Isotropic Superfinishing Services

Cleveland Black Oxide has partnered with REM Surface Engineering to offer superfinishing services to customers.

REM Surface Engineering's ISF Process® generates a non-directional low Ra surface. It employs mass finishing equipment in conjunction with accelerated refinement chemistries that are non-hazardous and environmentally friendly.

Among its many benefits, an ISF surface reduces friction and wear, increases part durability, and improves corrosion resistance. The process has proven applications in many industries including aerospace, automotive, gearing & bearings, medical, military, motorsports, off-highway and power generation.

The ISF Process® produces a surface that has several key advantages over other "superfinishing" techniques. The resulting surface is asperity free, with a non-directional (isotropic) texture. The surface has an increased bearing ratio and enhances the lubricant retention properties of the mating surface.
