The origin of CNC vertical lathe is closely related to the development of CNC technology. CNC is a technology that uses computers and mathematical control systems to control machine tools and other industrial machinery.

1. Development of CNC technology: The origin of CNC technology can be traced back to the 1950s. At that time, with the advancement of computer technology, people began to explore how to use computers to automatically control the movement of machine tools to achieve higher production efficiency and precision.

2. Application of mathematical control system: Mathematical control system initially transmitted control instructions through punched paper tape. These instructions contain specific operating steps and trajectories that the machine tool needs to perform.

3. Development of vertical lathe: Vertical lathe is a machine tool with a vertical spindle, which is suitable for processing large-diameter and heavy workpieces. Traditional vertical lathes are usually manually controlled by operators, but with the maturity of CNC technology, people have begun to try to apply mathematical control systems to vertical lathes to achieve automated processing.

4. The birth of CNC vertical lathe: With the continuous advancement of computer and CNC technology, CNC vertical lathe was gradually born. CNC vertical lathe can automatically control the movement of the tool in each axis through a pre-programmed mathematical model to achieve high-precision machining of complex workpieces.

5. Improve production efficiency and accuracy: The emergence of CNC vertical lathes has greatly improved the automation of workpiece processing and reduced the reliance on human operations, thus improving production efficiency and processing accuracy. CNC systems can accurately perform a variety of machining operations, including turning, milling, drilling, and more.

The origin of CNC vertical lathe is part of the application of CNC technology in the field of machine tools. It represents the development trend of automation and digitalization in the field of mechanical manufacturing. The use of CNC vertical lathes makes the processing of large workpieces more efficient and precise, contributing to the development of the manufacturing industry.
