CNC Machining Surface Finishes
We offer various finishes to make the surfaces glamorous and enhance the functionalities of workpieces. Let’s discuss the most common among them one by one;
As Machined
This machined finish is rough and shows tool marks. It is the simplest form of surface treatment. without additional finishing or polishing.
Anodizing
It creates a protective oxide coating on aluminum, enhancing corrosion resistance, hardness, and allowing for dyeing in various shades, thereby improving performance and appearance.
Polishing
It creates a smooth surface by removing flaws with abrasives, hence resulting in high gloss mirror finishes. Its major application is for aesthetic purposes while reducing friction.
Brushed Finish
This texture can be achieved by rubbing abrasive pads on the surface. It gives it a matt appearance with grain directionality.
Sandblasting
Sandblasting cleans surfaces by propelling high-speed particles, resulting in a dull matte finish that enhances grip and prepares CNC parts for further finishing.
Electropolish
This process involves removing a material layer from a metal surface by electrochemical means. It improves smoothness and corrosion resistance. It’s mostly used on stainless steel.
Alodine
Alodine finish for CNC machining involves applying a chromate conversion coating to aluminum, enhancing corrosion resistance and improving adhesion for subsequent coatings.
Heat Treatment
This is when you heat metals before cooling them to change their properties, such as strength, hardness, etc. Most of it deals with improving mechanical properties in metals.
Tumbling
Tumbling involves putting components into a rotary barrel containing grit media to smoothen and polish them. This technique is efficient in cleaning and deburring ( removal of burrs) components.
Powder Coating
Powder coating involves spraying a dry powder onto surfaces and heating it to form a hard, durable, and evenly colored finish.
Electroplating
Electroplating is a process that uses electrical current to deposit a metal layer onto a surface, enhancing its appearance, corrosion resistance, and wear properties.
Black Oxidize
Black oxide coatings give certain metals dark finishes. They are more resistant to mild oxidation forms often sought for visual-only purposes.

Applications
Prototyping
Rapid Prototyping
Designers and engineers use CNC machines to prove the viability of their ideas before going into mass production. This design process allows adjustments and improvements if there’s an error in the actual product performance.
Production
Mass Production
Once a design becomes final, CNC machines can produce large numbers of the same parts with uniform quality and precision. Even if thousands of identical components need to be fabricated rapidly, it’s not a big deal for a CNC machine.
Aria Manufacturing
CNC Machining
Network
CNC machining is a subtractive manufacturing process that’s accomplished with the help of high-grade precision cutting tools and CNC Machines.
We use these implements to remove layers of raw material from a workpiece. The piece can then be recast into all manner of shapes and sizes to create a unique and custom cnc machining part or product.
With our own CNC workshop in Dongguan Changan, we have dozens of 3-axis, 4-axis and 5-axis CNC machines, and cooperate with other companies all over China.
In addition to CNC machines, we have grinding machines, wire-cutting machines and EDM machines that allow us to handle complex designs and produce precision parts with tolerances of 0.01mm.
Our automated production lines ensure high efficiency and fast delivery, helping us meet client demands while maintaining quality and accuracy.

FAQS
CNC machining is a wide-ranging manufacturing category involving multiple computer-managed processes. The objective is to remove enough raw material from a piece to achieve a state of near completion.
Aria is a professional CNC machining manufacturer in China, The reliability and precision of high-tech tools powered by sophisticated software programs give CNC machining the ability to quickly generate prototypes and complicated end-use parts having exceptionally tight tolerances. with low cnc machining costs from Chinese.
CNC machining is a subtractive manufacturing process. When the material is added instead of removed, it’s called an additive manufacturing process. Examples of subtractive CNC machining include specialized applications such as CNC milling services, turning, surface grinding, and EDM. An example of additive CNC machining is 3D printing.
Computer-aided design (CAD) files are digital records containing 3D designs and information about materials, processes, tolerances, and other variables. A digitally controlled CNC machine must always contain a file of the part design that controls it.
The spinning motion from the CNC machine’s cutter will leave visible tool marks. Although they stand ready for immediate service, they can be further refined with anodizing, painting, polishing, and plating.
