Cutting precision is an important part of measuring the quality of laser pipe cutting machine. However, the laser cutting accuracy is not entirely dependent on the equipment of laser pipe cutting machine, but is composed of many factors. The main factors are as follows:
1. The size of the laser tube cutter beam passing through the focus: the smaller the spot after laser beam aggregation, the higher the cutting accuracy, especially the smaller the cutting seam, the smaller the spot can be up to 0.01 mm. 2. The precision of the table of laser pipe cutting machine determines the precision of repeated cutting: the higher the precision of the table, the higher the precision of cutting.
3. The greater the thickness of the workpiece, the lower the accuracy and the larger the slit: because the laser beam is conical, the slit is also tapered, and the thickness of stainless steel with 0.3mm is much smaller than that of 2mm.
4, the material of workpiece has certain influence on laser cutting precision. In the same case, stainless steel than aluminum cutting accuracy, cutting surface is more smooth.
The error of dimension is often encountered in the process of laser pipe cutting machine, which not only affects the production efficiency, but also increases the production cost. The main causes of machining dimension error fault are as follows:
1. Signal line is abnormal. The signal line needs to be replaced at this time.
2. Poor equipment and grounding. Good grounding of equipment and computers is required at this point.
3.The computer is not working properly. The computer needs to be repaired or replaced.
4. Computer operating system malfunctioned or infected with virus. The operating system needs to be reinstalled or virus killed.
5, the application software is abnormal. Software and motion control card software will need to be reinstalled.
6, power supply is unstable or by interference signal. At this point need to install a voltage regulator or eliminate interference signals.
7, the processing program is not correct. The process needs to be checked and repaired.
8, processing parameters are not set correctly. To reset the correct processing parameters.
