What is a CNC Spring Machine?
A CNC spring machine is a computer-controlled wire forming machine that automatically coils, bends, and shapes metal wire into springs using servo-driven axes. Unlike manual spring winders, CNC spring machines achieve ±0.01mm positioning accuracy across 2 to 14 axes, enabling mass production of compression springs, extension springs, torsion springs, and custom geometries at speeds up to 110m/min.
Dongzheng Spring Machine has manufactured CNC spring machines since 2004, with 150+ machines operating globally in Vietnam (40+ units), Brazil (10+ units), South Korea, and Indonesia.
