Product Description
826 8-axis CNC High-speed Spring Coiling Machine is composed by 8 Japan Yaskawa motors and a Taiwan control system. Each axis can work independently and synchronously. Our design team made a lot of improvement and innovation with more functions and a higher degree of automation. This updated machine can form the spring within one minute, featuring easy operation, high precision, and low noise. It can save much testing spring time and reduce the cost of raw materials.

Frequently Asked Questions
Q
What is the difference between the KCT-816 and KCT-826 models?
The primary differences lie in wire diameter capacity, outer diameter, pitch, wire feed speed, and motor power. The KCT-826 handles thicker wire (Φ0.8–3.0mm vs Φ0.3–1.6mm), produces larger springs (up to Φ70mm), and features more powerful servo motors, making it suitable for heavier-duty spring production.
Q
What cutting methods does this CNC spring coiling machine support?
The machine supports three cutting methods: straight cutting, subtend cutting, and rotary cutting. This flexibility allows it to accommodate a wide variety of spring types and production requirements.
Q
Which servo motor brand is used in these machines?
Both the KCT-816 and KCT-826 use 8 Japan Yaskawa servo motors, combined with a Taiwan control system. Yaskawa motors are renowned for their reliability, precision, and long service life in industrial automation applications.
Q
Can the machine measure spring dimensions automatically?
Yes. The machine can be equipped with a Camera Spring Length Gauge as an optional upgrade to replace the traditional length gauge. This system is capable of measuring both spring length and spring diameter automatically, improving quality control and reducing manual inspection time.
Q
What power supply is required for these machines?
Both models require a 3-phase / 380V power supply at 50/60Hz. Please ensure your facility's electrical infrastructure meets these requirements before installation.
Q
How long does it take to form a spring on this machine?
Thanks to its high-speed design and advanced 8-axis synchronous control, the machine can complete spring forming within one minute. This significantly reduces testing time and raw material costs compared to conventional spring coiling machines.
