Tungsten Carbide Slitter Knives for Corrugated Cardboard | Circular Blades for Corrugator Machinery
$37.98
Achieve flawless, burr-free board separation with Panda Carbide’s High-Performance Tungsten Carbide Circular Slitter Knives. Specifically engineered for the punishing, high-speed environments of the corrugator industry's dry-end slitter-scorer machine sections, our solid carbide razor blades deliver pristine edge cutting and trimming quality across all flute profiles.
Manufactured using 100% virgin sub-micron tungsten carbide powder and consolidated through overpressure HIP sintering, our circular blades exhibit extreme edge retention and resistance to heat and paper-dust abrasion. By eliminating structural micro-chipping, Panda Carbide slitter knives ensure maximum production uptime, significantly reduce sharpening frequencies, and minimize paper waste on your factory floor.

4. Advanced Technical Solutions & Online Sharpening Guide
Q: How do Panda Carbide blades eliminate dust and burrs during high-speed slitting?
A: Our blades feature a proprietary mirror-polished cutting edge ( Ra ≤ 0.02 μm ). This ultra-smooth surface profile dramatically reduces friction between the blade flank and the moving cardboard fibers. By eliminating macro-roughness, the blade smoothly shears the paper matrix instead of tearing it, resulting in a completely burr-free edge with near-zero dust accumulation.
Technical Maintenance & CBN Grinding Optimization:
Online Sharpening: When using integrated online grinding stones or CBN (Cubic Boron Nitride) wheels, utilize a micro-feeding frequency. Because tungsten carbide is highly rigid, ultra-light, continuous dressing is superior to heavy intermittent force, protecting the razor edge from thermal micro-cracks.
Lubrication: Ensure that dust-extraction vacuum systems are cleared regularly to maintain air cooling over the cutting hub, preserving the blade's precise edge geometry.
5. B2B Commercial & Bulk Sourcing Support
Protective Packaging: Every circular slitter knife is coated in anti-rust oil, fitted with plastic edge guards, and securely vacuum-packed inside heavy-duty foam crates to ensure flawless delivery to overseas paper mills.
Bespoke Core Dimensions: We manufacture custom outer diameters, inner bore splines, and specific pinhole configurations based directly on your facility's mechanical blueprints.
