Introduction To 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 is one of the most widely used machining processes due to the following advantages:

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.

  • 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.

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.

  • 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.

  • 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.

As a professional CNC milling parts manufacturer, YIJIN Hardware has adopted a comprehensive quality control system to ensure your part quality, from communication to production and inspection.

  • Effective Communication: YIJIN Hardware always listens to your needs and requirements through prior communication and discussion, offering you professional suggestions in terms of milling part design, material selection, production procedures, etc.
  • Manufacturing Feasibility Analysis: DFM will be conducted once the order is confirmed. Any possible issues or risks will be raised and reviewed at this stage to make sure you get the best quality CNC milled parts.
  • Strict Quality Control: You will learn the real-time manufacturing process, and a comprehensive inspection report is available upon request before shipment. Any quality issues that occur during the CNC milling process will be resolved immediately.
  • Professional & Experienced Team: With more than 20 years of experience in manufacturing CNC milling parts, YIJIN Hardware is able to provide you with the best CNC parts machining services in the industry.
  • State-of-the-Art Machinery: YIJIN Hardware is equipped with the most advanced CNC milling machines imported from Germany and Japan.

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.

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.

CNC machining is overall a cost-effective way to make custom parts with high precision and accuracy, and the actual price can vary greatly depending on the design, materials, surface finishes, etc.
