How to solve the problem of abnormal reset of laser cutting machine?

As a modern commonly used processing equipment, laser cutting machines will always have some headaches during use, especially the abnormal resetting of laser cutting machines.

How to solve the abnormal reset problem?

1. Check whether the sensor is contaminated with dust, poor contact or damaged (wipe or replace the sensor);

2. Check the flexible conductive belt data cable (cut the data cable to re-plug Or replace) Whether the contact is poor or damaged;

3. Check whether the ground contact net is reliable or whether the high-voltage line is damaged (re-ground or replace the high-voltage line);

4. Motor line contact bad.

Missing engraving laser cutting machine, initialization error, sending data error (correction); the order of operation is reversed (re-enter); static electricity interference (check whether the ground wire is off ); clean up the hem error, do not close, check whether the software parameter setting is correct (reset); computer system error (reinstall the operating system and software); check whether the left and right belts are consistent, check whether the rear belt is too loose (tightened) ; Check whether the belt or synchronization wheel slips off, jumps the teeth (tighten the synchronization wheel or belt); check whether the beam is parallel (tightened).

What methods can be used for laser perforation of laser cutting machine?

As a new type of cutting tool, laser cutting equipment has been used more and more maturely in various industries. So how does laser cutting equipment use laser drilling? A small hole is usually made in the board. Compared with the early laser cutting machine and laser punching machine, the compound machine first uses a punch to punch a small hole, and then uses a laser to start cutting from the small hole.

The laser perforation method of the pressurized laser cutting machine is mainly reflected in the following two aspects:

1. Pulse perforation: adopts High-power pulsed laser can melt or evaporate a small amount of materials. Air or nitrogen is often used as auxiliary gas to reduce the hole expansion caused by exothermic oxidation. The gas pressure is lower than the oxygen pressure during cutting. Each laser pulse will produce small particles, gradually deepening, so it takes a few seconds to perforate a thick plate. When the perforation is completed, immediately change the auxiliary gas to oxygen for cutting. The diameter of the perforation is smaller, and the perforation quality is better than that of blasting perforation. This type of laser must not only have a higher output power, but also have more important time and space characteristics, so the general cross-flow CO2 laser cannot meet the requirements of laser cutting. In addition, pulse perforation must have a more reliable gas path control system to control the type of gas, pressure switching and perforation time.

2. Blasting perforation: Under continuous laser irradiation, the material forms a pit in the center, and then the oxygen flow and the laser beam coaxially act to quickly penetrate the molten material through a hole.
