Metal finishing is a crucial last step in the sheet metal fabrication process. Finishing improves the aesthetic appearance of a part and reduces surface roughness for parts that need to mate or seal.
A: A machine surface finish chart is a reference document that categorizes different types of surface finishes based on their surface roughness. It helps in selecting the right finish for specific metal cutting or fabrication requirements by showing the range of surface roughness levels that can be achieved by different machining processes.
Standards for surface finish in sheet metal fabrication (e.g., Ra values) In technical drawings, surface roughness is often represented by numerical values indicating the characteristics of the roughness profile. The most frequently specified roughness parameters are Ra (average roughness) and Rz (mean roughness depth).
Types of Metal Surface Finishes. In this section, we will explore some of the most common types of metal surface finishes, including: Electroplating; Anodizing; Brushed Finish; Polished Finish; Section 2: Applications and Benefits Applications of Metal Surface Finishes. Metal surface finishes find applications in various industries.Xometry offers a wide selection of metal and plastic materials with various finishes and post-processing options.

Fabrication tolerances. Geometrical tolerances are specified in Annex B of BS EN 1090-2. Tolerances are grouped three distinct categories: Essential tolerances. These are the limits of permissible deviation for the mechanical resistance and stability of the structure and are used to support conformity assessment to BS EN 1090-1. We understand that surface finish is essential to an assembly’s appearance, performance, and compatibility with secondary finishing processes such as powder coating or painting. Sheet metal finish considerations aren’t inherently complicated, but overly large assemblies can introduce unexpected costs and logistical challenges.. One ASM customer . The stainless steel 4 finish is a more refined surface than the No.3 finish, which has soft glossy and fine lines. It is mechanically polishing based on a #3 finish with gradually finer abrasives. The final finish of #4 can be anywhere between 120 and 320 grit.
