Description

7-Axis Spring Coiling Machine – Model JTC 720

The JTC 720 is a 7-axis CNC spring coiling machine designed for high-speed production of springs made from medium wire with diameters ranging from 0.5 mm to 2.0 mm. The 7 CNC-controlled axes significantly simplify setup and changeover, especially when compared to traditional 2- or 3-axis machines.


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
