Surface Treatment
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.

Summary:
After shaping and joining, parts are often finished to improve appearance, durability, and functionality. Finishing may include deburring (removing sharp edges or burrs), grinding/sanding weld seams, polishing, painting, powder coating, anodizing, or other surface treatments.
