CNC Machining Service China. we always serve with offering you a variety of CNC machining services including milling, turning, EDM and wire EDM, surface grinding and much more. Applying our excellent imported 3, 4 and 5-axis CNC machining centers, our skilled machinists can make turned and milled parts using a wide range of plastic and metal materials.

CNC machining is used to produce custom parts with strong strength and tight tolerance, it is suitable for both high volume production and one-off jobs. In fact, CNC machining is currently the most cost-effective way for producing metal prototypes. Because of those advantages, it has been widely used in many areas.

Surface Finishing for CNC Machined Parts

Anodizing

Anodizing refers to the electrochemical oxidation of metals or alloys. Aluminum and its alloys form an oxide film on aluminum products (anodes) under the action of applied current in the corresponding electrolyte and specific process conditions. Anodized finishing can not only improve surface hardness and wear resistance of aluminum, but also prolong the service life and enhance its appearance. Anodizing has become an indispensable part of surface treatment of aluminum. It is the most widely used finishing applied to aluminum parts after CNC machining.

Sandblasting

The process of cleaning and roughening metal surfaces by the impact of high velocity sand flow. This method of surface treatment for aluminium parts can make the surface of the workpiece get a certain degree of cleanliness and different roughness, and improve the mechanical properties of the workpiece surface, thus improving the fatigue resistance of the workpiece, increasing the adhesion between the workpiece and the coating, prolonging the durability of the coating film, and also conducive to the coating. This process is often seen in Apple’s products, and is increasingly used in existing TV shells or mid-frames.

Polishing

 

By means of mechanical, chemical or electrochemical methods, the surface roughness of the workpiece is reduced to obtain a bright and flat surface processing method. The polishing process is mainly divided into mechanical polishing, chemical polishing and electrolytic polishing. Aluminum parts with mechanical polishing and electrolytic polishing can approach the mirror effect of stainless steel, giving people a feeling of high-grade, simple, fashionable future (of course, easy to leave fingerprints so need more care).

CNC Machining Application

CNC machining is highly flexible, quick turnaround and economical manufacturing method for making custom metal or plastic precision parts. It is widely used in many areas, such as aerospace, aircraft, marine,  where there is a need for custom parts, there may be a need for CNC machining.

As CNC machining is widely required by many companies, especially those who design new projects. They need CNC machining to realize one or several parts of their projects. So they need to outsource for custom machining services. We have noticed that, as years go on, more and more customers are seeking for CNC machining services in China. They come from all over the world.
