Abrasive Mineral Options & Processing Guide

1. VSM Ceramic Grain (XK850X)

• Available Grits: P36, P60, P80, P120
• Key Features: Microcrystalline self-sharpening ceramic grain 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 bevel grinding on forged knife blades, hardened carbon steels, high-tensile alloy steels, 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 (aluminum, brass), and dense hardwoods.

3. Heavy-Duty Aluminum Oxide (AO)

• Available Grits: P40, P60, P80, P100, P120, P150, P180, P240/P320, P400/P600/P800, and Dry Assortment Packs
• Key Features: Economical, general-purpose abrasive with high mechanical tensile backing for stable tracking and tear resistance.
• Target Materials: General metal deburring, blade profiling, woodworking, plastics, and artificial stone finishing.

4. 290x50 mm Expander Wheel Compatibility

Precision-sized to slip directly onto 290x50 mm centrifugal rubber expander wheels and pneumatic drum sanders for curved workpiece and pipe polishing.
