TG-12×4 Hi-Accuracy System with CNC Dressing and Robotic Loading
The Royal Master TG-12×4 Hi-Accuracy systems have ground thousands of geometries for companies worldwide. At IMTS, our TG-12×4 features CNC dressing, Fanuc robotic loading, and an innovative pallet loading system for raw material. After grinding, the part will be unloaded, cleaned, gauged, and palletized. The gauge will measure all five part diameters and provide feedback to the machine’s control. The onboard analytical suite will graph the part diameters, offering real-time insights into the production run.
- Capability of grinding to under .00001” (.00025 mm) - Straight and Round
- 12” Diameter x 4” Wide Grinding wheel
- 3-Axis CNC dressing on grinding wheel
- Ram and Regulating Wheel Axis for 7 Total Axis
- Available in a TG-12x4 or TG-12x8 for grinding multiples of parts simultaneously
Royal Master Grinder’s High Accuracy system lives up to its name with a 7-axis CNC machine designed for tight tolerance applications. It grinds a five-diameter part, while also handling cleaning, gauging, and repalletizing. The machine charts data on-screen and stores it in an onboard database for future reference.
The machine in our booth features a 12” diameter, 4” wide grinding wheel with variable speed, automatically adjusting RPM to maintain surface footage as the wheel wears. This ensures consistent cycle times even as the wheel size decreases and allows for the use of super-abrasives on exotic materials.
Mounted on a Starrett surface plate, lapped to .0002” across the entire granite surface, the machine achieves precision grinding to under .00001” in roundness and straightness. It features a high-accuracy Ram Bed position control with frictionless cross roller, ball screw, and servo motor movement, with a glass scale providing one-tenth micron resolution. The HMI is a 24″ touchscreen for all machine functions.
The intuitive new machine control system simplifies daily interactions, with easy navigation and programming for CNC dressers through onboard wizards or G-code. Wheel spindles use class 7 ABEC angular contact ball bearings for long life and superior control.
A FANUC Robot handles part loading and unloading from multiple vertical pallets within a secure, enclosed system. The enclosure includes safety interlocks, air mist filtration, and effective coolant containment. The robot automatically processes two parts at a time, ensuring fast and efficient cycle times.
Keyence provides a post-process part measurement gauge with rapid scan capabilities for automatic compensation, while Schmitt Industries offers an SBS Dynamic Wheel Balancer with acoustic emissions for optimal vibration control, eliminating the need for non-contact dressing and grinding movements.
