675L film allows target finishes to be achieved in fewer passes for greater productivity
High-quality Materials for Microfinishing 3M™ Diamond Microfinishing Film Roll 675L securely anchors micron-graded diamonds to a polyester film backing. Known for its strength and resilience, the polyester film backing makes it tough so that it can withstand heavy-duty finishing. The rolls are also color coded by grade to help you reduce the risk of selecting the wrong grade.
Waterproof Backing Polyester film backings are also water resistant, so the abrasive may be run with a wet lubricant, which helps wash away unwanted swarf and debris and keeps the abrasive running cool. When used in roll form for a process like superfinishing, our 675L roll enables slow abrasive feed rates and requires fewer steps, because of its durability, which in turn can reduce costs.
Achieving the Desired Roughness Average Many microfinished products require a specific Ra, or roughness average. To obtain the desired Ra when applying thermal spray coatings, we recommend following a unique sequence of steps tailored to the substrate. 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.
