What is CNC Milling & Why CNC Milling

CNC milling parts are produced by rotating the cutting tools to remove material from the workpiece while the workpiece itself remains stationary.

CNC milling service is one of the most widely used machining processes due to the following advantages:

  • Almost all engineering plastics, metals, and composites can be processed via CNC milling services.
  • CNC-milled parts come with high precision, accuracy and tolerance.
  • Precision CNC milling service is able to handle parts with complex geometric shapes.
  • CNC milling can be applied to shape parts from beginning to finish.
  • 3-, 4-, and 5-axis CNC milling offers flexibility in processing to create complex parts.
  • CNC milling is highly efficient and multiple surfaces can be processed in one go.
  • 24-hour continuous operation with improved efficiency and intelligent automation.

What is CNC Milling Service & How Does It Work

What does CNC machining stand for? CNC is shortened form of Computerized Numerical Control. In short, the CNC milling service basically involves the machining process that uses a rotating tool to remove the material of a workpiece until the desired shape is achieved.

How does CNC milling work? During the process, the raw materials are fixed in place on a CNC worktable which can move on different planes and axes (up to 5 axes, typically in X, Y, and Z axes) so the cutting tool can work at multiple angles. The rotating tool spindle at a very high speed to cut the material and achieve the desired finished part.

CNC machining is one of the most common and basic mechanical manufacturing processes due to its high accuracy, precision and tight tolerance (down to +-0.001mm) for creating complex specifications of your custom parts.

The best part of precision CNC milling service is its capability to produce complex shapes and precision parts with tight tolerance throughout the process, whether in small or large batches.

Features of CNC Milling
  • Great versatility. CNC milling is known for its flexibility and versatility in processing various parts with different structures and shapes. It can complete various operations including drilling, boring, plane milling, end-face milling, tapping, etc.
  • High precision. CNC-milled parts are highly accurate without any operating errors by the operators, which ensures dimensional identity all the time and improves product quality.
  • High efficiency. CNC milling machine combines the functions of a milling machine, boring machine and drilling machine, offering a centralized procedure with much higher production efficiency and fewer clamping errors.
  • Part Complexity. CNC milling can handle complex profiles that are impossible for CNC lathes. Thanks to its multiple feed coordinates, CNC milling can deal with plane curve contours and spatial surface contours.
What's the Difference between 3-Axis, 4-Axis, and 5-Axis CNC Machining?

The number of axes implies the complexity of the movements of the workpiece and cutting tool compared to each other. Simply put, 5-axis machines can produce CNC mill parts with more complex geometry compared with the others.

  • 3-axis is one of the most simple and widely used techniques for CNC machining parts. With a standard 3-axis CNC machine, the cutting tool moves along the X, Y, and Z linear directions.

3-axis

  • 4-axis CNC machine incorporates one additional rotation around the X-axis in the horizontal plane (known as A-axis) which occurs to the workpiece itself, allowing for greater flexibility and more complexity in design.

4 axises

  • 5-axis is the most advanced type of CNC milling machine. It has two additional rotation axes (A/B axis and C axis) compared with the 3-axis ones. The rotation can occur to either the table or the spindle.

  • State-of-the-Art Machinery: YIJIN Hardware is equipped with the most advanced CNC milling machines imported from Germany and Japan.
What tolerance can CNC milling parts achieve?

The tolerance of CNC-milled parts depends on many factors, including (but not limited to) part sizes, the complexity of your design, materials, and surface finishes. There is no specific number that suits all types of design.

At YIJIN Hardware, our standard tolerances for CNC-milled parts range from ± 0.10mm to ± 0.05mm. For the unmarked linear tolerance of CNC machined parts, we comply with the standard of ISO 2768.

A tighter tolerance is also possible for your custom-milled parts. Send us a message and discuss the customized CNC service required with our engineers.

Can You Provide an OQC Report (or Material Certificate, FAQ, etc)?

Yes, we can provide the OQC report (and material report, inspection report, compliance certificates, etc) upon your request. Please make sure to ask for it before you place/confirm the order.

Otherwise, we may not be able to provide some of the required information, such as material reports.
