Surface Finishes For CNC Machining
| As Machined | The surface is left untreated, retaining visible tool marks from the machining process. |
| Sandblasting | Used for cleaning, roughening, and enhancing the appearance of workpiece surfaces. It also improves surface adhesion and lubrication retention. This process is widely applied in metalworking, casting cleanup, and surface pretreatment operations. |
| Shotblasting | A widely used surface treatment process, suitable for roughening surfaces, deburring, removing oxide layers, enhancing texture, and improving the structural strength of materials |
| Wire Drawing | A surface treatment that gives the metal a directional, matte metallic texture through processing, resulting in a non-mirror finish. |
| Passivation | This removes surface contamination, increases corrosion resistance, reduces the risk of product contamination, and allows you to extend system maintenance intervals. |
| Logos printing | Customized logos, symbols, and text can be added to both prototypes and production parts using various methods. We offer services such as laser marking and silkscreen printing to meet diverse branding and functional requirements. |
| Anodizing | is an electrochemical surface treatment process commonly used on aluminum and its alloys. It is designed to enhance the material’s corrosion and wear resistance while also improving its aesthetic appearance. |

Overview of CNC Machining
What’s CNC machining?
Computer Numerical Control (CNC) machining is a precision subtractive manufacturing process in which machine tools are controlled by computer programs. In this process, the computer driven machines remove excess material from solid blocks of metal, plastic, composites, and other materials to achieve the final design in various shapes and dimensions. This technique can be used to produce a wide variety of precision components. Common CNC machine tools include vertical milling machines, horizontal milling machines, lathes, and gantry milling machines.
How does CNC machining work?
Our engineers first use the CAD files you provide to build a 3D model of the part. This model is then imported into CAM software, where they select the appropriate cutting tools based on the drawing’s critical dimensions, tolerances, and features, and configure the cutting parameters (spindle speed, feed rate, depth of cut) along with an optimal toolpath strategy. The CAM software generates a series of standardized instructions (G code, M code, etc.) that precisely control the machine’s axis movements, spindle operation, coolant flow, and tool changes. Once the CNC machine receives these codes, it moves and rapidly rotates the cutting tool according to the instructions, removing material at the correct locations until the part is fully machined.
Why choose CNC machining?
CNC machining offers a series of decisive advantages, making it the preferred method for precision parts manufacturing: it consistently achieves micron level tolerances (±0.005 mm or better) in both single prototypes and production runs, ensuring every part fully meets your specifications. It provides the capability to machine complex geometries and supports rapid prototyping through to low volume production, thereby shortening lead times and reducing labor costs. Additionally, CNC machining is compatible with a wide range of materials—including aluminum, copper, titanium, and plastic composites—which explains its widespread popularity.
What materials can be used with CNC machining?
CNC machining is compatible with a wide range of materials—including aluminum, copper, stainless steel, titanium, as well as various engineering plastics and composites. For a comprehensive list of available materials or to discuss your specific requirements, please feel free to contact us.
What’s the cost of your CNC machining parts?
CNC machining costs are primarily driven by material expenses, machining time, order quantity, and process complexity. For an accurate cost assessment, please provide your CAD drawings, PDF files, or 3D models, and we will deliver a detailed manufacturing analysis report and quotation within a few hours.
