High-quality Materials for Micro-finishing

Introducing the 3M Diamond Microfinishing Film Roll 675L, a top-of-the-line product designed to provide exceptional results in micro-finishing applications. This film roll features a polyester backing that securely anchors micron-graded diamonds, ensuring optimal performance and durability. The strength and resilience of the polyester film backing prevent the abrasive from skidding or deflecting during use, allowing for precise and consistent finishing.

Waterproof Backing

One of the standout features of the 3M Diamond Microfinishing Film Roll 675L is its waterproof backing. The polyester film backing is resistant to water, enabling the use of a wet surface lubricant during the finishing process. This lubricant helps to wash away unwanted swarf and debris, keeping the abrasive running cool and maintaining its effectiveness. Additionally, the waterproof backing allows for slow abrasive feed rates and reduces the number of steps required, ultimately leading to cost savings.

Tips for Achieving Desired Roughness Average

When it comes to achieving the desired roughness average (Ra) for micro-finished products, experts recommend following a specific sequence of steps tailored to the substrate. For example, when applying thermal spray coatings on Tungsten Carbide, a Ra of 2.5 to 5 can be achieved by using the 3M Diamond Microfinishing Film Roll 675L with grades 74u, 45u, 30u, and 20u. It is crucial for operators to consider both the desired Ra and the substrate when selecting the appropriate grade of film for this belt.

Overall, the 3M Diamond Microfinishing Film Roll 675L is a reliable and versatile abrasive that delivers the desired finish without compromising the integrity of the substrate. Its high-quality materials and innovative design make it the perfect choice for all your micro-finishing needs.
