What is CNC Milling

CNC milling refers to a process of fixing a blank and then using a high-speed rotating milling cutter to cut the blank so as to get the required shapes and features. When you use the right CNC machining parts, it is possible to perform complicated three-dimensional cutting jobs. This can be done by using a single set of commands and prompts. CNC actually stands for Computer Numerical Control and this takes into account the limitations that exist as far as manual control is concerned.

The milling and boring center can perform three-axis or multi-axis milling and bore for molds, inspection tools, tire tools, thin-walled complex curved surfaces, artificial prostheses, and blades.

When choosing the content of CNC milling, the advantages and key functions of the CNC milling machine should be brought into full play. Five-axis CNC milling is a type of milling.

Industrial Applications of CNC Milling
  • Medical – CNC milling is used to manufacture parts used in the hygiene and medical sectors, such as orthopaedic implants and surgical instruments.
  • Electronics – Electronic hardware, housings, metal laths, panels, engravings, and other electronic parts are made with milling machines.
  • Military – Three- and five-axis machines are used to produce CNC milled parts for aircraft, vehicles, weapons.
  • Aerospace – Aircraft components require CNC milling services to manufacture aircraft engines, transmissions, hydraulic manifolds, landing gear, electrical connectors, housings and more.
  • Automotive – Automotive custom components, including engines, battery boxes and interiors, require CNC-milled components.
  • Food – CNC milling technology is designed for components in food processing machinery, blenders, grinders, shredders, cleaning equipment, and more.
  • Machines – Parts required by the machine tool industry, such as fasteners, fittings, shafts, hydraulics and machine components, are designed using CNC milling technology.
What is the Difference Between Three-Axis, Four-Axis and Five-Axis Machining of CNC Milling

Three-axis – This is one of the most widely used techniques for oem CNC machining parts. A standard CNC milling machine has three axes, and the cutting tool moves along the X, Y, and Z axes to mill the part.
Three-axis machining can be used for various tasks such as drilling, contouring and slotting. This kind of milling machine is relatively simple, and generally refers to three axes that move linearly in different directions, such as up and down, front and rear, and left and right. Three axes can only machine one surface at a time, and the most effective machining surface is only the top surface of the workpiece.

Four Axis – We use this milling machine to make more complex parts. It incorporates an additional motion profile through rotation on the vertical axis, allowing for greater flexibility and introducing more continuous machining.
Four-axis milling involves the same process as three-axis machining, however, the milling is performed on an additional axis. A four-axis CNC machine operates on the X, Y, and Z axes, and also includes rotation around the X axis, which is called the A axis.

Five Axis – These machines are the most advanced and widely used type of CNC milling machine. A five-axis milling machine combines three conventional axes with two additional degrees of motion. It operates by increasing the rotation of the table and spindle.
With this milling machine, we can machine 5 sides of the workpiece with one machine without having to do multiple setups.
Five-axis milling machines are the best on the market right now. It can create precise and complex parts for aerospace products, CNC milling turning parts, automotive mechanical components, medical products, precision CNC milling parts, mold making, and more. This machine is ideal for your project as it offers the option of single-step machining, reducing production time. It also makes complex geometries easier to access and increases tool life.

How Does YIJIN Hardware Ensure the Quality of the Parts?

YIJIN Hardware will proactively understand the quality points that customers care about from the initial communication, and provide cost-effective and rationalized suggestions from design, material, production process, manufacturability, etc.

Once your order is confirmed, we will conduct a full Manufacturing Feasibility Analysis (DFM) review for you to raise any issues we believe may affect the quality of your CNC turning milling parts.

We will share the order manufacturing process with you in real time and resolve any quality issues that may be encountered during the production process. All incoming materials will meet your design specifications, and a comprehensive inspection report can be provided for confirmation before shipment.

What Kind of Precision Can CNC Machining Achieve?

The final tolerance of a part depends on many factors, including but not limited to: part size, design geometry, material, surface finish, etc., so no given tolerance range applies to different types of parts.

Normally, we can guarantee the machining accuracy of ± 0.10mm to ± 0.05mm, and adopt the international standard ISO 2768 to control the unmarked linear tolerance of machined parts.

If there are tighter tolerance requirements, our engineering team will communicate with you further.

Do You Provide OQC Report? Such as Material Certificate and FAQ?

We can provide OQC report according to customer’s specific requirements. If the customer needs, we can also provide additional material reports, inspection reports, compliance certificates, etc.

This information requires customers to confirm clearly before placing an order, otherwise it will be difficult to temporarily provide information such as material reports.

Can YIJIN Hardware as A Custom CNC Milling Parts Manufacturer Guarantee the Quality of Your Custom CNC Milling Parts?

Sure. As a top custom custom machining parts manufacturer, Yijin Hardware has been dedicated to custom CNC turning milling parts for more than 20 years, with high precision CNC milling equipment imported from Germany and Japan.
