CNC Machining Finishes

Parts in days anywhere in the USA.

CNC machining finishes can achieve different looks and functionalities for your project. Surface finishes enhance appearance, improve corrosion resistance, increase hardness, and minimize friction. Some standard finishes for CNC machined parts include anodizing, powder coating, polishing, plating, and painting. The choice of finish will depend on the intended use of the part and your preferences.

Choosing which machining finish is right for your project.

Choosing the right machining finish for your project involves carefully considering several factors. Different finishes may be more appropriate depending on the machined part’s intended use. For example, a position requiring high precision may require a finer finish, while an amount exposed to harsh conditions may require a more durable finish.

Other essential factors to consider include the type of material being machined, the type of machining process being used, and the cost and time constraints of the project. Some standard machining finishes include rough machining, which leaves a coarse finish for parts that require additional finishing, and fine machining, which is used for positions that require a high degree of precision.

Overall, the choice of machining finish should be based on a thorough evaluation of the project’s requirements and the capabilities and limitations of the machining equipment and techniques being used.
