3 Axis CNC Milling

With 3-axis CNC milling, the cutting tool can create flat surfaces, pockets, slots, and other shapes in the material being machined. It is commonly used in industries such as aerospace, automotive, and medical to produce parts with high precision and accuracy.

4 Axis CNC Milling

The rotary axis can be used to rotate the material being machined or the cutting tool itself, which allows for more complex shapes and designs to be created. For example, a 4-axis CNC milling machine can create curved surfaces, helixes, and spiral shapes that would be difficult or impossible to make using a 3-axis machine.

Surface Finishes for CNC Milling parts

CNC Milling leaves visible tool marks during the process of removing portions of the block’s surface to create desired shapes. If don’t want as-machined parts, select a surface finishing for your custom parts. At Machcncmaster, we offer several common surface finishes that help improve functionality and aesthetics.

Anodizing
Bead Blasting
Powder Coating
Electroplating
Polishing
Brushing

Advantages of CNC milling

CNC milling offers several advantages over traditional manual milling methods.

Increased Precision and Accuracy

CNC milling machines are capable of producing parts with very high precision and accuracy, which is critical in industries such as aerospace, medical and automotive. A computer control system ensures that the cutting tool follows the programmed path exactly, resulting in consistent and accurate parts.

Flexibility and Versatility

CNC milling machines can be programmed to produce a wide range of parts, from simple to complex designs. This flexibility allows manufacturers to produce custom parts to meet specific requirements.

Making angled shapes

CNC milling is an ideal choice for manufacturing angled shapes, planes, grooves and channels, holes, curves, chamfers, and many other features.

Cost savings

While CNC mills are expensive to purchase and maintain, significant savings can be realized over time. Increased efficiency and precision can reduce waste and scrap, while the ability to produce complex parts can eliminate the need for multiple machines or additional processing steps.

Frequently Asked Questions

The major difference between CNC milling and CNC lathe is in their machining process. CNC milling involves rotating the cutting tools against a stationary bar stock or workpiece. In contrast, a CNC lather 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 lathes work best for cylindrical or conical parts.

CNC milling starts with designing a digital part with CAD software. Then the file will be converted into CNC readable program code, which can be recognized by a CNC mill and dictates to the mill how to rapidly fabricate parts from raw material blocks.

Different from CNC lathes or turning centers where a stationary cutting tool removes material by making contact with the spinning workpiece, CNC mills cut away block or bar stock by a rapidly rotating cutting tool moving against the workpiece. The tool path is controlled by computer instructions, enabling improved reliability and repeatability regardless of potential human error.

With its high flexibility and capacity of manufacturing almost all types of irregular geometries and complex parts, CNC milling has become one of the most popular methods for both rapid prototyping and end-use production.

At Machcncmaster, our automatic tool changers can encompass drilling, boring, counter boring, counter sinking, profiling, cutting, reaming, threading, tapping, and other operations completed in the same setup. We can produce almost any shape of CNC components with various tooling and ingenuity in professional milling centers. Parts’ dimensions and features decide the selection of multiple-axis machines. And a single setup will ensure the accuracy and quality of components with complex geometry. Multi-axis milling needs complex, skillful, and meticulous programming, so a precision 3D CAD file will reduce our quoting and programming time. Elements such as tolerance, surface finishes, part size, tooling, and material properties will affect the quotation directly. Now upload your CAD file, and get a quote from Machcncmaster.

Different milling types can achieve different functions and can be suitable for different applications. Usually, CNC milling services can be divided into the main 8 types of operations:
