22mm OD CNC Spring Coiling Machine 350pcs/Min Spring CNC Machine

We Can Produce A Two-Axis CNC Spring Coiling Machine With A Maximum Outer Diameter Of 22 Mm.

Product Introduction

This two-axis CNC spring machine demonstrates outstanding adaptability and high efficiency in the production of small springs. It can produce springs with a maximum outer diameter of 22mm, with wire diameters ranging from 0.15 to 2.5mm. Through multiple precision guiding devices and adjustable mandrels, it can manufacture a full range of products from micro compression springs to small extension springs. This wide specification coverage precisely meets the processing needs of various industries such as electronic components, precision instruments, and small machinery for small-sized springs: In 5G communication modules, it can produce micro compression springs with a height of only 3mm and a rebound precision error ≤ 0.02mm, ensuring stable circuit contact; in the field of high-end medical devices, through a closed-loop control system that corrects winding angles in real-time, it can manufacture precise extension springs that meet ISO 13485 standards, satisfying the stringent requirements for reliability in devices such as pacemakers.

In terms of production efficiency, it stands out remarkably, achieving a maximum production speed of 350 units per minute. Combined with its unique continuous wire feeding system and automatic cutting mechanism, the actual production rhythm is increased by 40% compared to traditional equipment, meaning it can process up to 21,000 springs per hour, significantly shortening the cycle of bulk production. Such efficient operation capability stems from the strong combination of core components—the imported Japanese servo motors equipped with rare earth permanent magnet synchronous technology, which have a positioning accuracy of ±0.001mm and a high-speed response capability of 3000rpm, coupled with high-precision planetary reducers, ensuring precise control over each coil diameter during the spring winding process, effectively avoiding dimensional deviations caused by power fluctuations. The Taiwan computer controller, equipped with a 32-bit ARM processor, supports direct import of DXF files and G-code programming. Operators need only input key data such as wire diameter, number of coils, and pitch, and the system will automatically generate the optimal machining path based on an internal library of 128 sets of process parameters. Through the human-machine interface, production status can be monitored in real-time and parameters adjusted, reducing manual operation errors and enhancing flexibility in changeover production, thus enabling rapid programming and efficient production of complex springs.

Moreover, the machine maintains excellent stability even at high speeds, with a cast iron body optimized using finite element analysis and linear rolling guide pairs, combined with an intelligent load feedback system, keeping vibration within 0.01g, significantly reducing the impact of vibrations on machining accuracy. The machine also features non-contact laser diameter gauges and visual inspection modules, capable of measuring 12 critical parameters such as spring outer diameter and free height in real-time during production, and automatically correcting machining errors through a closed-loop control system, ensuring that key indicators such as verticality and end face flatness of finished springs meet industry high standards. For enterprises pursuing small batch multi-variety or large-scale standardized production, this two-axis CNC spring machine, with its flexible production capacity and cost-effectiveness, is undoubtedly an ideal choice for balancing efficiency, precision, and cost.
