The fiber laser cutting machine will use the cutting head in the cutting process. How can the laser cutting head control the distance from the workpiece well? This is inseparable from the sensor of the laser cutting head. Let’s check together what sensor of laser cutting head can do.
In the cutting process, two factors directly affect the cutting quality: the distance between the cutting head and the workpiece, the perpendicularity between the nozzle and the workpiece surface.
So in order to increase the cutting quality and reduce the generation of waste, it is necessary to install some sensors on the cutting head to ensure that it can produce stable cutting quality and increase process safety.

When the shape of the workpiece changes and surface is uneven, the sensor automatically detects the change and automatically adjusts the height according to the change, so that the distance between the laser cutting head and the surface of the workpiece remains the same, and the material can be processed faster. The displacement sensor is basically capacitive, its structure and shape are adapted to the cutting head, and it is also equipped with a detection signal processing unit.

Displacement measurement is a basic measurement work. According to whether the sensor is in contact with the workpiece, the displacement sensor can be divided into two types: contact type and non-contact type. Compared with contact type sensors, non-contact type sensors can guarantee high resolution. At the same time, it has the advantages of fast dynamic response and low hysteresis error.
