CNC Circular Winding Machine

KX-CNC88J CNC Circular Winding Machine

The KX-CNC88J CNC Toroidal Winding System, an original innovation by KioXia Light Ring Equipment Group Co., Ltd., is specifically engineered to meet the sophisticated technical benchmarks of the voltage transformer sector. This high-precision apparatus incorporates several advanced features designed for high-performance manufacturing:

1. Structural Integrity and Performance Optimization

Designed for pre-treated R-shaped enclosed iron cores, the system utilizes a specialized supporting ring to facilitate direct secondary coil winding. By eliminating the requirement for core segmentation (cutting), the machine preserves the magnetic properties of the core, thereby enhancing the transformer's comprehensive electrical efficiency. This non-invasive approach allows for more compact transformer dimensions, resulting in significant material cost reductions and improved economic output.

2. Advanced Control Architecture

The platform integrates industry-leading PLC logic, offering a multifaceted yet user-friendly operating environment. Core functionalities include:

• Operational Versatility: Supports bidirectional winding, automated counting, and precise positioning.
• System Protection: Features integrated power-failure recovery, wire-breakage detection, and emergency braking.
• HMI Interface: A high-resolution touch panel provides real-time monitoring of processing states, with localized display options for wire gauge, rotational velocity, turn counts, and layer data.
• Drive Mechanism: The primary spindle utilizes frequency-conversion technology for stepless speed modulation, characterized by a high-torque, low-noise transmission chain. Operators can toggle between automated speed presets and manual foot-pedal regulation for maximum flexibility.

3. Precision Engineering and Motion Control

• Micrometer-Scale Accuracy: Wire distribution is managed by a high-performance stepper motor paired with a precision ball spline, achieving control resolutions as high as 0.001mm.
• Synchronized Tracking: Utilizing an optical rotary encoder, the system traces rotation and angular signals in real time. This ensures the main spindle and wire-laying mechanism remain perfectly synchronized, maintaining a marginal error rate within 0.1%.
• Tension Management: To resolve common manufacturing challenges such as wire fatigue or loose coil density, the system incorporates a premium damping mechanism. This ensures a constant, stabilized tension profile, preventing fluctuations that lead to wire breakage or insulation displacement.

4. Versatility and Industrial Application

The KX-CNC88J is distinguished by its space-efficient footprint and broad processing range. The system is highly adaptable, allowing for rapid adjustments based on core and framework dimensions. By utilizing modular clamping interfaces, it can be reconfigured for various casting voltage transformer specifications. It stands as an essential utility for the production of R-shaped enclosed core transformers and remains the preferred choice for high-tier electrical engineering applications.
