What is CNC Milling?
CNC milling is a subtractive manufacturing process in which computer-controlled cutting tools progressively remove material from a workpiece in order to create a desired shape or object. This process is achieved using machines known as CNC milling machines or CNC mills. It is the most widely-used of the mechanical machining processes, others being CNC turning.
CNC milling is just one of the CNC machining processes available. Milling is a particular form of precision CNC machining. Milling uses a cutter that removes material by moving into the workpiece at an angle. The movement of the cutter is controlled by computer instructions, allowing for extreme precision and repeatability.
How Does CNC Milling Work?
CNC milling starts by fixturing a block of metal or plastic material inside the CNC mill. Using G-code, the CNC machine is programmed to rapidly mill out parts from the block of raw material. Our 3- and 5-axis CNC machines are equipped with various toolsets to maximize efficiency and production speed.
Machined plastic parts are left as-milled, which typically means they show visible tool marks. Some metal parts allow more finishing choices like anodizing and chromate plating. When the run is complete and your required surface finish is applied, parts are boxed and shipped shortly thereafter.
CNC Milling Machines
Vertical Machining Centre (VMC) – The spindle in a VMC remains in one position and the table moves underneath it. In some cases the table moves up to meet the spindle or the spindle can move up and down on the Z-axis. These machines are very rigid and can therefore produce highly precise components. They have the disadvantage of a relatively small work area. VMCs can have 3 axes (X, Y, Z), 4 axes (X, Y, Z & A) or even 5 axes (X, Y, Z, A & B).
Horizontal Machining Centre (HMC) – An HMC is a machine whose spindle is oriented horizontally instead of vertically. These types of machines are ideal for long production runs as they can machine up to 3 times as much as a VMC, provided there is enough work to keep the machine busy. An HMC is also much more expensive than a VMC. A block of material can be fixtured on the bed of the machine while another part is being manufactured. This is why continuous production is possible, as the spindle can easily move to the next block of material that is ready and change out is very quick.

Based on customer’s design, our CNC milling machines can usually reach tolerances of ±0.01 mm and even low to ±0.005 mm. Our standard tolerances for CNC milled metals is ISO 2768-m and ISO 2768-c for plastics. Our basic guidelines for CNC milling include important design considerations to help improve part manufacturability, enhance cosmetic appearance, and reduce overall production time and costs.
| Type | Min Milling Tolerance |
|---|---|
| Linear dimension | +/- 0.005 mm (+/- 0.0002 inch) |
| Hole diameters (not reamed) | +/- 0.005 mm (+/- 0.0002 inch) |

CNC Milling Materials
Our CNC milling processes are compatible with a wide range of materials, including machine-grade metals and plastics. Depending on your applications, we can create precise rapid prototypes and low-volume production from various superior-quality materials. Check out some of the common materials for your CNC milling projects.
Aluminum Milled Part
Aluminum is a highly ductile metal, making it easy to machine. The material has a good strength-to-weight ratio and is available in many types for a range of applications.
Brass Milled Part
Brass has desirable properties for a number of applications. It is low friction, has excellent electrical conductivity and has a golden (brass) appearance.
Copper Milled Part
Copper displays excellent thermal conductivity, electrical conductivity and plasticity. It is also highly ductile, corrosion resistant and can be easily welded.
Stainless Steel Milled Part
Stainless steel is the low carbon steel that offers many properties that are sought after for industrial applications. Stainless steel typically contains a minimum of 10% chromium by weight.
Titanium Milled Part
Titanium has a number of material properties that make it the ideal metal for demanding applications. These properties include excellent resistance to corrosion, chemicals and extreme temperatures. The metal also has an excellent strength-to-weight ratio.
Plastic Milled Part
Plastics are also very popular option for CNC machining because of its wide choices, relatively lower price, and significantly faster machining time needed. We provide all common plastics for CNC machining services.
POM / PEEK / HDPE / PET / Nylon / PTFE / PVC / PP / ABS / PC / PMMA
CNC Milling Surface Finishes
We break the edges on all machined parts. All machined plastic parts are left as-machined, which may leave visible tool marks. Some metal parts, on the other hand, allow more choice. Parts left with sharp edges should be handled with care.
Gain access to quality surface finishing for custom CNC milled parts to remove aesthetic flaws and improve the appearance of your products. We also provide rigid protection and additional resistance and strength to your parts through superior surface finishes.
| Type | Description | Material | 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 |
| 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, Carbon Steel | Black, any Pantone number | Gloss or semi-gloss |
| Abrasive Blasting | Abrasive 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, Stainless Steel, Carbon Steel | n/a | Matte |
| 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, Carbon Steel, Stainless Steel | n/a | Smooth, glossy finish |
| 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, Carbon Steel | n/a | Satin |
| 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, Carbon Steel | n/a | Glossy |
| Painting | Painting involves spraying a layer of paint onto the surface of the part. Colors can be matched to a Pantone color number of the customer’s choosing, while finishes range from matte to gloss to metallic. | Aluminum, Stainless Steel, Carbon Steel | Custom | Gloss, semi-gloss, flat, metallic, textured |

We can produce highly complex and intricate rapid prototypes and low-volume production parts. The CNC milling process is suitable for a wide selection of materials for various applications. Our CNC milling service can achieve standard tolerances of up to +/- 0.01mm.
We work with vertical, horizontal, and multi-axis milling machines. The vertical milling machine is highly accurate equipment that carries out 3-axis milling, suitable for vertical surfaces and angular shapes.
Our horizontal milling machines perform 4-axis milling and are suitable for heavy milling operations. Our multi-axis milling machines can move along different axes and cut at various angles. They include 2-, 3-, 4-, and 5-axis CNC milling machines.
The major difference between CNC milling and CNC turning is in their machining process. CNC milling involves rotating the cutting tools against a stationary bar stock or workpiece. In contrast, CNC turning works by rotating the bar stock or workpiece against a stationary tool. CNC milling is more suitable for machining irregular and flat surfaces, while CNC turning work best for cylindrical or conical parts.
CNC milling is one of the most popular custom CNC machining processes. CNC milling services are used for the majority of machined parts because it can handle a wide variety of irregular geometries. It is also an efficient means of mass production once the setup is complete.
Yes. We can use a CNC machine to mill details onto parts made through other processes like turning and casting.
