The medical device, medical implant, and surgical tool industries demand the highest quality components and the most reliable manufacturing processes given the critical nature of the end-use applications. Medically implanted devices often have complex geometries and are composed of stainless steel, titanium, and other superalloys, making them difficult to hand or electropolish. Smooth surfaces are desired for corrosion resistance, sterility, and reduced wear.Hip Medical Image

REM’s ISF®­­­ Process is an isotropic superfinishing process that can polish these demanding component applications and provide critical advantages to the medical industry.  By producing ultra-low Ra surface roughness (Ra<2 µin.) and producing a unique, non-directional, low skew/high flatness surface, the ISF Process is able to enhance part sterility by removing surface crevices (accumulation points for bacteria and other debris), increase resistance to fretting and other corrosion types, and improve blood-contacting performance in the form of reductions in hemolysis and thrombosis. Lastly, due to the unique controllability of the ISF Process linked to its chemical-mechanical polishing technique, critical part geometries are able to be maintained in a mass finishing-like environment that offers superior process control to manual operations.
