Highlights
- Micron-graded diamond mineral delivers close tolerance precision finishes
- Great for medium stock removal
- Polyester film backing allows belt to be used dry or wet with water or oil-based lubricants
- An exceptional film for thermal spray finishing of contour / complex shapes
- Color coded to reduce the risk of error and mixing up abrasive grades
Designed with a strong polyester film backing and sharp diamond mineral, the 3M™ Diamond Microfinishing Film Belt 675L delivers fine finishes on hard metals like thermal spray coating, ceramics, carbides, chilled iron and granite.
Because of its unique construction, 675L film helps you achieve fast finish reduction in fewer passes
3M™ Diamond Microfinishing Film Belt 675L securely anchors micron-graded diamonds to a polyester film backing. Polyester film backings are water resistant, so the abrasive may be run with a water or oil-based lubricant, which helps wash away unwanted swarf and debris and keeps the abrasive running cool. The belts are also color coded by grade to help you reduce the risk of selecting the wrong grade.
Tips for Achieving Desired Roughness Average
Many Micro-finished products require a specific Ra, or roughness average, when applying to thermal spray coatings, carbides, ceramics, exotic alloys, or other composites. It is important for operators to consider these factors — Ra and substrate — when selecting the grade of film for this belt.
