Made from high-quality materials: Cr12MoV, SKD11, high-speed steel, cemented carbide
Professional heat treatment (vacuum quenching, deep cryogenic treatment) achieves HRC58-62 hardness
Optional nitriding/TiN coating for better wear resistance and impact resistance
Reduces blade replacement frequency and production costs
Cutting edge tolerance controlled at micron level
Strict control of runout and end face runout
Flat, non-curled, burr-free coil edges after slitting
No need for secondary processing; faster downstream production
Customizable: outer diameter, inner diameter, thickness, cutting edge angle
Fits all slitting machine models
Supports circular, irregular shapes, and upper/lower blade sets
Meets different processing needs
Uniform heat treatment minimizes deformation
Stable operation (no wobbling) at high speeds
Consistent narrow strip sizes
Reduces product waste and improves coil use
Most common standard type (disc-shaped)
Adjustable blades for different cutting widths
Suitable for regular large-scale slitting (steel, aluminum, ordinary stainless steel coils)
Custom designs (stepped, beveled edges)
For hard-to-process materials (thick metal coils, hard alloy coils, special alloy strips)
Fits special slitting machines and high-precision needs
Designed for slitter machine installation positions
Used together to form a precise cutting pair (even cutting force)
Standard configuration for all slitting machines
Suitable for all metal coil specifications
Material Selection: High-toughness alloy tool steel/high-speed steel; high-end models use cemented carbide
Heat Treatment: Vacuum quenching for uniform hardness, better toughness, and no chipping/breakage
CNC Machining: Precision lathes/grinders for strict tolerance control (ensures assembly and slitting accuracy)
Custom Cutting Edge: Small angle for thin materials; large angle for thick/hard materials; polished for burr-free slitting
Surface Strengthening: Nitriding/TiN coating for higher hardness, less friction, and less material sticking
Check cutting edge for chips/burrs before installation
Ensure blade and spindle are coaxial
Tighten securely to avoid wobbling/loosening at high speeds
Adjust blade spacing and cutting gap based on material type and thickness
Too large gap = burrs; too small gap = more wear
Clean metal chips promptly to avoid scratching the cutting edge
Rust-proof idle blades; store in a dry, flat place
Avoid collisions
