Abrasive Mineral Options & Processing Guide

1. VSM Ceramic Grain (XK850X)

• Available Grits: P36, P60, P80, P120
• Key Features: Microcrystalline self-sharpening ceramic abrasive engineered for aggressive, high-pressure stock removal. Active top-layer grinding aid ensures cold cutting to prevent burn discoloration and workpiece tempering.
• Target Materials: Heavy stock removal on forged steels, high-tensile alloy steels, cast iron, and stainless steel pipe fabrication.

2. 3M Zirconia Alumina (577F)

• Available Grits: P40, P60, P80, P120
• Key Features: Continuous fracture self-sharpening zirconia grain on heavy YF-weight cloth backing. Provides rapid heat dissipation under medium-to-heavy grinding pressure.
• Target Materials: Stainless steel weld blending, structural carbon steels, non-ferrous alloys, and dense hardwoods.

3. Heavy-Duty Aluminum Oxide (AO)

• Available Grits: P100, P150, P180, P240/P320, P400/P600/P800, P1000/P1200
• Key Features: Economical, general-purpose abrasive with high-tensile polyester cloth backing for stable, tear-resistant performance.
• Target Materials: Furniture shaping, wood flooring, plastic deburring, and artificial stone finishing.

4. 3M Non-Woven Nylon Conditioning Fiber

• Available Grits: Brown P100–P150 (Coarse), Red P180–P240 (Medium), Blue P320–P400 (Fine), Grey P600 (Very Fine)
• Key Features: Three-dimensional open-web nylon structure impregnated with abrasive grains; removes surface scratches and oxide scale without undercutting or gouging the base metal.
• Target Materials: Uniform hairline/satin graining, edge deburring, and surface conditioning on stainless steel and aluminum.
