DHJ300 Silicon Steel Cutting Line High Precision Servo Driven
Reactor Core Cutting Machine
Product Overview
The DHJ300 Silicon Steel Cutting Line is a high-precision, servo-driven production line designed for reactor silicon steel cutting, punching, and sizing. Built for cold-rolled oriented and non-oriented silicon steel coils, the cutting machine delivers consistent accuracy, ultra-low
burrs, and stable high-speed performance for medium and small batch
production. This integrated line combines uncoiling, guiding, servo feeding, punching, and shearing in a compact footprint, making it ideal for factories with limited
space but strict quality requirements. With Delta PLC + servo control, carbide blades (HRC88–90), and Gcr15 hardened rollers, the DHJ300 cutting machine ensures reliable long-term operation
and minimal maintenance.
If you are looking for a reliable silicon steel slitter cutter, precision core cutting machine, or automated reactor steel processing line, the DHJ300 cutting machine is your cost-effective, high-accuracy
solution.

Selection Guide
Choose the DHJ300 Silicon Steel Cutting Line if:
- You process 0.23–0.35 mm cold-rolled silicon steel (oriented / non-oriented)
- Strip width is 25–300 mm
- You need ±0.05 mm/m length accuracy and low burrs
- Production volume is small to medium batch
- You have limited floor space (8 × 2.5 m)
- You prefer standard, easy-to-source components (Delta servo, domestic bearings, carbide blades)
If you need wider width, higher speed, or multi-head uncoiler, contact us for a custom silicon steel cutting line.
FAQ
Q1: What is the warranty of the DHJ300?
A: 1-year warranty after installation and acceptance. We repair normal-use faults
free of charge during the warranty period.
Q2: Do you provide installation and training?
A: Yes. We send 1–2 engineers for on-site installation, commissioning, and 3 days of free operator training. Buyer covers visa, airfare, accommodation, meals, and $150/person/day service fee.
Q3: What is the maximum coil weight it can handle?
A: 1.5 tons per head, suitable for standard silicon steel coils.
Q4: Can it process other metals besides silicon steel?
A: Optimized for 0.23–0.35 mm silicon steel. For other thin metals, contact us for customization.
Q5: How do you guarantee straightness for narrow strips (≤40 mm)?
A: Precision linear guides + adjustable vertical rollers ensure ≤0.2 mm / 2 m straightness for widths ≤40 mm.
