CNC Milling

CNC milling is the cutting of solid plastic or metal material into final precision parts using multi-axis milling processes. Unlike CNC lathes, CNC mills remove material from the workpiece by rotating and moving a cutting tool, such as a milling cutter, and positioning the workpiece correctly to produce a finished or semi-finished shape.

Various Material Options

CNC milling is a versatile process that can machine a variety of parts from different materials. It can be used on any rigid material, offering a reliable and efficient solution for a range of manufacturing applications.

High Accuracy

CNC milling machines are capable of removing a significant volume of materials in a rapid and precise manner, while also delivering superior surface finishes.

Rapid Tooling

Milling is a versatile process that is used not only to manufacture finished parts, but also to build molds for plastic injection molding and pressure die casting.

Cost-effective

Milling is highly cost-effective and almost free of waste. This makes it a more cost-effective and waste-efficient option than additive manufacturing.

Time-saving

Due to the extremely short setup time, CAD files can be converted into finished products within a few hours, offering a fast and efficient process. We are pleased to offer you samples that reach you faster.

3 Axis CNC Milling

A 3-axis CNC mill has a tool that can move along the X, Y, and Z axes. Moreover, we are equipped to machine parts with complex geometrical shapes, including undercut features, threaded holes, sharp edges, and planar profiles. Additionally, the automatic tool changer allows for the efficient and integrated completion of multiple operations. Furthermore, we can design 3-axis milling centers to meet each client's specific requirements.

4 Axis CNC Milling

Our 4-axis CNC milling allows you to produce more complex parts with greater precision and accuracy. In addition, even with complex shapes, our technology consistently delivers precise and accurate results, offering greater control and flexibility.Furthermore, with 4-axis milling, you can cost-effectively machine angled features that are challenging to achieve with 3-axis machines. Moreover, our advanced technology provides more power, greater control, and higher precision, making it the ideal solution for your machining needs.

5 Axis CNC Milling

Our 5-axis CNC milling machines enable the production of complex custom parts with a single setup, thus saving time, improving efficiency, and reducing costs. As a result, this allows our clients to meet market demands faster and cost-effectively. Moreover, the machines can reach higher cutting speeds without excessive pressure on the cutter, and furthermore, they produce rapid prototypes and low-volume production parts with better surface finishes.

Applications of CNC Milling

CNC can be applied to virtually any material. Consequently, this makes it ideal for rapid tooling and the creation of fixtures or molds.
CNC is a great option for prototyping because of the range of materials available. Additionally, because of the low unit cost of CNC machining. Moreover, because of the speed of production.

CNC has become the preferred technology for end-use parts because of its high-quality finish. Additionally, it has a wide range of material options. Moreover, it offers precise tolerances.

CNC Milling FAQs

CNC milling is ideal for various features. It can remove material fast and precisely, producing a good finish on any rigid material. Among CNC processes, it’s the most versatile. With minimal set-up time, a CAD file can become a part of hours. No specialty tools are needed, so there’s no minimum order quantity, making it cost-effective with little waste.

Any solid, stable material can be milled. We have a standard selection like hard plastics, aluminum, steels, brass, etc. But some hardened steels may be too hard or need special tools and longer times. Soft elastomer plastics may also be unsuitable as they can’t be held fixed or change shape under tool pressure.

We have experience with various milling machines. Firstly, vertical ones are 3-axis, highly accurate for vertical and angular shapes. Horizontal ones do 4-axis milling for heavy operations. Multi-axis machines can move along different axes and cut at various angles. Specifically, including 2-, 3-, 4-, 5-axis CNC milling machines.

The various milling types are suited to different functions and applications. Typically, CNC milling services can generally be classified into 8 primary operational categories:

Gear Milling/Thread Milling/Plain Milling/Form Milling/Face Milling/Angular Milling/Profile Milling/Straddle Milling

In the precision CNC milling design process, we typically recommend the use of CNC milling for parts requiring intricate details, such as complex planes, curved surfaces, shell parts, connecting rods, propellers, and component housings. However, it is important to note that certain features, such as thin walls, deep cavities, and inner wall cutouts, may not be suitable for CNC milling due to their inherent complexity.

In such cases, we advise consulting with our customer service team for guidance.
