Vertical CNC lathe is a machine tool controlled by computer digital signals. During operation, the prepared processing program is input into a computer dedicated to the machine tool, and then the computer instructs the servo motors of each coordinate axis of the machine tool to control the sequence, speed and movement amount of each component of the lathe, in conjunction with the selected spindle speed. In combination, workpieces with different shapes can be turned. Vertical CNC lathes are divided into three categories according to their functions: economical CNC lathes, ordinary CNC lathes and turning centers.
1. Economical CNC lathe
The economical CNC lathe is an improved design based on the ordinary horizontal lathe. It generally uses an open-loop servo system driven by a stepper motor, and its control department usually uses a single-chip microcomputer. Economical CNC lathes have low cost, poor automation and performance, and low turning accuracy. They are suitable for turning rotary parts with low precision requirements.
2. Ordinary CNC lathe
Ordinary CNC lathes are CNC lathes that are specially designed in terms of structure and equipped with a universal CNC system according to the requirements of turning processing. Its CNC system has strong functions, high degree of automation and high machining accuracy. It can control the X and Z coordinate axes at the same time. It is widely used and is suitable for turning general rotary parts.
3. Turning center
The turning center is based on the ordinary CNC lathe, adding a C-axis and a milling power head. The more advanced CNC lathe has a tool magazine that can control the three coordinate axes of X, Z, and C. Due to the addition of the C-axis and milling power head, its processing functions are greatly enhanced. In addition to general turning, it can also perform radial and axial milling, curved surface milling, eccentric hole and radial hole processing, etc.
