What Is the Process of CNC Milling Parts?

100

Numerically controlled (CNC) milled parts are precision components processed through CNC milling machines. They combine the precision of CNC technology with the flexibility of milling processes, enabling the manufacture of high-precision, complex-shaped parts. By using CNC milling machines, the movement trajectory of the tool on the workpiece and the cutting parameters are controlled through programming, resulting in a precision part. These parts are widely used in aerospace, automotive, racing, electronics, medical equipment, and other fields, where high precision and quality are required. MQJM are CNC milling parts manufacturers, adhering to the business philosophy of "customer first",  and is committed to providing customers with more product choices.


Characteristics of CNC Milling Parts


High Precision


CNC milling parts can achieve very high processing accuracy, meeting the needs for parts with strict dimensional and geometric requirements. Through precise programming and advanced CNC systems, the parts produced can ensure extremely high dimensional and shape accuracy.


High Efficiency


CNC milling machines are highly automated and have fast processing speeds, significantly improving production efficiency. By optimizing cutting parameters and tool paths, the processing cycle can be further shortened, reducing production costs.


Flexibility


CNC milling parts are suitable for processing various structures and shapes, including curves, concave and convex surfaces, multi-hole structures, and other complex shapes. Different shapes and sizes of parts can be easily achieved through programming control.


Repeatability


CNC milling parts have extremely high repeatability, ensuring that parts produced in batch quantities are consistent and accurate. This is particularly important for industries requiring mass production of high-precision parts.


Processing Flow of CNC Milling Parts


Programming


According to the part drawing and requirements, use CAD/CAM software for programming to determine the movement trajectory of the tool and cutting parameters.


Clamping the Workpiece


Place the workpiece on the CNC milling machine's workbench and clamp it securely to ensure the workpiece does not move or deform during processing.


Tool Alignment


Use a tool setup instrument or trial cutting method to determine the relative position between the tool and the workpiece, ensuring the tool can accurately cut the workpiece.


Start Processing


Start the CNC milling machine and process according to the preset program. During processing, the CNC system automatically controls the movement trajectory of the tool and the cutting parameters, completing the milling process of the workpiece.


Inspection and Correction


After processing is completed, inspect the part to check if its dimensions, shape, and surface quality meet the requirements. If necessary, make corrections and adjustments.
