About the Process

Electropolishing is an electrochemical process used to improve the surface finish of a part by removing material to level microscopic peaks and valleys. This process can polish, passivate, and deburr the parts. This process works the opposite way than that of plating processes, as the part acts as the anode in the reaction. As the current passes through the part (anode), the surface is oxidized and dissolved in the solution to the cathode.

Electropolishing is very useful in polishing irregular parts with hard to reach surfaces. Additionally, only a small amount of material is removed, so tolerances will not be greatly affected by this process.

Boring vs. Drilling vs. Reaming: A Guide to Precision Hole Machining

High-quality hole machining is critical for manufacturing parts with tight tolerances. Holes need to align with precision and accuracy, especially for functional assemblies and engineering fits. Drilling, boring, and reaming are distinct machining processes used to create or refine holes, each offering different levels of precision and surface finish. However, these terms are often mistakenly […]

FictivMade: Detailed DFM Analysis

Design for Manufacturing (DFM) is a critical component of product development that can make or break your product design. It can be integrated early and often in the process as design revisions are made, ensuring the designer and manufacturer are aligned. However, it can often be more complex and time-consuming than expected. At this stage […]
