The 200 One-cut Four-punch Cut-to-Length Line is a high-precision silicon steel processing system designed for continuous transformer core lamination production. It integrates leveling, feeding, multi-position punching, and shearing into a single automated workflow, enabling efficient transformation of raw coils into accurately formed laminations for transformer core manufacturing.
Built around a full-servo drive architecture and CNC-controlled system, the production line ensures stable operation under high-load conditions while maintaining consistent dimensional accuracy. It is specifically engineered for thin silicon steel sheets ranging from 0.23mm to 0.6mm, making it suitable for precision transformer core lamination processing.
By combining automation and synchronized multi-process handling, the equipment significantly reduces manual intervention and improves production continuity in transformer core fabrication.
The machine is developed to support stable, high-precision silicon steel processing under continuous production conditions. Its structure and control system are optimized for accuracy, durability, and operational efficiency in transformer core lamination production.
The full-servo drive system works together with a Finger CNC control unit to manage feeding, punching, and cutting operations with stable synchronization. This improves consistency across long production cycles.
Mechanical precision design combined with high-quality linear guide systems helps maintain burr height within ≤0.02mm, ensuring smooth and clean lamination edges suitable for transformer core manufacturing.
Multiple processes including uncoiling, leveling, feeding, punching, and shearing are completed in a continuous line, reducing downtime caused by manual transfer or separate processing steps.
The system is built with Delta inverters, HIWIN/AIRTAC linear guides, Taiwan ball screws, and Schneider/Siemens electrical components, supporting long-term stable operation in transformer core lamination processing environments.
Sensor-based monitoring allows real-time detection of material deviation, enabling automatic correction during processing to reduce errors and improve material utilization.

The equipment is widely used in transformer core lamination manufacturing where precision and production stability are critical.
Supports production of high-precision laminations used in transformer cores, helping ensure stable magnetic performance and low energy loss.
Used for cutting and punching silicon steel sheets for transformer cores, helping maintain accurate sheet dimensions, smooth edges, and consistent lamination quality.
Applied in transformer core lamination production, where stable punching accuracy, precise shearing, and repeatable output are required for core stacking and assembly.
Suitable for preparing silicon steel laminations used in step-lap transformer core manufacturing, supporting accurate feeding length and stable cutting quality.
The operation process is designed to ensure stable startup, continuous production, and long-term equipment reliability in transformer core lamination processing.
Before starting operation, ensure pneumatic pressure is maintained between 0.5–0.7MPa. Check mechanical fastening points and confirm system readiness.
Load silicon steel coils onto the uncoiling unit and configure processing parameters such as feeding length and punching settings through the Finger CNC system.
Perform a no-load test run to verify feeding accuracy, punching alignment, and cutting stability before entering full production mode.
After parameter confirmation, switch to automatic mode. The system will perform continuous leveling, punching, and cutting operations in sequence.
Regular inspection of hydraulic oil level, punch die condition, and lubrication system is required to ensure stable long-term operation and reduce wear.
Q1: How does the machine maintain a burr height of ≤0.02mm during high-speed shearing operations?
A: This exceptional edge quality is achieved through a combination of the ultra-rigid HIWIN/AIRTAC linear guides and Taiwan-made ball screws, which completely eliminate lateral blade deflection. Furthermore, the full-servo drive system ensures precise, instantaneous blade impact velocity, resulting in clean, micro-burr cuts even on the thinnest 0.23mm silicon steel sheets.
Q2: Can the Finger CNC control system be integrated with our existing factory production network?
A: Yes, the open-source architecture of the Finger CNC system allows for highly flexible custom programming and data exportation. It can be configured to communicate seamlessly with centralized production monitoring systems, enabling real-time tracking of feeding lengths, punching quantities, and overall machine efficiency.
Q3: What specific daily maintenance routines are required to keep the production line running optimally?
A: Daily maintenance is straightforward but crucial for longevity. Operators must ensure the pneumatic supply remains steady between 0.5–0.7MPa, regularly check the hydraulic oil levels, and visually inspect the punch dies for wear. The centralized lubrication system also requires periodic monitoring to guarantee all moving parts operate without friction.
Q4: How do you ensure the machine survives long-distance international shipping without losing its precision calibration?
A: After passing the strict load tests, the entire machine is treated with industrial-grade anti-rust solutions, vacuum-sealed to prevent moisture ingress, and securely anchored within heavy-duty, fumigated wooden crates. Critical moving components are mechanically locked in place to prevent any shifting or vibration damage during maritime transit.
Q5: What is the standard procedure if a component fails after the initial 12-month warranty period expires?
A: We provide lifelong technical support for all our machinery. Should a part require replacement after the warranty expires, our established global supply chain ensures the rapid dispatch of standardized components—such as Delta inverters or Schneider/Siemens low-voltage parts—at transparent, direct-from-manufacturer prices, accompanied by comprehensive remote installation guidance.
