What Is The Difference Between CNC Turning Parts And CNC Milling Machining

CNC turning parts and CNC milling machines play important roles in the field of mechanical machining, and there are significant differences between them. Here is a detailed comparison between the two:
1, Working principle and processing method
CNC turning
Working principle: Control the lathe for automated machining through computer programming. During the machining process, the material rod is held in the chuck and rotated, while the tool is fed into the workpiece to remove the material until the desired shape is achieved.
Processing method: subtractive processing, which involves removing materials to obtain the desired shape.
CNC milling machine processing
Working principle: By receiving the machining program through the CNC system, the movement of each axis of the machine tool and the rotation of the cutting tool are automatically controlled to achieve precise machining of the workpiece.
Processing method: Subtraction processing is also used, but CNC milling machines can perform various milling processes such as flat milling, contour milling, drilling, reaming, boring, tapping, etc.
2, Processing object and scope
CNC turning
Processing object: mainly used for processing various rotating parts, such as shafts, sleeves, disks, etc.
Processing range: Suitable for the production of small and medium-sized parts, especially parts with high precision requirements.
CNC milling machine processing
Processing objects: mainly used for processing various complex shaped parts, such as boxes, brackets, molds, etc.
Processing scope: Widely used in fields such as mechanical manufacturing, aerospace, automotive manufacturing, mold manufacturing, electronic manufacturing, etc.
3, Processing accuracy and efficiency
CNC turning
Processing accuracy: Due to the good rigidity and high manufacturing accuracy of the lathe, it can process parts with high precision.
Processing efficiency: With a high degree of automation, it can significantly improve production efficiency and reduce manual intervention.
CNC milling machine processing
Processing accuracy: Both CNC and servo systems with high precision can achieve high-precision machining.
Processing efficiency: Adopting multi axis linkage and automatic tool changing system can further improve processing efficiency and flexibility.
4, Equipment investment and cost
CNC turning
Equipment investment: relatively high, but in the long run, due to high production efficiency and processing accuracy, it can reduce production costs.
Cost control: By optimizing cutting parameters, selecting appropriate cutting tools and processing methods, production costs can be further reduced.
CNC milling machine processing
Equipment investment: It also has high equipment investment costs, but can also be reduced by improving production efficiency and processing accuracy.
Cost control: By optimizing processing paths and reducing material waste, production costs can be further reduced.
5, Application and Development Trends
CNC turning
Application: Widely used in fields such as automotive parts, aerospace parts, etc.
Development trend: With the continuous advancement of technology, the machining accuracy and efficiency of CNC lathes will be further improved, while developing towards more advanced manufacturing systems.
CNC milling machine processing
Application: Widely used in fields such as mechanical manufacturing, mold manufacturing, and electronic manufacturing.
Development trend: With the diversification of market demand, CNC milling machines will pay more attention to the development of personalized customization and green manufacturing.
In summary, there are significant differences between CNC turning parts and CNC milling machines in terms of working principles, machining objects and scope, machining accuracy and efficiency, equipment investment and cost, as well as application and development trends. The choice of processing method mainly depends on the specific requirements and production conditions of the parts.
