Material and Performance
Abrasive: Utilizes alumina (Al₂O₃) or ceramic mixed abrasive, featuring both high hardness and wear resistance, capable of withstanding intense friction during metal processing.
Heat Dissipation Design: Optimized structure to enhance heat dissipation efficiency, reducing material deformation or grinding wheel wear due to high temperatures during operation.
Cutting Stability: Uniformly distributed abrasive particles ensure a smooth cutting process, reducing tremors and improving precision.
Application Domains
Industrial Scenarios: Automotive maintenance (such as brake disc grinding), steel structure cutting (such as I-beams, pipes), metal manufacturing (part refurbishment).
Material Compatibility: Suitable for stainless steel, carbon steel, alloys, etc. Not recommended for non-metals (such as stone, wood) to avoid abrasive blockage.
Safety Standards
Complies with ISO 60313 (Sanding Wheel Safety Specifications), passes the highest rotational speed test (e.g., 12,000 RPM), ensuring the anti-bursting capability during high-speed operation.
Technical Parameter Examples
Thickness: Approximately 3 mm (for cutting) to 6 mm (for rough grinding).
Diameter: 22.23 mm (compatible with standard angle grinder spindle).
Safe operating speed: ≥ 80 meters/second (indicated on the grinding wheel label).
Usage Tips
It is necessary to wear goggles and gloves, and ensure that the guard cover of the angle grinder is installed properly.
Avoid excessive lateral pressure to prevent the grinding wheel from cracking.
Replace it in time after passivation to prevent efficiency decline or overheating.
Synonymous Expressions
Metal cutting discs, angle grinder grinding wheel discs, stainless steel grinding discs.
Antonyms
Resin grinding wheels (for soft materials), diamond saw discs (for cutting with super-hard materials).
