The reason for the accuracy error of the CNC laser cutting machine
Cutting accuracy is an important part of measuring the quality of CNC cutting machine, but CNC cutting accuracy is not entirely dependent on the equipment itself, also is composed of many factors, mainly the following factors:
1. the laser beam through the size of the spotlight.
The smaller the spot after the laser beam aggregation, the higher the cutting accuracy, especially the smaller the cut, the light spot can reach 0.01mm.
2. the position accuracy of the work table determines the repeated precision of cutting.
The higher the precision of the work station, the higher the precision of the cut.
3. the greater the thickness of the work, the lower the accuracy, the greater the cut.
Since the laser beam is tapered and the seam is also tapered, the stainless steel with a thickness of 0.3mm is much smaller than the 2mm cut.
4. work parts material on the laser cutting accuracy has a certain impact.
In the same case, stainless steel is more accurate than aluminum, and the cut surface is smoother.
Processing size error is often encountered in the use of CNC cutting machine processing failure, this fault not only affects production efficiency, but also increases production costs. There are some main reasons for the failure of the processing size error:
1. The signal line is not correct. The signal line needs to be replaced at this time.
2. Equipment and computer grounding is not good. The device and computer need to be well grounded at this point.
3. The computer is not working properly. The computer needs to be repaired or replaced at this time.
4. The computer operating system is faulty or infected with a virus. The operating system needs to be reloaded or virus culled.
5. The application software is not correct. The drive software for the motion control card needs to be reinstalled.
6. The power supply is unstable or by interference signal. At this point, a regulator needs to be installed or the interference signal removed.
7. The processing program is not written correctly. The machining procedure needs to be checked and repaired at this time.
8. The machining parameters are not set correctly. To reset the correct machining parameters.
