What Is CNC machining?

CNC machining (Computer Numerical Control machining) is an advanced manufacturing process that controls precision machine tools through digital programs to shape materials such as metals and plastics by cutting. It is the preferred processing technology for core components in fields such as aerospace, automotive, and medical.
The main CNC machining services include:

CNC Milling

CNC Machining Applications

There are many ways that CNC Machining can be appalled in the commercial and domestic space. Some of the notable applications include the following.

Tooling & Mold Manufacturing:

In addition to end-use components, CNC machining is widely used in tooling and mold manufacturing. We machine high-precision mold cores, cavities, inserts, and mold components where tight tolerances, surface quality, and dimensional stability are critical for reliable injection molding production.

Rapid prototyping:

Prototyping is the process where experimental models are made to address a certain problem. Usually, this prototype CNC machining requires a lot of time, but thanks to advanced technologies and machines, rapid prototyping is now possible. The process can be applied in creating car parts and home appliance components in huge numbers.

Surface Finishing:

Appearances are everything, and CNC machining can be used to convert a flat-looking surface into a beautiful finish. This comes in handy when dealing with automobiles, home appliances, among many other daily use products.

Core Advantages of CNC Machining

Ultra-high precision control01

The positioning accuracy reaches ±0.005mm, and the surface roughness is within Ra0.8μm Five-axis linkage can achieve an angle precision of 0.01° (such as in the processing of impeller blades)

Complex structure forming capability02

Supports features such as deep cavities, micro-holes (minimum Ø0.1mm), and irregular curved surfaces. The car milling combined process enables "the completion of all processes in one setup"

Wide material adaptability03

Metal: Aluminum alloy/Titanium alloy/Hot-rolled nickel-based alloy (hardness ≤ 60HRC) Non-metal: Engineering plastics/Composite materials/Ceramics (Special tools are required)

Batch consistency guarantee04

CV value (dimensional variation coefficient) < 0.5% The automated production line can achieve 24-hour continuous processing.

Advantages of Digital Production05

CAD/CAM seamlessly integrated, rapid model change (within 30 minutes) Internet of Things (IoT) for real-time monitoring of tool wear, temperature and vibration
