A 5-axis, 2-point coiling machine with a maximum wire diameter of 0.8 mm and excellent cost-effectiveness.

The simple structure enables high-speed production and high accuracy in a reduced preparation time.


  • 2-point coiling machine with a wire diameter of 0.2 to 0.8 mm

    -Maximum outer coil diameter of 28 mm

    -Equipped with 5 standard axes: feed, cut, wedge pitch, push pitch, and outside coil diameter.

    -An optional initial tension servo can be added.

    -Enables easy setup and high-speed production at a low cost.

    -Includes our newly-developed specialist MNO2 program for spring production, enabling simple and precise operations.

    -Features Oriimec’s world-renowned precision processing technology for ultra-thin wires.
    The WH-8A also includes cutting-edge computer control technology.

  • Parts for 2-point mechanism

    -All fine-adjustment mechanisms have scale marks to improve reproducibility and ease of fine adjustment.

    -Cut operations use a crank mechanism to achieve high-speed production.

    -Coiling pin adjustment features an oscillating mechanism.

  • Dedicated MNO2 Program for Spring Production

    -Easy operations for quicker preparation.

    -High resolution for controlling the latest servo motors.

    -Compatible with compression spring creation programs based on line graphs.

    -Allows varied control based on measurement results, such as the pitch and diameter.

    -Common program for both torsion machines and coiling machines.

    -Includes a motor sensor system.

    -Versatile production management screen and production data collection function.

  • Taper synchronization constant

    Enables the taper tilt to be managed with a value from 0 to 100.
    Suitable for load adjustment in addition to shape adjustment, as fine adjustment can be performed in 100 levels.

  • Optional Equipment

    -Initial tension servo unit

    -Counterclockwise unit

    -Slip sensor to detect slips in wire feeding

    -MSD sensor with servo motor to enable measurement of free length and outer diameter.

    IS-1 shape detection unit with camera
