Spring Forming Tool uses piezo-based technology.

October 26, 2004

Computer-controlled, Spring Forming Tool adjusts for wear in real-time and compensates for material inconsistencies. After feed rollers push spring wire out through quill, coiling tool bends wire to create helical shape. Tight tolerances are kept by using LVDT to measure diameter of coil as it is being formed and electronically adjusting tool distance from quill 400 times/sec. Embedded piezo-electric device causes tool to grow longer or shorter by as much as 0.004 in. Read More
