Abrasive Media Families & Processing Guide

1. 3M Trizact Cloth Belts (237AA & 305EA)

• Available Grades: A65, A30, A16, A6, A5, A3, and 6-Piece Assorted Mix Pack
• Microreplication Technology: Three-dimensional microscopic pyramids wear evenly to continuously expose fresh aluminum oxide cutting mineral, delivering consistent finishes with minimal heat buildup.
• Grade Conversion Guide:
  • A65: ~P280 equivalent (fine preliminary grinding)
  • A30: ~P600 equivalent (satin blending and uniform scratch refinement)
  • A16: ~P1200 equivalent (pre-mirror preparation)
  • A6: ~P2000 equivalent (high-gloss preparatory polish)
  • A5 / A3: ~P2500 - P3000 equivalent (ultra-fine micro-finishing)

2. Non-Woven Nylon Conditioning Belts

• Available Grades: P150 Yellow (Coarse), P240 Red (Medium), P400 Blue (Fine), P600 Grey (Very Fine)
• Features & Applications: Flexible three-dimensional open-web nylon structure impregnated with abrasive grains; ideal for straight-line satin graining, oxide scale stripping, edge deburring, and seamless weld blending without undercutting.

3. Seamless Wool Felt Polishing Belts

• Construction: 4-5 mm thickness jointless continuous ring structure
• Applications: Eliminates seam bump and chatter marks during high-speed rotation; pair with diamond paste, green rouge, or buffing compound for optical mirror finishes on stainless steel pipes, cutlery blades, and non-ferrous metals.
