C-7100 7-Axis CNC Spring Coiling Machine for Automotive Compression Springs & Circle Washers – Wire Dia. 3-10mm

Product Description

• 7‑Axis Full Servo Synchronization – Seven independent servo axes work in concert to form complex geometries (variable diameter, variable pitch, multi‑angle bends) in one pass, ensuring high positioning accuracy and low rejection rates.

• Wide Processing Range – Covers wire diameters φ3.0–10.0 mm and max. spring O.D. 140 mm, suitable for automotive suspension springs, shock absorber springs, industrial compression springs, and more.

• Powerful Drive System – Fitted with a 61.5 kW high‑efficiency motor, delivering ample torque for continuous heavy‑duty operation, significantly boosting productivity even with thick wires.

• Flexible Customization – Supports tailored configurations including feed rollers, tooling, and fixtures to quickly adapt to diverse product specifications and special process requirements.

• Rugged & Durable Construction – Weighing 10 tons and measuring 3200×1700×2400 mm, the high‑rigidity cast bed minimizes vibration and ensures long‑term accuracy under severe working conditions.

• Intelligent Control Interface – Equipped with a user‑friendly HMI, allowing storage and one‑click recall of multiple spring programs, reducing changeover time and operator skill dependency.

FAQ

Q1: What is the maximum wire diameter this machine can process?
A: The XF‑7100 handles wire diameters from 3 to 10 mm (inclusive) and max. spring O.D. up to 140 mm. For larger diameters or O.D., please consult us for customised options.

Q2: What are the seven axes? Can they produce complex spring shapes?
A: The axes include wire feed, upper cut, lower cut, outer diameter, pitch, variable diameter, and auxiliary mandrel (configurable per process). The 7‑axis linkage enables variable pitch, variable diameter, end coils, bending angles, and other complex forms to meet demanding automotive requirements.

Q3: What is the delivery lead time? Do you provide installation and commissioning?
A: Standard lead time is 30–45 working days after order confirmation. We offer free on‑site installation, commissioning, and operator training, ensuring your production starts right away.

Q4: At 61.5 kW, is the power consumption high?
A: This is the peak rating; actual power consumption adjusts automatically with load. The servo‑driven system is energy‑efficient compared to traditional hydraulic or pneumatic designs, resulting in lower overall operating costs over time.

Q5: Can you customize non‑standard sizes or special features?
A: Absolutely. With extensive customisation experience, we can modify tooling, feeders, or even add auxiliary axes according to your prints or samples. Feel free to send your drawings for a tailored proposal.
