Product Description

Information

The CNC mattress spring coiling machine is an advanced, fully automated solution for producing double-cone mattress springs with high precision and efficiency. Unlike traditional machines that rely on mechanical cam systems, this model uses intelligent CNC programming and digital parameter adjustment through a user-friendly touchscreen interface. This ensures fast setup, simple operation, and consistent output quality without the need for mechanical adjustments.

With a production capacity of 90¨C100 springs per minute, the machine is built to support large-scale mattress manufacturing while maintaining stable performance. The integrated coiling, knotting, heat treatment, and spring alignment processes are executed automatically, delivering a seamless and reliable production flow.

Driven by a bus-type EtherCAT servo motor control system and a PLC motion controller, the machine guarantees precise operation, smooth motion, and superior energy efficiency. Its advanced electrical and mechanical protection systems provide strong self-protection capabilities, reducing downtime and extending machine lifespan.

In addition, the machine is equipped with remote monitoring and diagnostic functions, enabling manufacturers to track performance data, troubleshoot issues, and receive technical assistance through a network connection. This feature not only improves operational safety but also minimizes maintenance costs and enhances production efficiency.

Combining cutting-edge control technology, robust safety features, and high productivity, this CNC spring coiling machine is the ideal choice for mattress manufacturers seeking reliability, automation, and long-term value.
