There are significant differences between CNC vertical lathes and milling machines in many aspects:

1. Processing objects and methods:

CNC vertical lathe is a kind of equipment for processing large plate and cover parts. It is especially suitable for processing of medium and small parts. Its main shaft radial bearing and axial bearing adopt high-standard bearings to ensure rotation accuracy and load-bearing capacity. In addition, its symmetrical layout, reasonable reinforcement and multiple tempering treatments ensure the long-term stability of the machine tool accuracy.

Milling machines are mainly used for milling, drilling and boring of workpieces. It can process flat surfaces, grooves, various curved surfaces, gears, etc. With the development of technology, CNC milling machines have gradually replaced traditional milling machines with their high processing accuracy, high stability and high efficiency.

2. Adaptability to parts processing:

CNC milling machines have strong adaptability and flexibility in parts processing, and can process parts with particularly complex contour shapes or difficult-to-control dimensions, such as mold parts, shell parts, etc. It can also process parts that cannot be processed or are difficult to process with ordinary machine tools, as well as parts that require multiple processes.

Although CNC vertical lathes also have high processing accuracy and stability, they may not be as flexible as CNC milling machines in processing complex shapes or parts that require multiple processes.

3. Structure and features:

CNC vertical lathes usually adopt a large-size box layout to support overweight cutting, and the finite element analysis method is introduced to carry out special designs for high efficiency, high rigidity, heavy cutting and other working conditions. Its hydraulic system uses external circulation to effectively take away the cutting heat of the machine tool and ensure stable temperature during machine tool operation.

The milling machine mainly uses the milling cutter to perform rotational motion on the workpiece. Its structure and working principle are different from that of the vertical lathe.

To sum up, there are obvious differences between CNC vertical lathes and milling machines in terms of processing objects, processing methods, adaptability of parts processing, structure and characteristics. Which equipment to choose depends mainly on the specific processing needs and workpiece characteristics.
