Best Surface Finishes for CNC Machining

Boost that precision! Optimize your CNC machining results by seeking out the top surface finishes. With this list of key insights, you can guarantee yourself success in your next machining project. #CNCmachining #surfacefinishes #precision #quality

Aluminum Anodizing parts
Anodizing
Anodizing is a process that enhances the durability, toughness and hardness of a surface. It also provides resistance to wear and tear plus corrosion. This treatment is applied on mechanical, aircraft, automobile parts and precision instruments. There are different colors for anodizing such as clear, black, grey, red, blue and gold which give matte finish.
Bead Blasting
Bead Blasting

Bead blasting is a technique that creates smooth surfaces with a matte texture. Perfect for visual applications and compatible with many different types of materials, such as ABS plastic, aluminum, brass, stainless steel, and steel. You can even combine bead blasting with other surface treatments to improve the overall look.

Powder Coating
Powder Coating

An electrostatically applied, dry powder coating that is then cured with heat or UV light is known as a powder coating. It doesn't use solvents like liquid paint does. You can find it in aluminum, stainless steel, and steel options and they all come in black or any RAL code/Pantone number. There are two finish options too: gloss or semi-gloss.

Electroplating
Electroplating

Electroplating is used across industries like automotive for functional, decorative and corrosion purposes. It’s very popular to chrome-plate steel auto parts. For a smooth, shiny finish, aluminum, steel and stainless are common materials.

Polishing
Polishing

Discover the wonder of polishing, which makes surfaces all shiny and smooth. Some people do it by rubbing things, while others use chemicals to make them dazzle with a specular reflection. Diffuse reflections, though, may be reduced in some materials. For aluminum, brass, stainless steel and regular steel — there are various ways to achieve that gorgeous glossy finish.

Brushing parts
Brushing

Surface brushing is a treatment technique that can create decorative patterns on materials like ABS, Aluminum, Brass, Stainless Steel and Steel. It uses abrasive belts to give surfaces a satin finish so they look better when viewed.

It’s an ever-moving world, especially in the industry where manufacturing plants can be seen as large warehouses that have to keep up with the high demands of producing their products. For years, it seems like a custom-made piece was just a fantasy only available for the rich and famous. However, CNC machining services are quickly becoming popular in personalized manufacturing and rightfully so! This process produces unmatched quality and is known for being fast and flexible. In this blog we’re going to look at all of the different things that CNC machining can do for you and your products. From aerospace, automotive parts all the way down to healthcare and high-tech sectors no one is left behind from the help that CNC machining provides. It’s time to explore why this technology is making such an impact in manufacturing plants everywhere.
