In continuous coil processing, stopping the strip to cut it means lost productivity. Tracking shear lines solve this problem by cutting the material while it is moving, synchronized with the line speed. This technology, also known as flying shear or cut-on-the-fly, has become the preferred solution for high-throughput cut-to-length operations.
The tracking shear works by accelerating the shear carriage to match the strip speed during the cutting window. Once synchronized, the shear blade descends and makes the cut without interrupting material flow. Servo-driven tracking systems can make up to 30 cuts per minute while maintaining length accuracy within +/-0.5 mm.
Beyond speed, tracking shear lines offer superior edge quality compared with stop-and-go methods. The continuous, low-impact cutting action produces burr-free edges that often require no secondary deburring. This is a major advantage for processors feeding stamping presses or roll forming lines where edge condition directly affects downstream operations.
For manufacturers planning new coil processing capacity, the tracking shear line represents the state of the art in balancing speed, accuracy and material utilization, making it a cornerstone of modern, high-efficiency processing plants.
