, and seamless integration with automation interfaces. Additionally, it can be paired with post-process gauging for data feedback and collection. If your facility already utilizes a Data Management System, Royal Master can seamlessly integrate our machine with your existing system.

The Servo cycle machine offers flexibility with options for either a cast iron or granite machine bed and machine enclosure
