What is Isotropic Finishing?

Simply put, Isotropic means "having uniform physical properties in all directions". In the mass finishing world, isotropic finishing refers to the surface of the component no longer showing any of the peaks, grinding marks, burrs or other imperfections commonly experienced in the machining, molding or casting processes. Isotropic mass finishing ensures a part's surface will have no discernible marks, lines or patterns. A microscope is often required to see any of the minute imperfections left on the surface of the finished part. We are experts in developing customized finishing programs for all your parts or components. From simple deburring to high-end titanium finishing, our combination of specialized tumbling media and centrifugal polishing expertise fill the finishing gaps in your overall part production process.

Why is Surface Roughness So Important in Manufacturing?

Surface roughness is a component of surface texture and plays an important roll in determining how an object will interact with its environment. Roughness is a good indicator of the performance of a mechanical component, since irregularities on the surface may form nucleation sites for cracks or corrosion. In tribology, rough surfaces usually wear more quickly and may have higher friction coefficients than smooth surfaces. For some applications, roughness may be desired to promote adhesion for cosmetic finish coatings such as painting, powder coating or plating.

Surface finish usually refers to a level of polishing or texture intended for the part or component surface. Some parts may require simple burr removal to allow them to enter the next phase of production. Other parts may require complete polishing if they are finished goods. The desired finish of a job depends on the product application, material, and type of finish your part requires.

Maintaining surface finish is critical for manufacturers and engineers to produce consistent and reliable production processes for each product. Where precision surface engineering is required, surface measurement may be a key element of maintaining control of the manufacturing, by monitoring the process to ensure it is within certain specifications. Mass finishing allows for the mechanical finishing of many parts simultaneously. Mass finishing may be used to deburr, descale, brighten, and polish parts. SURFACE INNOVATION has developed and documented processes to ensure each finished part exceeds the most demanding requirements to achieve consistent results.
