Precision Slitting Machine Blades

Slitting Machine Blades: Basics, Types & Uses

What Are Slitting Machine Blades?

• Core cutting tools for metal coil slitting lines

• Cut wide metal coils (steel, stainless steel, aluminum, copper) into narrow strips of custom widths

• Used in metallurgy, metal processing, automotive parts, home appliances and hardware industries

• Their precision affects edge flatness, burr-free quality and production efficiency

Core Features

• Hard & Wear-Resistant: Made of Cr12MoV, SKD11, high-speed steel or cemented carbide; HRC 58-62 hardness; long service life

• High Precision: Micron-level tolerance; no burrs or curling on cut edges; no need for secondary processing

• Customizable: Can adjust outer diameter, inner diameter, thickness and edge angle to fit different slitting machines

• Stable at High Speed: Little deformation; no wobbling; consistent slitting size; less scrap

Main Types

• Circular Blades: Most common; disc-shaped; for regular slitting of steel, aluminum and stainless steel coils

• Irregular Blades: Custom design (stepped, beveled); for thick or hard metal coils

• Upper/Lower Matching Blades: Used together; standard for all slitting machines; fits all metal coils

Applicable Industries

• Metallurgy: Slitting steel, aluminum and stainless steel coils before delivery

• Metal Processing: Custom narrow strips for downstream customers

• Automotive & Home Appliances: Precision strips for stampings, casings and hardware

• Special Materials: Slitting galvanized, color-coated, copper and titanium strips

Key Processing Technologies

• Material: High-toughness alloy steel, high-speed steel or cemented carbide

• Heat Treatment: Vacuum quenching (uniform hardness, no breakage)

• CNC Machining: Precise cutting and grinding; strict tolerance control

• Edge & Surface: Custom edge angles; nitriding/TiN coating (reduce friction)

Daily Use & Maintenance

• Installation: Check for burrs; ensure blade and spindle are coaxial; tighten securely

• Adjustment: Set proper blade gap (too big = burrs; too small = more wear)

• Operation & Storage: Clean metal chips; rust-proof idle blades; store in dry, flat place
