Laser cutting machine is a commonly used modern processing equipment. There will always be some headache problems during the use, especially the abnormal reset of the laser cutting machine. This is also a concern for everyone. Here is a brief introduction to the solution to the abnormal reset of the laser cutting machine.
How to solve the problem of abnormal reset?
1. Check whether the sensor is dirty, poorly contacted or damaged by dust (wipe the dust on the sensor or replace it);
2. Check whether the data line of the flexible guide belt is in poor contact or damaged (trim the data line and reinsert or replace the data line);
3. Check whether the grounding wire contacts reliably or whether the high-voltage wire is damaged (re grounding or replacing the high-voltage wire);
4. The motor wire is in poor contact.
How to solve the problem of abnormal reset of laser cutting machine?
The omission and initialization of the laser cutting machine are incorrect, and the data has been sent (corrected); The operation sequence is reverse (re input); Electrostatic interference (check whether the grounding wire falls off); The cleaning hook is misplaced and not closed, please check whether the software parameter settings are correct (reset); Computer system error (reinstall the operating system and software); Check whether the tightness of the left and right belts is the same, or whether the rear belt is loose (the belt is fastened); Check whether the belt or synchronous pulley slips or trips (tighten the synchronous pulley or belt); Check whether the beam is parallel (readjust the left and right belts).
What are the laser drilling methods of laser cutting machine?
At present, as a new tool, laser cutting machine has become more and more mature in all walks of life. So how does the laser cutting machine use the laser to punch holes? Normally, a small hole must be made in the plate. In the earlier laser cutting machines, the punch was used to punch holes first, and then the laser was used to cut from the small holes.
For the laser cutting machine of the pressure loading device, the laser drilling method is mainly embodied in the following two aspects
1. Pulse perforation: pulse laser with peak power is used to melt or vaporize a small amount of materials. Air or nitrogen is usually used as an auxiliary gas to reduce cavity expansion due to exothermic oxidation. The air pressure during cutting is less than the oxygen pressure. Each pulsed laser produces only a small beam of particles, which are then gradually deepened, so it takes a few seconds for a thick plate to be punctured. After the perforation is completed, cut with oxygen instead of auxiliary gas immediately. In this way, the hole diameter is smaller than the blasting hole, and the hole quality is good. The laser used for this purpose should not only have higher output power, but also have more important temporal and spatial characteristics of the beam. Therefore, the common cross current CO2 laser cannot meet the requirements of laser cutting.
2. Blasting perforation: after continuous laser irradiation of the material, a pit is formed in the center, and then the molten material is rapidly removed through the oxygen flow coaxial with the laser beam, thus forming a hole.
