Common tool alignment methods for CNC machining centers

Simply put, the commonly used tool setting methods for drilling and CNC machining centers include tool setting instruments, active tool setting, and trial cutting method tool setting.

Due to the fact that a complete machining process for a workpiece may involve several or even dozens of cutting tools, the trial cutting method is relatively primitive and has poor tool accuracy, so it is rarely used. Let's focus on the first two typical knife alignment methods:

1. Active tool alignment method: Active tool alignment is achieved using the tool detection function of CNC machining center equipment. This equipment can actively and accurately measure the length of each tool in various coordinate directions, and actively correct tool error values. The entire detection and correction process can be completed on the basis of normal machine operation. This tool alignment method relies entirely on electronic control equipment, eliminating human error in tool alignment, resulting in higher tool accuracy and better tool power.

2. Tool setting method using tool setting instrument: Selecting a tool setting instrument for tool setting is the primary method for tool setting in CNC machining centers due to its high economic efficiency. There are two types of tool alignment: internal tool alignment and external tool alignment. The external tool setting instrument needs to be calibrated outside the machine tool in advance, and then the tool can be installed on the machine tool for use; The internal tool alignment instrument is a method of directly installing the tool at a fixed position on the machine tool for measurement.
