Principles and Types of CNC Machining Technology
CNC machining is an automated manufacturing process that uses computer programs to control the movement of machine tools, precisely performing operations such as cutting, drilling, and milling on workpieces according to preset instructions. Its core lies in “Computer Numerical Control,” meaning all machining parameters, such as tool paths, feed rates, and spindle speeds, are controlled by computer programs, replacing the tediousness and uncertainty of traditional manual operations.
| CNC Machining Type | Technical Principle | Application Advantage |
|---|---|---|
| CNC Lathe Machining | The workpiece rotates at high speed while the cutting tool, fixed on a tool holder, cuts the workpiece along a preset path. | Primarily used for processing rotationally symmetrical workpieces. |
| CNC Milling Machining | Unlike lathe machining, it uses a rotating milling cutter to cut a stationary workpiece[cite: 48]. The cutter moves along multiple axes, enabling complex operations such as surface and curved surface machining. | Provides a significant advantage in manufacturing parts with complex shapes. |
| CNC Turn-Milling Machining | An advanced technology that integrates turning and milling functions into a single machine tool. | Allows for multiple complex machining operations to be completed in a single clamping, significantly improving efficiency and accuracy. |
Diverse Application Cases of CNC Machining
Due to its high precision and efficiency, CNC machining technology has been widely applied in various industries, from daily necessities to high-tech products.
| Application Industry | Application Cases |
|---|---|
| Automotive and Motorcycle Industry | Used to produce various precision parts, such as engine components, transmission system parts, and braking system parts. CNC machining ensures these parts meet strict standards for high precision and reliability. |
| Aerospace Industry | Used to manufacture complex and high-precision parts such as aircraft engine blades, fuselage structural components, and missile components. These parts typically use lightweight, high-strength special alloy materials. |
| Medical Device Industry | Plays a key role in manufacturing surgical instruments, implants (such as artificial joints, dental implants), and medical equipment components. |
| Electronics and Semiconductor Industry | Used to manufacture precision components in mobile phone casings, connectors, heat dissipation modules, and semiconductor equipment. This meets the precision requirements of product miniaturization and high performance. |
