Steel Surface Finishes | Precision Grinding, Inc

Steel surface finishes are often an important aspect of custom machine parts. Sometimes steel surface finish is also referred to as surface texture or surface roughness. The surface finish of a machine part may be important to reduce friction with other machine parts or to improve the aesthetics of the part. Surface finish measurements (RMS, Ra

The Basics of Surface Finish | GD&T Basics

Surface finish is highly dependent on the process used to manufacture the part, and very smooth surface finishes usually require additional processing such as grinding or polishing. Since additional processing will add additional cost, it is important that the engineer or designer does not impose unnecessarily low roughness requirements

Jul 14, 2020 Surface roughness is an often-overlooked dimensional aspect of the manufacturing process. While more focus is generally given to the composition of a part and its strength, or to its measured dimensions and tolerances, a surface that is too rough can result in increased friction and premature failure of a part

Surface Finish is a measure of the overall texture of a surface that is characterized by the lay, surface roughness, and waviness of the surface. Surface Finish when it is intended to include all three characteristics is often called Surface Texture to avoid confusion, since machinists often refer to Surface Roughness as Surface Finish
