3M™ Diamond Microfinishing Film 675L

Superfinishing systems

3M™ Microfinishing Films are used for finishing Cam and Crankshafts, trimming and finishing composite materials as well as general industrial deburring applications on hard materials. These Micron graded aluminium oxide mineral particles coated on a polyester film roll provide high tolerance precision finishes.

The sharp diamond coating and durable construction of 675L film can help significantly reduce abrasive usage by enabling slower abrasive feed rates. It may also allow you to start the superfinishing process with a finer grade of the 675L film, eliminating sequencing steps and the downtime needed to switch films.
