SH-3Ⅱ- Wire Diameter 0.08 to 0.3 mm, 1-Point Coiling

Japan Spring Machines

The SH-3, 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.


Feature 1

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-1.
  • 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.

Feature 2

Dedicated MNO 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.

Feature 3

3 types of wire guides

The SH-3II 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 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.

Feature 4

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.

Feature 5

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
