CNC Machining Processes
CNC Milling
CNC milling is a subtractive process that uses 3-, 4-, and 5-axis milling machines and a variety of cutting tools to remove material from solid blocks of plastic and metal into final parts with varying geometries. With our 3-axis and 5-axis CNC milling services, you will be able to get milled parts with a tolerance of 0. 01mm.
CNC Turning
CNC turning is the process of cutting metal or plastic parts with cylindrical features from the outside of a bar with a rotating tool. The turning process can effectively manufacture circular parts and can be applied to create parts with complex internal and external geometries and various threads.
CNC Machining Tolerances and Standards
With precision CNC machining services, NOBLE is your ideal partner to create precision machined prototypes and parts. Our standard CNC machining tolerances for metals is ISO 2768-f and for plastics is ISO 2768-m. We can also achieve special tolerances as long as you indicate your requirements for your drawing.

Surface Finishes for CNC Machining
CNC machining leaves visible tool marks during the process of removing portions of the block's surface to create desired shapes. If you don't want as-machined parts, select a surface finishing for your custom parts. At NOBLE, we offer several common surface finishes that help improve functionality and aesthetics.
| Name | Description | Materials | Color | Texture | |
 | Anodizing | Anodizing improves corrosion resistance, enhancing wear resistance and hardness, and protecting the metal surface. Widely used in mechanical parts, aircraft, and automobile parts, precision instruments, etc. | Aluminum | Clear, black, grey, red, blue, gold. | Smooth, matte finish |
 | Sand Blasting | Sand blasting results in parts with a smooth surface with a matte texture. Used mainly for visual applications and can be followed by other surface treatments. | ABS, Aluminum, Brass | N/A | Matte |
 | Powder Coating | Powder coating is a type of coating that is applied as a free-flowing, dry powder. Unlike conventional liquid paint which is delivered via an evaporating solvent, powder coating is typically applied electrostatically and then cured under heat or with ultraviolet light. | Aluminum, Stainless Steel, Steel | Black, any RAL code or Pantone number | Gloss or semi-gloss |
 | Electroplating | Electroplating can be functional, decorative or corrosion-related. Many industries use the process, including the automotive sector, in which chrome-plating of steel automobile parts is common. | Aluminum, steel, Stainless Steel | N/A | Smooth, Glossy finish |
 | Polishing | Polishing is the process of creating a smooth and shiny surface, either through physical rubbing of the part or by chemical interference. The process produces a surface with significant specular reflection, but in some materials is able to reduce diffuse reflection. | Aluminum, Brass, Stainless Steel, Steel | N/A | Glossy |
 | Brushing | Brushing is a surface treatment process in which abrasive belts are used to draw traces on the surface of a material, usually for aesthetic purposes. | ABS, Aluminum, Brass, Stainless Steel, Steel | N/A | Satin |

Devin W --- Vice President
I worked with another Chinese machine shop for eight years, and while the relationship was initially great, I eventually became disappointed by quality issues, late delivery, and a complete lack of communication.So I decided to give NOBLE a chance with a small order.Not only did they deliver on schedule, but they also did it with 100% accuracy and attention to detail.It was the same with my next order.They have exceeded all my expectations: they are a pleasure to work with; they respond to my inquiries by the next day (often within hours) and do whatever it takes to meet my requirements.This is what working with a machine shop should be like.

CNC Machining FAQs
- Q
What is CNC machining?
ACNC 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.
- Q
What are the advantages of CNC machining?
AThe main advantages of CNC machining over traditional methods are greater accuracy, more precise control, and higher efficiency. Precision-turned components milled by CNC machines are of higher quality than those from manually operated machines.
- Q
What's your CNC machining capacity?
AWe can serve more than 10000 different prototypes every month, no matter if it is a simple or complex design. We are equipped with a clean assembly workshop of 1000m², have 100 CNC machine tools, and have established more than 30 experienced technical teams and a more complete laboratory.
- Q
Why choose CNC machining?
ACNC machining is a fast, accurate and versatile solution for making end-use plastic and metal parts in any quantity, without the need for investing in hard tooling or expensive set-ups. No matter how simple or complex the parts.
- Q
What materials can be used with CNC machining?
AThere's a wide range of materials that can be used in CNC machining – you can use such as aluminum, steel, brass, copper, titanium, as well as rigid plastics. Reach out to learn more about the types of materials that could be used.
- Q
How can I reduce the cost of my machined parts?
AThe main costs associated with CNC machining can be grouped into machining time, start-up costs, material costs, and feature costs. To reduce costs you need to understand the impact of these factors on cost.
1. The best way to reduce machining time is to design features that can be machined quickly, for instance, choosing the correct radii for internal corners, reducing cavity depth, increasing wall thicknesses, limiting thread length, and designing holes with standard sizes.
2. Material costs can be reduced by considering the size of the blank required, and the cost and machinability of the bulk material (softer alloys are faster to machine).
3. Start-up costs can be reduced by reducing the number of part rotations or repositioning required to finish the part, for example, separating geometries into multiple parts that can be assembled later.
4. Feature costs can be reduced by only using tolerances when strictly necessary, removing all text & lettering, and avoiding multiple surface finishes.
- Q
How do you guarantee the machining quality of my parts?
AOur sound quality-control system makes sense that thousands of customers place their CNC machining orders in our company. The regular check and testing start from incoming materials to shipment, ensuring each part is produced accurately for your specifications.
We possess a comprehensive, standardized inspection report with every order to ensure quality metrics are being met, and offer a first-article inspection service on orders of 100+ units. We also have multiple certifications available on request, including but not limited to ISO9001 and ISO13485.
- Q
What kind of a finish does CNC machining leave?
ADue to the spinning motion produced by the CNC milling machine's cutter, the surface finish of CNC machined parts will have visible tool marks. If you require a smooth, unblemished finish for your parts, we recommend choosing a secondary finish: grained finish (can only be applied to the outside of machined enclosures due to geometry) or powder coat.
- Q
What industries use CNC machining?
ACNC machining is widely used across a wide range of industries. It is common in aerospace, automotive, consumer electronics, robotics, agriculture, and other fields that frequently use metal parts. It is also widely used in medical devices, household goods, energy, oil and gas, and other consumer applications. It is one of the most common processing methods in the manufacturing field.
NOBLE has offered ultra-precision CNC-crafted components for global industries including oil and gas CNC machining, medical instruments CNC machining, optical CNC machining, tool and die parts CNC machining, motorcycle components CNC machining, electronic enclosures CNC machining, automotive parts CNC machining, etc.

ANOBLE can accommodate prototyping and production of large machined parts, plastic or metal. The maximum size of our single piece is 2000mm, and the single-piece proofing can reach hundreds of thousands of batch processing and production.
- Q
What are the tolerances of machined parts?
AWe can provide critical tolerance according to your actual demand. For CNC machining, we manufacture metal parts as per ISO 2768-m and plastic parts as per ISO 2768-c. Please note that the higher tolerance needed, the cost will be higher.
