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.


  • The SF-1A is the result of our mission to achieve the smallest coiling in the world.

    Oriimec’s world-renowned ultra-thin wire machines have now evolved further.

    -Ultra-thin wire coiling machine for wire diameters of 0.016 to 0.1 mm

    -Enables a feed roller diameter of 16 mm and an ultimate wire guide length of 6 mm

    -Equipped with 4 standard axes: feed, cut, pitch, and coil diameter.

    -An optional initial tension servo and arbor front-back servo can be added.

    -Uses a mechanism designed to assist ultra-fine adjustment.

    -Equipped with a standard ultra-high accuracy sensor (MSD) to achieve the accuracy required for ultra-thin wires.

  • 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.

  • MSD gauge to achieve the accuracy required for ultra-thin wires

    Ultra-thin wires require an extremely accurate gauge.
    The SF-1A achieves this with the MSD gauge.

    -Included in the SF-1 as a standard feature, the MSD is a high-accuracy sensor that uses a servo motor.

    -The numerical values in the program are corrected with a high degree of accuracy based on the measurement results.

  • Dedicated MNO2 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.

  • Optional Equipment

    -Initial tension servo unit

    -Core forward/reverse servo unit
