"Small fully automatic cutting CNC vertical lathe" is a small CNC machine tool designed for fully automatic cutting, with sufficient rigidity and strong power. Here is a detailed explanation of this description:

1. Small CNC vertical lathe: This refers to a small, CNC vertical lathe. The table of a vertical lathe is positioned vertically and the tools cut in a vertical direction. Small designs may be suitable where there are space constraints or where smaller machine tool dimensions are required.
2. Fully automatic cutting: Indicates that the machine tool has fully automated cutting functions without manual intervention. This may include features such as automatic tool changing, automatic workpiece clamping, automatic measurement and compensation to achieve a highly automated machining process.
3. Sufficient rigidity: This means that the structure of the machine tool is rigid enough to remain stable under high-speed cutting and heavy load conditions. Rigidity is crucial to ensure machining accuracy and surface quality.
4. Strong power: It means that the machine tool is equipped with a powerful drive system, which can provide enough power to complete various cutting operations. Strong power helps increase productivity, especially when working with difficult materials or performing heavy-duty cutting.

Such small fully automatic cutting CNC vertical lathes may be used in environments that require a high degree of automation, have limited space, or require smaller machine tool sizes. Its rigidity and strong power make it suitable for cutting operations that require high precision and efficiency, such as in mold manufacturing, parts production, etc.
