WH-16 – Wire Diameter 0.5 to 1.6 mm, 2 Point Coiling

Japan Spring Machines

A 7-axis, 2-point coiling machine with a maximum wire diameter of 1.6 mm and excellent cost-effectiveness.
Equipped with a freely oscillating rotary cut as a standard feature for high-speed production and high accuracy in a reduced preparation time.


Feature 1

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 2

Newly-developed rotation point servo
  • Our new WH-16 point unit includes a rotating servo.
  • Select the adjustment method of your choice (1st pin or 2nd pin can be selected).
  • You can also select a different servo for both the 1st pin and 2nd pin and use them in conjunction.

Feature 3

5-point coiling machine with a wire diameter of 0.5 to 1.6 mm
  • Enables easy setup and high-accuracy, high-speed production of springs.
  • The clockwise/counterclockwise direction can be switched simply by configuring a setting in the program.
  • An optional rotation point servo and initial tension servo can be added to the coiling point.
  • The alignment of the cut tool and core does not require readjustment after being decided once.
  • One-touch switching between oscillating cut and straight cut.
  • The oscillating cut bearing (oscillation) can be freely adjusted.
  • An optional slip sensor is provided for detecting slips when feeding.
  • Includes our newly-developed specialist MNO program for spring production, enabling simple and precise operations.

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

Feature 5

Optional Equipment
  • Initial tension servo (tilting operations)
  • Rotation point servo (rotation operations)
  • IS-1 shape detection unit with camera
  • Slip sensor to detect wire slips
