3 Useful Ways To Centering In CNC Machining-Qidu Metrology

Centering in CNC machining is the process of accurately locating the reference point of a workpiece. This is crucial for ensuring precise and error-free machining operations. If centering is not done correctly, it can lead to significant errors or even scrapped parts. Therefore, mastering center techniques is an essential skill for every CNC operator.

Common Centering Methods

There are three primary methods for centering workpieces in CNC machining:

1.Dial Indicator (DTI) Center: This method utilizes a dial indicator mounted on the machine spindle to measure the distance between the spindle centerline and the workpiece surface. While effective, DTI centering requires manual operation, making it time-consuming and susceptible to human error. Its limitations have led to its gradual decline in popularity.

2.Edge Finder Center: An edge finder, also known as a centering rod, is used to locate the edges of the workpiece. By touching the edge finder to the workpiece and recording the machine coordinates, the center can be calculated. However, this method relies on visual judgment and is limited to workpieces with edges larger than 10mm in diameter.

3.Machine Tool Probe Center: This method employs a machine tool probe, which is a highly accurate touch sensor integrated into the CNC machine. The probe is programmed to touch the workpiece at multiple points, and the machine’s software calculates the center based on the recorded coordinates. This method offers superior precision and eliminates human error, making it the preferred choice for modern CNC machining.
