How to Select Resin Cutting Discs Wheels

Frist, Match Abrasive Type to Workpiece Material

The core abrasive grain determines cutting efficiency and surface finish. Our factory specializes in:

​1) Brown Fused Alumina (BFA): Ideal for carbon steel and cast iron. High toughness balances cutting speed and disc lifespan.
​2) Monocrystalline Alumina: Sharp-edged grains for stainless steel (solid bars/tubes) and titanium, reducing heat-induced discoloration.
3)  ​Coated Abrasives (ZrO₂/Al₂O₃): Applied on grains for aluminum/copper to prevent material adhesion.
4) Medium-Temperature Bonds: Enhance grain retention in high-RPM cutting of stone/concrete.

Material-Specific Recommendations

5) Stainless Steel Pipes (3-5mm wall): 0.8~1.2mm discs with monocrystalline alumina + zirconia.
6) Carbon Steel Plates: 2.5~3mm BFA discs with fiberglass reinforcement.
​7) Aluminum Profiles: 1.2mm mixed abrasive discs to minimize edge burrs.

Second,Optimize Disc Thickness for Precision
Thinner discs reduce kerf loss and heat generation:

​1) 1.0-1.9mm: Use monocrystalline/coated abrasives for stainless steel (solid bars) and non-ferrous metals.
​2) 2.0-3.0mm: BFA-based discs for carbon steel and cast iron, prioritizing durability over finish.

Third, Power Tool Compatibility
Abrasive-bond synergy requires proper grinder specs:

1) ​Monocrystalline Alumina Discs: Pair with ≥1,500W grinders to maintain 80m/s cutting speed.
​2) Coated Abrasive Discs: Compatible with brushless grinders (20,000-25,000 RPM) for vibration control.
