CNC milling and turning services can be combined to provide the most optimal machining solutions based on the shape and functional requirements of the parts.
CNC Milling
CNC milling of prototype CNC machining is a process that utilizes computerized controls to manage the movement and operation of multi-point rotary cutting tools. As the tools rotate and move across the surface of the workpiece, they slowly remove excess material to achieve the desired shape and size. Standard CNC machines include 3-axis, 4-axis, and 5-axis milling machines. Multi-axis metal CNC machines require no fixed tooling, are highly flexible, and extremely accurate.
CNC Turning
CNC turning is the ideal way to make deep holes, machined threads, and all types of cylindrical shapes that have superior surface finishes. Turning is available for products including dial plate drums, rings, shafts, segments & castings. Milling & boring services are also available. When you need precisely manufactured parts, fast turnaround, and no volume limitations. CNC turning at Top Prototype is your best solution

Our CNC machining service is applicable to various materials from metals to plastics. Please take a look at the CNC Produces machining material list. You are also welcome to contact us to discuss your personal needs.
| Materials | Description | |
|---|---|---|
 | Aluminum | Aluminum has an excellent strength-to-weight ratio among these metals. This is an excellent choice for high load requirements on aircraft mounts and enclosures. Aluminum also has good ductility, stiffness, corrosion resistance and workability. Its lightweight properties make it useful in aerospace structural applications such as fuselage skins, wing ribs, wing skins, etc. |
 | Copper | Copper has excellent thermal conductivity, electrical conductivity and plasticity. It is also highly ductile, corrosion resistant and easy to weld. |
 | Stainless steel | Stainless steel is a type of mild steel whose properties are sought after in many industrial applications. Stainless steel usually contains at least 10% chromium by weight. They are the first choice for critical joints in engine and exhaust components, landing gear components and aircraft superstructures, ensuring high performance and durability. |
| Titanium | Titanium has many material properties that make it an ideal metal for demanding applications. These properties include excellent resistance to corrosion, chemicals and extreme temperatures. This metal also has an excellent strength-to-weight ratio. |
 | Plastic | Plastic is also a very popular choice for CNC machining because of its wide selection, relatively low prices, and significantly faster machining times. We offer CNC machining services for all common plastics. |
CNC Machining Surface Treatment
Surfacing finishing techniques of CNC machining prototype service both functional and aesthetic purposes. Each technique has requirements, such as materials, color, texture, and price. Below are the surfacing finishing technique rendered by us.
| Process | Description | |
|---|---|---|
| Sandblasting | After sandblasting treatment, the surface of the parts has a matte texture. It is mainly used for visual applications and can then undergo other surface treatments. |
 | Anodizing | Anodizing improves corrosion resistance, enhances wear resistance and hardness, and protects metal surfaces. Widely used in mechanical parts, precision instruments, aircraft, automobile parts, etc. |
 | Electrostatic spraying | Electrostatic spraying is a coating applied as a free-flowing dry powder. Unlike traditional liquid coatings, which are delivered by evaporating solvents, powder coatings are typically applied electrostatically and then cured under heat or UV light |
| Polishing | The polishing range spans from Ra 0.8 to Ra 0.1. The polishing technique utilizes abrasive materials to rub against the surface of the parts, leading to the surface of the parts becoming either more lustrous or less lustrous, all depending on your requirements. |
| Plating | The electroplating coating enables the reduction and deposition of metal cations by applying an electric current, which can protect the surface of the parts and prevent corrosion caused by rust and other defects. |

FAQ
CNC machining refers to the machining process proceed by Computerized Numberical Control (CNC for short).It’s a manufacturing process which involves the use of automated rotating cutting tools and lathes to make custom designed metal and plastic parts. Our CNC machines precisely remove material from solid metal or plastic blocks to develop custom parts that can range from simple lines to complex shapes. With this manufacturing process we can develop custom machine parts, prototypes and tooling such as subplates, rotary fixtures, automotive and aerospace fixtures.
Also called precision machining, the CNC machining could reach a very high accuracy in geometical tolerance and dimensional tolerance. With our CNC machines and Horizontal Machining Centers (HMC) and Vertical Machining Centers (VMC), we can almost meet all of your required tolerance grades.
We work with many types of Stainless Steels, Aluminums ,metals and plastics (i.e. Teflon, Delrin, Acetal) and many more.
For CNC machining components, we can have them as machined, de-burred, sanded, polished, painted, silk screened, electroplated, anodized, etc. It all depends on your needs.
