What Is a Camless CNC Spring Forming Machine?

A camless spring machine is CNC-controlled equipment for making many spring types—extension, compression, torsion and more. Versus traditional cam spring machines, camless CNC systems handle multiple spring styles with simpler operation, higher efficiency and better accuracy. The forming principle: metal wire is fed by the feed axis between the bend and rotate axes; the CNC then drives those axes so the wire bends into the required spring shape.

CNC control delivers high-precision machining and stable spring quality. The machine can form many shapes and sizes—arcs, trapezoids, rectangles and more—to meet different customer needs. Operation is simple: enter machining parameters for automated production that raises throughput and accuracy, with convenient maintenance and lower service cost.

Camless spring machines are widely used in metalworking—automotive parts, electronic components, general machinery and more. As technology advances they are becoming more common and are set to be mainstream equipment in spring and wire forming.
