What is Mechanical Finishing

Mechanical finishing is a process that involves generation of different-looking surface textures on metal by buffing, brushing, tumbling, or bead blasting the surface. 

Mechanical finishing is a process that encompasses a range of different-looking surface textures on metal by buffing, brushing, tumbling, or bead blasting the surface. With Aerospace Metals, the process is as easy and simplified as possible, thanks to our extensive network of trusted, expert manufacturers.

Mechanical finishing is great for achieving different textures, and its benefits lie in the aesthetic appeal of the material that it provides. This type of finishing is also a great choice for covering and blending any imperfections or unwanted lines and marks that might appear as a result of the manufacturing process.

Mechanical Finishes

Ball Burnish

The action of a hardened ball against a softer, flat plate illustrates the process of burnishing. If the ball is pressed directly into the plate, stresses develop in both objects around the area where they contact, this method creates the Ball Burnish effect. 


Sandblasting is a process wherein a stream of sand is driven by a jet of compressed air or by water against a surface. This creates a powerful abrasive action that can clean and abrade any surface put under the jet of these abrasive particles. 

Tumble / Deburr

Tumble finishing, also known as tumbling or rumbling is a technique for smoothing and polishing a rough surface on relatively small parts. In the field of metalworking, a similar process called barreling, or barrel finishing, works upon the same principles.


Mechanical Finishes Overview

The process of mechanical finishing usually involves an abrasive component that helps create the desired texture, whether it’s a mirror finish or a rough-looking one. Depending on the type of media (abrasive) that is used, mechanical finishing will produce different textures.

Industries that use Mechanical Finishes

Among the industries that use Mechanical Finishes: automotive, aerospace and defense, industrial machinery, medical, robotics, energy, and R&D are the ones that stand out. However, Mechanical Finishes also makes other manufacturing industry processes possible, such as manufacturing molds for Injection Molding.
