- Predictable Robotic Finish Quality
Product Description
3M Trizact Cloth Belt 307EA is a structured abrasive cloth belt with micron-graded aluminum oxide formed into microreplicated pyramids for controlled metal finishing and polishing. As the pyramids wear under medium pressure, fresh mineral is exposed to maintain a predictable cut and fine finish. A flexible rayon-cloth backing follows contoured surfaces, while the resin bond and grinding aid help limit delamination, heat buildup, warping, and discoloration. The film-media splice supports smooth belt travel with fewer chatter marks. This construction suits intermediate finishing, fine polishing before plating or buffing, and robotic finishing on hard metals such as carbon steel and stainless steel.
Key features
- Self-renewing abrasive pyramids: Microreplicated structures expose fresh micron-graded aluminum oxide as they wear.
- Flexible rayon-cloth backing: The backing follows contoured surfaces and supports controlled medium-pressure grinding.
- Heat-controlled fine finishing: A grinding aid helps limit heat buildup, warping, and discoloration on hard metals.
Applications
Suitable for intermediate finishing, fine polishing before plating or buffing, carbon- and stainless-steel finishing, and robotic polishing on compatible belt equipment.
