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.
- 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
What is the 3M™ Diamond Microfinishing Film Belt 675L used for?
The 3M™ Diamond Microfinishing Film Belt 675L is designed to provide precise finishes on hard materials with high accuracy and consistency.
Can the product be custom cut to a specific size?
Yes, we offer customization services where you can request your desired size of belts or sheets that fit your machine needs. Contact us and our team will assist you further with this inquiry.
How long does each belt last before needing replacement?
The life expectancy of each belt depends on several factors including the material being worked, the operating conditions, and other variables. However, in general, our customers report that our diamond film belts tend to last longer than traditional abrasives due to their durability. If you have more questions regarding this topic feel free to ask!
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. By doing so, the desired roughness average can be achieved.
