In the field of modern precision machining, CNC milling (Computer Numerical Control Milling) and CNC turning (Computer Numerical Control Turning) are two extremely important processing methods. For numerous enterprises such as cnc machining parts factory (numerical control machining parts factory), cnc turning factory (numerical control turning factory), and cnc machining company (numerical control machining company), a deep understanding of the differences between the two helps to accurately select the processing technology and meet the diverse needs of different industries. The picture shows CNC turning parts：
Differences in Processing Principles
Processing Principle of CNC milling
CNC milling mainly relies on a rotating milling cutter to cut the workpiece. During the processing, the workpiece is fixed on the workbench, and the milling cutter moves along multiple coordinate axes in a complex manner according to a pre - written program, enabling the processing of various surfaces of the workpiece. For example, when processing complex molds, with a cnc milling machine aluminum (numerical control aluminum milling machine), the milling cutter can precisely move along a complex three - dimensional path, milling out various shapes of grooves, protrusions, and contours on the workpiece, meeting the processing requirements of parts that need multi - surface and multi - angle processing in industries such as auto parts mold manufacturing (automotive parts mold manufacturing). Many enterprises engaged in cnc machining for medical devices (numerical control machining for medical devices) and cnc machining for car parts (numerical control machining for automotive parts) often use CNC milling technology to manufacture products with variable shapes and high - precision requirements, such as the fine components of medical surgical instruments and the complex oil passage channels on automotive engine blocks. The picture shows CNC Milling parts:
Processing Principle of CNC turning
CNC turning is carried out by the rotation of the workpiece in cooperation with the linear movement of the cutting tool. The cutting tool is fixed on the tool holder, and the workpiece is clamped on the chuck and rotates at high speed. The cutting tool moves along a direction parallel or perpendicular to the axis of the workpiece, thereby processing the outer circle, inner hole, thread, and other parts of the workpiece. For example, when producing shaft - type parts, a cnc turning factory can use this processing method to quickly and accurately cut out shaft outer diameters, shaft shoulders, inner holes, and other structures that meet the dimensional requirements. In the automotive industry, parts such as automotive drive shafts and half - shafts, as well as some shaft - type parts in semiconductor equipment manufacturing, such as parts of semiconductor equipment (semiconductor equipment parts), are mostly processed using the CNC turning process to ensure key precision indicators such as coaxiality and cylindricity of the parts.

Differences in Equipment Features Equipment Features of CNC milling
CNC milling machines are usually equipped with a multi - axis linkage control system, commonly three - axis, four - axis, or even five - axis linkage. Multi - axis linkage enables the equipment to complete the processing of complex shapes in one clamping, greatly improving processing efficiency and accuracy. At the same time, it has a high - precision transmission system and cutting system, which can ensure the stability and positioning accuracy of the tool during high - speed movement. When processing precision machining parts for other industries (precision machining parts for other industries), such as parts in the aerospace field, multi - axis linkage CNC milling equipment can precisely process parts with complex curved surfaces, meeting the strict requirements of this industry for high - precision and high - performance parts. Many cnc machining manufacturer in china (numerical control machining manufacturers in China) rely on advanced CNC milling equipment to win a good reputation in the international market. The video below is CNC Milling parts: Equipment Features of CNC turning
The core of CNC turning equipment lies in its high - precision rotary spindle and precise tool holder system. The rotary spindle can drive the workpiece to rotate at high speed and stably, ensuring the smoothness of the cutting process. The tool holder system is responsible for the rapid tool change and precise feed of the cutting tool. Compared with CNC milling equipment, CNC turning equipment has higher efficiency and accuracy advantages when processing rotary parts. For example, when producing a large number of shaft - type parts with the same specifications, a cnc turning company can optimize the tool path and cutting parameters and use CNC turning equipment to achieve efficient and stable mass production, providing high - quality shaft - type products for automotive component manufacturers (automotive parts manufacturers) and car part manufacturers (automobile part manufacturers).
Differences in Application Scenarios
Application Scenarios of CNC milling
Since CNC milling can process parts with complex shapes, it is widely used in many industries such as medical, automotive, and semiconductor. In the medical industry, medical cnc machining enterprises use CNC milling technology to manufacture precision medical devices such as artificial joints and dental implants. These products not only require high - precision dimensional control but also have strict requirements for surface quality and complex shapes, and the advantages of CNC milling are fully demonstrated. In the automotive industry, for automotive engine blocks, cylinder heads, and other parts with complex internal structures and external shapes, cnc machining for car parts, cnc machining for auto parts, and cnc machining for automobile parts enterprises usually use the CNC milling process for processing to ensure the performance and quality of the parts. In the semiconductor industry, for Chip test fixtures for semiconductor industry (chip test fixtures for the semiconductor industry), Component test fixtures for semiconductor industry (component test fixtures for the semiconductor industry), and Spare parts for lithography machines (spare parts for lithography machines) and other high - precision and complex - shaped parts, CNC milling technology is also an indispensable processing method.
Application Scenarios of CNC turning
CNC turning is mainly applied to the processing of rotary parts and is widely used in industries such as automotive, machinery manufacturing, and electronics. In the automotive industry, various shaft - type parts of automobiles, such as engine crankshafts and transmission input shafts, are almost all produced by cnc turning factory using the CNC turning process. These shaft - type parts have extremely high requirements for precision indicators such as coaxiality and cylindricity, and CNC turning can meet these strict precision requirements, providing a guarantee for the reliable operation of automobiles. In the machinery manufacturing industry, various drive shafts and lead screws are also mostly processed by CNC turning. In the electronics industry, some small shaft - type parts used in the assembly of electronic products and parts with rotary body characteristics also rely on CNC turning technology.
