When traditional cutting technology is used to cut metal materials, due to the backwardness of its processing method. It is often easy to cause low utilisation of the processed material, resulting in the loss of the processed material, as well as poor cutting accuracy and high power consumption in the cutting process. Therefore, the laser cutting machine has replaced the traditional cutting equipment and become the preferred machine for cutting metal materials. Here we will talk about the judgement criteria of processing quality when cutting metal materials with laser cutting machines.

Laser cutting machine for cutting metal materials

Judgement criteria a. After using the laser cutting machine to complete the cutting of the workpiece, observe whether the cutting surface of the cut workpiece is smooth and flat, no burrs, no concave and convex surface formation. If the above phenomenon does not occur, it means that the processing quality is relatively high. On the contrary, the processing quality is relatively low.

Judgement criteria two, after the completion of cutting, observe whether the cutting surface of the workpiece appears layer by layer of lines, if this situation occurs, then the laser in the launch of the laser beam irradiated on the surface of the workpiece, the laser beam is not concentrated and uneven, so that the processing of the workpiece cutting surface uneven phenomenon, which indicates that the processing quality is relatively low. If the above phenomenon does not occur, it means that the processing quality is relatively high.

Judgement criteria three, in the use of laser cutting machine cutting workpiece, because the main form of cutting is to use the laser to gather heat, so that the surface of the metal to produce melting to cut, if you do not control the laser power, so that the laser beam in the gathering of heat is high, will make the internal molecules of the metal material, easy to form brittle fracture phenomenon occurs. The appearance of this phenomenon indicates that the processing quality is low, and if it does not appear, it indicates that the processing quality is high.

Judgement criteria four, in the use of laser cutting machine on the workpiece cutting work, to observe the width of the cutting slit, whether in the pre-set error range, if the cutting of the wide slit after narrowing or widening, then the processing quality is relatively low. If the width of the cutting slit is within the error range, it means that the processing quality is relatively high.
