Numerical control vertical lathe is a kind of machine tool equipment with high precision and efficiency. If we want to ensure the quality of machining and the life of tools, it is necessary to master the principle of tool alignment. The tool alignment principle of numerical control vertical lathe is as follows:

First, we need to understand the meaning of tool alignment. Tool alignment means to make the cutting edge of the tool coincide with the center of the workpiece. The purpose is to make the machining accuracy improve, reduce the tool wear, and prolong the service life of the tool.

Secondly, we need to understand the steps of tool alignment. The specific steps are as follows:

1. Fix the tool holder: The tool holder is placed on the turret of the vertical lathe and fixed by bolts. The position of the tool holder can be adjusted by the turret.

2. Install the tool: The tool is installed on the tool holder, and the tool should be fixed tightly to prevent slipping during machining.

3. Adjust the tilt angle: In order to ensure the accuracy of centering, the tool holder needs to be tilted at a certain angle. Generally, the angle of inclination is 1 degree.

4. Adjust the position of the tool: Adjust the position of the tool, so that the tip of the tool coincides with the center of the workpiece.

5. Lock the tool holder: After completing the above steps, lock the tool holder with bolts. At this time, the tool has been aligned and can start machining.

Finally, we need to understand the importance of tool alignment. Tool alignment is an important prerequisite for machining accuracy and tool life. If the tool is not aligned, it will cause uneven cutting force during machining, which will seriously affect the machining accuracy and tool life of the machine. Therefore, the tool alignment must be done well before machining.

In conclusion, the tool alignment principle of numerical control vertical lathe is very important. Only by mastering the principle of tool alignment, can we ensure the machining accuracy and improve the life of the tool. We must pay attention to the tool alignment during machining, and do a good job of tool alignment as the premise of machining work.
