In simple terms, the commonly used tool setting methods for drilling and tapping centers and CNC machining centers mainly include tool setting instrument tool setting, active tool setting and trial cutting method tool setting.

Since a complete machining process of a workpiece may involve several or even dozens of tools, the trial cutting method is relatively primitive and the tool setting accuracy is poor, so it is rarely used. Let Shengyang take you to take a look at the first two more typical knife-setting methods:

1. Active tool setting method: Active tool setting is completed by using the tool detection function of the CNC machining center. This equipment can actively and accurately measure the length of each tool in each coordinate direction, and can actively correct the tool error value. The detection and correction process can be completed on the basis of the normal operation of the machine tool. This tool setting method is completely completed by electronic control equipment, which eliminates the error of human tool setting, so the tool setting accuracy is higher and the tool setting power is better.

2. The tool setting method of the tool setting instrument: the tool setting instrument is used for tool setting, because it is more economical, it is the primary method for tool setting of the CNC machining center. There are two types of tool setting: in-machine tool setting and external tool setting. The tool setting by the off-machine tool setter needs to be calibrated on the outside of the machine tool in advance, and then the tool can be used after being installed on the machine tool; the tool setting by the on-machine tool setter is a method of directly installing the tool on a fixed position of the machine tool for measurement. .
