Sheet Metal Cutting

Shengao Sheet Metal Cutting Blades are engineered from premium materials to ensure maximum durability and cutting performance:

• Tool Steel: High-carbon, high-chromium composition (1.5% C, 12% Cr) for general-purpose metal cutting with excellent edge retention
• High-Speed Steel (HSS): M2, M35, and M42 grades for enhanced wear resistance in high-temperature applications
• Tungsten Carbide: Extreme hardness (HRC 85-92) and superior wear resistance for cutting abrasive materials like stainless steel and titanium
• Ceramic & Cermet Coatings: TiN, TiCN, TiAlN coatings applied via PVD/CVD for enhanced edge retention, reduced friction, and corrosion resistance

Each material undergoes specialized heat treatment (HRC 58-65+) and precision grinding to achieve optimal hardness while maintaining toughness.

Selecting the appropriate sheet metal cutting blade depends on several key factors:

1. Material Type & Hardness: Different metals (stainless steel, aluminum, alloys) require specific blade compositions and hardness levels
2. Material Thickness: Thicker materials require blades with larger diameters and specialized geometries
3. Cutting Mechanism: Guillotine shears, rotary shears, and punching/notching applications require different blade types
4. Production Requirements: High-speed applications need blades with specialized coatings and tooth geometry
5. Cut Quality: Fine-cut applications require precision-ground blades with optimal clearance angles (1-5%) and rake angles (5-15°)

Our technical team can provide customized recommendations based on your specific material characteristics, machine specifications, and production requirements.

Proper maintenance extends blade life and ensures optimal cutting performance:

• Daily Inspection: Check edges for nicks, cracks, or dulling; verify blade alignment and parallelism within ±0.02mm
• Regular Cleaning: Remove metal debris and residue after each use to prevent buildup and corrosion
• Periodic Sharpening: Use CNC-controlled grinders for consistent edge geometry; typically 3-5 regrinds before replacement
• Proper Storage: Coat blades in rust inhibitor when stored; avoid dropping or impacting blades to prevent microcracks
• Alignment Checks: Ensure proper blade overlap (0.5-2mm) and minimal backlash to prevent material jamming

Shengao offers professional blade sharpening services and provides detailed maintenance guides with every purchase.
