High-quality Materials for Micro-finishing

3M™ Diamond Microfinishing Film Belt 675L is designed with micron-graded diamonds securely anchored to a polyester film backing. The water-resistant polyester film backing allows the abrasive to be run with a water or oil-based lubricant, which helps wash away unwanted swarf and debris and keeps the abrasive running cool. Additionally, the belts are color coded by grade to help reduce the risk of selecting the wrong grade.

Tips for Achieving Desired Roughness Average

When applying to thermal spray coatings, carbides, ceramics, exotic alloys, or other composites, many micro-finished products require a specific Ra, or roughness average. It is important for operators to consider these factors – Ra and substrate – when selecting the grade of film for this belt.
