High-quality Materials for Micro-finishing

Introducing the 3M™ Diamond Microfinishing Film Roll 675L – the perfect solution for your micro-finishing needs. This product is designed with high-quality materials that ensure a superior finish every time.

The micron-graded diamonds are securely anchored to a polyester film backing, which is known for its strength and resilience. This backing keeps the abrasive from skidding or deflecting when run, ensuring that the superabrasive belt stays taut and tough. Additionally, the belts are color coded by grade to help you reduce the risk of selecting the wrong grade.

Waterproof Backing

The polyester film backing is also water resistant, allowing the abrasive to be run with a wet surface lubricant. This helps wash away unwanted swarf and debris and keeps the abrasive running cool. When used in roll form for a process like superfinishing, the 675L roll enables slow abrasive feed rates and requires fewer steps, reducing costs.

Tips for Achieving Desired Roughness Average

Many micro-finished products require a specific Ra, or roughness average. To obtain the desired Ra when applying thermal spray coatings, experts recommend following a unique sequence of steps tailored to the substrate. For example, a Ra of 2.5 to 5 on Tungsten Carbide will likely require a film with grade 74u followed by films 45u, 30u and 20u. It is important for operators to consider these factors – Ra and substrate – when selecting the grade of film for this belt.

Overall, this micron-graded diamond abrasive delivers the desired finish without compromising the integrity of the substrate. Its strength and versatility make it a suitable abrasive for your finishing needs.
