The SH-3A, a multifunctional coiling machine with 1-point coiling, torsion attachment, and an initial tension servo, has further evolved. This coiling machine can now process an even greater range of torsion springs.


  • 1-point coiling with a wire diameter of 0.08 to 0.3 mm

    -Equipped with 8 standard axes: feed, cut, pitch, point, torsion, initial tension, coil front-back, and MSD.

    -Easier setup and greater speed than previous models, as the cut axis and torsion axis are separated.

    -Suitable for high-speed production of ballpoint pen springs, torsion springs, and elliptical springs in addition to standard cylindrical springs.

    -Optional ultra-thin wire attachment can be used to coil springs with a diameter of 0.08 mm or less.

  • 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.

  • 3 types of wire guides

    The SH-3A has 3 wire guides with different lengths:

    -Short guide with a guide length of 23 mm
    Provides greater accuracy for short springs due to its shorter guide length, while retaining the same clearance length as a standard wire guide.

    -Standard wire guide with a guide length of 30 mm
    Enables use of all tools available for the previous SH-3,SH-3Ⅱ wire guide.

    -Wire guide for ultra-thin wires with a guide length of 16 mm
    Enables coiling of wires with a diameter of 0.08 mm or less.

  • 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

    -Ultra-thin wire attachment

    -3-dimensional bending servo unit to improve stability and speed when creating antenna springs

    -Capacitance level sensor

    IS-1 shape detection unit with camera
