SF-1A Wire Coiling Machine

An ultra-thin wire coiling machine that can process wires thinner than 20 µm. 

The SF-1A enables a feed roller diameter of 16 mm and an ultimate wire guide length of 6 mm to further expand the processing range of ultra-thin wire springs.

Dedicated MNO Program for Spring Production

  • Easy operations for quicker preparation.
  • High resolution for controlling the latest servo motors.
  • Allows varied control based on measurement results, such as the pitch, diameter, and bend angle.
  • Common program for both torsion machines and coiling machines.
  • Includes a motor sensor system.
  • Versatile production management screen and production data collection function.

Coiling Mechanism

  • A specialist design for ultra-thin wires, with a feed roller diameter of 16 mm and a wire guide length of 6 mm.
  • The cut tool and coiling point areas have been strengthened to provide both stability and adjustability.
  • Tools are attached using a standard mechanism for attaching wire guides with reference to the feed roller, and the newly developed pitch arbor unit can be moved up, down, left, and right to adjust the arbor position in relation to the wire guide.

Optional Equipment

  • Initial tension servo unit
  • Core forward/reverse servo unit
