Rings, discs, and other radially-symmetric parts scan most efficiently when the part rotates past a fixed scan head rather than the head tracing the part's circumference. SDI's turntable systems are seven-axis static gantry platforms — a lower-cost alternative to full 3D scanning for components with curvature confined to a single plane, such as engine nacelles.
Two sizes cover the range, from mid-scale rings to the largest circular airframe components.
Turntable Through-Transmission System
A precision rotational platform for ring, disc, and cylindrical components, with multiple scan heads positioned around the turntable for full circumferential coverage in a single rotation.
| Configuration | Rotational turntable |
| Delivery | Through-transmission |
| Typical use | Rings, discs, cylindrical aerospace/automotive components |
Large Turntable Through-Transmission Ultrasonic System
A seven-axis high-performance static gantry system designed specifically for large circular airframe components such as engine nacelles. The seven-axis design (Y1, Y2, Z1, Z2, B1, B2, T) provides a lower-cost system for components with curvature confined to a single plane. A large turntable is fully integrated into the programmable motion sequence.
The system switches between English and metric units, and can be extended with additional axis motion for non-circular parts. For full 3D scanning needs, SDI's 5380 and 5420 series gantry systems are available.
| Configuration | 7-axis static gantry, integrated turntable |
| Turntable rotation | 360°, 10 rpm |
| Y-axis range | 6–10 ft, 16 in/sec |
| Z-axis range | 6–10 ft, 6 in/sec |
| Accuracy | ±0.010 in. |
| Units | English or Metric, switchable |
| Typical use | Large circular airframe components, engine nacelles |
