Sinto Surface Technologies has the process capability to super finish Aerospace, Medical Implants and other components requiring highly polished surfaces. The basic process routinely achieves surface finishes of 20 micro inch / 0.5 micrometer surfaces and can be modified to achieve 10 µin / .25 µm Ra surfaces or better. Sinto Surface Technologies processes employ proprietary media size and composition selected to achieve the best possible results taking in to consideration both the part material and geometry.
Our process does not utilize any chemicals that could affect or attack the grain structure of traditional or advanced alloys or materials. Super finishing can be tailored to the specific part geometry with careful attention to assure no foreign objects during processing can enter the internal passages or cavities of components, ensuring that only the external surfaces of the component are polished. The process can be used to improve the surface finish of machined components, cast and forged components, and coated substrates. We currently process a variety of components with varying alloy compositions ranging from soft to high hardness substrates and geometries.
- Robust process that can develop highly polished substrates with a finish of <10Ra efficiently and affordably.
- Sinto Surface Technologies specializes in this capability at our Wallingford Plant and can provide these services through our network of facilities in the Northeast, Midwest and Southeast.
- Allows for “One Purchase Order” approach to surface processing needs, as super finishing typically is a post-process for other surface modification processes and techniques.
