Abrasive Media Families & Processing Guide

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

• Available Grades: A65, A30, A16, A6, A5, A3, and 12-Piece Assorted Mix Pack
• Microreplication Technology: Three-dimensional microscopic pyramids wear evenly to continuously reveal 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), and 4-Piece Assorted Mix Pack
• Features & Applications: Flexible three-dimensional nylon mesh impregnated with abrasive grains; ideal for stainless steel hairline graining, oxide stripping, deburring, and seamless weld blending without gouging.

3. Seamless Wool Felt Polishing Belts

• Construction: 3-4 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 flawless optical mirror finishes on stainless steel pipes and knife blades.

4. Expander Wheel Working Compatibility

Engineered to mount directly onto 290x50 mm rubber expander wheels and centrifugal drums for portable grinding and curved pipe polishing.
