High-quality Materials for Micro-finishing

Introducing the 3M Diamond Microfinishing Film Belt 675L, designed with the highest quality materials to provide exceptional micro-finishing results. This belt features micron-graded diamonds securely anchored to a durable polyester film backing. The polyester film backing is not only water resistant, but it also allows the abrasive to be used with a water or oil-based lubricant. This lubricant helps to wash away unwanted swarf and debris, ensuring a clean and efficient cutting process. Additionally, the lubricant helps to keep the abrasive running cool, preventing overheating and prolonging the life of the belt.

One of the standout features of the 3M Diamond Microfinishing Film Belt 675L is its color-coded grading system. Each belt is color coded according to its grade, making it easy for operators to quickly identify and select the appropriate grade for their specific application. This reduces the risk of selecting the wrong grade and ensures consistent and accurate results.

Tips for Achieving Desired Roughness Average

When it comes to micro-finishing products, achieving the desired roughness average (Ra) is crucial, especially when working with thermal spray coatings, carbides, ceramics, exotic alloys, or other composites. Operators must carefully consider the Ra requirements and the substrate material when selecting the grade of film for the 3M Diamond Microfinishing Film Belt 675L.

By taking into account the specific Ra requirements and the characteristics of the substrate material, operators can choose the appropriate grade of film that will deliver the desired surface finish. This attention to detail ensures that the micro-finishing process is optimized for maximum performance and quality.
