9 axis spring coiling machine JTC 920

JTC920 9-Axis Spring Coiling Machine

The JTC920 is a 9-axis spring coiling machine designed for high-speed production of springs made from medium-diameter wire ranging from 0.5 mm to 2.0 mm. The 9 CNC-controlled axes greatly simplify machine setup and changeover. Adjustment and control of the coiling points responsible for the spring's outer diameter are achieved via individual motors rather than a cam-and-crank mechanism. Additional features include a horizontally retractable winding unit, CNC-controlled extension of the central mandrel, and vertical movement of the mandrel.

Types of Springs That Can Be Produced:

• Compression springs: conical, cylindrical, barrel-shaped
• Gland (stuffing box) springs
• Simple torsion springs
• Extension springs with hooks formed from full coils (<60°)

Standard Equipment Includes:

• Wire feeding unit with 200 kg load capacity
• Electromagnetic length sensor with ±0.005 mm accuracy and automatic sorting function

Optional Equipment:

• Industrial camera for precision and geometry inspection with automatic sorting
• Tooling set for producing basic torsion springs
