The PRIMO TG-MILL from Innerspec (Forest, VA) is an integrated ultrasonic thickness measurement system designed for automated inspection of non-ferromagnetic metallic components directly within a CNC machining environment. Using Electromagnetic Acoustic Transducer (EMAT) technology, the system performs non-contact, couplant-free thickness measurements from a single side of the component on materials including aluminum, titanium, copper, and other compatible non-ferromagnetic metals.
The system is purpose-built for CNC integration through standard toolholder and spindle interfaces, including BT30, BT40, HSK63A, HSK100A, and HSK-125A configurations. This allows thickness measurement to become part of the automated machining process. Measurement data is transmitted wirelessly to a base station that communicates with the CNC controller, supporting automated inspection, thickness verification, and process control without removing the component from the machine.
Because EMAT does not require physical contact or liquid couplant, measurements can be performed directly on machined surfaces without cleaning the part or interrupting the manufacturing process. The system is designed specifically for the CNC environment and is unaffected by cutting fluids, coolant, machining debris, or metallic dust on the component surface.
PRIMO TG-MILL provides single-sided thickness measurement accuracy of ±5 µm (±0.0002 in.) or better over a thickness range of 0.5 to 100 mm (0.020 to 4.0 in.). It supports both shear and longitudinal EMAT sensors, with sensor options for spot checking and scanning.
The battery-powered instrument provides approximately eight hours of continuous operation with wireless data transmission. A dedicated charging cradle provides a secure docking and charging location when the instrument is not installed in the CNC machine, helping keep the system powered and ready for operation.
