WH-26A

8-AXIS CNC DUAL-POINT COILING MACHINE
For wire diameters of ø0.6 ~ ø2.6 mm

WH-26A achieves high-speed production, high-precision coiling,and reduction of setup time.
It can process outer coil diameters up to ø70 mm.
The coil program, equipped with a pitch diagram,allows the user to easily create programs for multiple shapes.

8-AXIS CNC DUAL-POINT COILING MACHINE

WH-26AFeatures
8-axis control with an emphasis on operability andquality improvement, due to the introduction of a dual
feed roller- The WH-26A supports various shapes with the standard featuresof 8-axis control: cut, wedge-pitch, push-pitch, point, auxiliary
point, center-cam, and arbor front and arbor back.
- The rotary or straight cuts and the wedge-pitch can be switchedby simply moving the eccentric pin.
- You can switch programming between right- and left-hand coilingwithout replacing the heavy slide.
- The WH-26A is equipped with cut, wedge-pitch, and arbor
functions on the center slide. As a result, it only needs toadjust the alignment of the cut tool once regardless of the coildiameter.
- The introduction of the dual feed roller reduces the load of feed
pressure applied to the wire.

Support for IOT

The operating status of machine can be monitored through mobilephones or computers, and regular maintenance with preventive
maintenance functions can contribute to improved production
efficiency.

Optional equipment

A slip sensor that detects the slip of the wire during coiling can beselected as an option.

2 point area for coiling

The center axis moves the point slide vertically and horizontally.
The center slide is driven by a gear motor with brake.

Improved operabilit y with the MNO2 (MEC NewOperation 2) programming software- The MEC original spring program MNO2 easily organizes
important statistics about the machine, including program flow,
operating status of each axis, inputs/outputs, jump, etc., as with
our other spring machines.
- The program editing function has greatly evolved, and thenavigation system function and touch screen make it easier tocreate programs and shorten the setup time.
- The program for number of coils allows change of the feed,
pitch, outer coil diameter, initial tension and wedge on theevolved pitch diagram screen, making it easier to adjust thebasic coils.
- For taper springs, you can control the rate of taper change
by inputting a numerical value from 0 to 100. The taper isleaner when closer to 0, and bigger when approaching 100.
In addition, it is also possible to perform load adjustment byslightly adjusting the value.
- The automatic function of coil length correction is based on thecapacitance length measurement method. The multi-functional
produc tion management system gives easy- to - c ontrol
production.

Program for number of coils (cylindrical coils)

By freely inputting numerical values for the pitch and outer coildiameter, you can easily adjust the compression spring program.
