Mesh Differentiation
Mesh count refers to the number of openings per linear inch on the sieve. A higher mesh count means finer abrasive particles with slower cutting performance and superior polishing effect. A lower mesh count means coarser particles, featuring fast material removal but leaving slight surface scratches.
Ideal for deburring, edge rounding and surface polishing of steel, aluminum, copper and brass workpieces.
Perfect for tiny connectors, pins and small electronic parts, no damage to delicate structures

No. Higher mesh count means finer particles for slower cutting and better polishing. Lower mesh count means coarser particles for faster cutting and higher material removal.
Fast cutting media is for deburring and removing oxide scale. Medium cutting is for surface trimming. Light cutting is for fine polishing to achieve high surface finish.
They work well with vibratory tumblers, rotary tumblers, centrifugal finishers and other mass finishing equipment.
Lower wear loss means better durability, longer service life and lower overall cost.
With diverse contact angles, it can reach gaps and holes of workpieces, reducing blind spots and delivering uniform polishing results.
The differences between 400-grit and 800-grit resin abrasive media mainly lie in performance and polishing results.
800-grit media features superior wear resistance, yet its cutting power is slightly weaker compared with 400-grit. Nevertheless, workpieces finished with 800-grit media deliver a much higher surface smoothness, making it ideal for processing scenarios with strict surface finish requirements.
Resin polishing media are medium-abrasive grinding stones that deliver gentle grinding without easily damaging workpieces. After processing, the workpiece surface generally forms an even frosted finish (snowflake surface) with a smooth and flat touch. It effectively removes surface imperfections and lays a solid foundation for subsequent precision finishing procedures.
Triangular resin media are recommended for workpieces with complex structures, abundant grooves and blind corners. Its special shape can easily reach intricate structures to polish every hidden corner.
Conical media perform excellently when polishing regular-shaped workpieces. Matching the abrasive shape to your workpiece profile will achieve optimal polishing performance.
