with reinforced clamp unit

Even when high -feed pressure
is required, a dual feed roller unit
will help you realize a stable line

higher quality products.

By strengthening the clamp
pressure compared to theconventional model, the machine
prevents coil runout during cutting.
This enables stable coil supply andensures the correct position during
the raising process.

Features
Achieving required quality for guide wires

The newly developed 2-point coiling unit disperses friction
during coiling and contributes to stabilization of the initialcoil tension. Furthermore, compared to the 1-point method,
the trace of the coil inner diameter is greatly reduced
without an arbor.

Supports automated production

Compared with the conventional coiling production
method, the automatic cutting ability structure after coilingenables continuous production of coils.
This saves about 90% of labor in one day's work.
In addition, the yield is improved because there is no extra
waste material generated during production.

Supports high-speed production
The optional rotary discharge shooter PR-2, which
receives the long coil wire, suppresses runout whenmanufacturing long coils, eliminates the problem ofdischarge methods, and supports high-precision coiling.

This machine automatically adjusts the amount of wiredrawn out and feeds it into the machine. As a result, in
additional to stable high-quality processing, the production
speed increases about 3 times* compared to conventionalcoiling with the core production method.

Features
Achieves stable coiling with a high-speed follow-up line
stand

It is possible to keep the feed pressure to the minimum without the tension
fluctuating, even when the material is suddenly accelerated or decelerated.
Therefore, stable spring processing is achieved without crushing the material.
The wire stand supports a maximum feed speed of 283 m/min. Even withlong length feed at high speed, troubles such as adjustment of the wire baseand material entanglement can be reduced, and tact time and wire payoff are
improved.
The wire stand maintains a stable wire supply by utilizing high-speed arithmetic
processing and 2-axis servo motors, such as turntable and feed axis.
