180m/min High Speed Automatic Core Cutting Machine for 0.2-0.35mm Silicon Steel

High Speed Reactor Core Cutting Line | Automatic CRGO Silicon Steel Cut-To-Length Machine 

Product Overview

The DHJ300 automated reactor core cut-to-length line is purpose-built for manufacturing reactor laminations from CRGO grain-oriented silicon steel. Designed for high-volume core sheet fabrication, it performs automatic fixed-length shearing, with optional precision punching modules to satisfy diverse reactor core build requirements. Servo axes govern all cutting and punching actions across the line, delivering consistent dimensional stability and repeatable cutting quality. Equipped with ultra-hard tungsten carbide cutters and a PLC touchscreen control interface, this silicon steel processing line is intuitive to operate, offers extended service cycles and keeps ongoing maintenance expenses low. It serves as a reliable core fabrication solution for reactor manufacturers and electrical component producers worldwide.

Key Benefits

• High-Precision Servo Synchronization: Full servo drive architecture governs feeding, punching and shearing cycles. Feed accuracy holds within ±0.05mm per meter, guaranteeing uniform lamination dimensions and trouble-free core stacking.

• Long-Lasting Tungsten Carbide Tooling: Shear blades and punch dies are manufactured from premium carbide with HRC 88–90 hardness. Each tool set supports more than 5 million cuts before regrinding, cutting down tool replacement frequency and lowering production overhead.

• High Throughput Capacity: Line feed speed reaches up to 180 m/min. It maintains tight precision while running continuously, helping manufacturers raise daily output without sacrificing part quality.

• Broad Processing Window: Accommodates cut lengths ranging from 10 mm up to 9999 mm. Compatible with CRGO strips 0.22–0.35 mm thick and 40–400 mm wide, supporting most standard reactor core specifications.

• Simplified HMI Operation: The integrated touchscreen PLC lets operators save product recipes, start continuous auto-run and monitor live machine status. It minimizes manual setup errors and cuts labour input.

• Superior Cut Finish: Cutting burr is controlled strictly under 0.02 mm. Clean, smooth lamination edges reduce audible noise and no-load losses once the reactor is assembled.

Machine Layout & Standard Units

DHJ300 adopts a modular integrated frame that covers the full workflow from coil unwinding to finished sheet stacking.

• Hydraulic Decoiler: Hydraulic expansion mandrel fits coil inner diameters from 470 mm to 508 mm, delivering stable, controlled payoff.

• Heavy-Duty Machine Base: High-rigidity one-piece welded frame, engineered to resist deformation during long-cycle high-speed operation.

• Servo Feed Module: Precision servo feeding assembly ensures steady, slip-free material transport.

• Optional Punching Station: Add-on punching unit available for custom hole patterns required for reactor core assemblies.

• Precision Shear Station: Fitted with wear-resistant carbide shear blades for flat, low-burr cuts.

• Automatic Stacking Station: Neatly collects and stacks finished silicon steel laminations, removing manual sorting work.

• Central Control System: PLC + HMI touchscreen storage for multiple product recipes; one-click switch between different job parameters.
