How to Calibrate the Tool Magazine for an ATC CNC Router?

Publish Date: Apr. 02, 2022 Author: Jackie Publisher: EagleTec CNC Modify Date: Apr. 02, 2022

We are often be asked by users from time to time, do I need to calibrate the tool magazine after receiving the ATC CNC Router? It depends on the situation. If the machine is shipped as a whole, no additional calibration is required on your side. Suppose the gantry or the tool magazine is disassembled before the shipping. In that case, the user needs to adjust the tool magazine after reinstallation. Simply because, after the user installs the beam or the tool magazine back, the actual tool magazine position and the mechanical zero point are very likely to have a slight variable compared with the previous data.

In this post, we will take a look at how to calibrate the tool magazine for the second situation. This tutorial applies to linear ATC CNC routers with the WEIHONG system NC60A.

Tool Number Introduction

Before we dive into the specifics, let us first understand the tool number corresponding to each tool finger. When we face the tool magazine, the tool numbers are T1, T2, T3, T4, T5, and T6 from left to right.

Tool Bank Calibration Method

Manually run the automatic tool changer cnc router with the handwheel (MPG), place the T1 tool in its corresponding tool finger, and then write down the actual mechanical coordinates of XYZ in the WEIHONG system. For example, they are 313.500mm, 3746.890mm, and -274.000mm. Next, we save the three coordinate values for the T1 tool in the WEIHONG system. Analogically, we can calibrate T2~T6 tools.

Save the Actual Mechanical Coordinates in the WEIHONG Program

Let's take a closer look at the process step by step.


In the WEIHONG program of your ATC Router, click the icon with the three horizontal lines in the upper right corner of the screen, and a popup window will come out.

Double-click the corresponding row to modify the coordinate value, enter the actual values, and click OK to save. Complete!


Analogically, we do the same for T2~T6 tools.
