How to use laser cutting machine safely

A, formulate and abide by the equipment operation procedures.

1) Formulate and strictly abide by the operation procedures of the equipment.

2) Check the safety facilities of the system before starting, especially the shutter switch.

3) Maintain the machine in time.

Second, the scene must be equipped with fire equipment.

Fire fighting equipment such as fire extinguishers should be equipped next to the laser cutting machine, and operators should know its layout and usage.

Thirdly, the position of the laser cutting machine tool is managed as a dangerous area.

The area where the equipment is located should be designated as a dangerous area, and a retractable isolation belt should be set around the area to ensure that the laser leaked out of the dangerous area is below the first-class achievable emission limit.

Warning signs should be set at the entrances and exits of dangerous areas, including:

Invisible laser radiation

No outsiders are allowed in.

Pay attention to protect your eyes.

When the laser cutting machine is working, no one is allowed to approach the dangerous area.

Four, it is forbidden to fatigue, drunk operation.

The use of laser processing equipment, such as laser cutting machine, is risky, and if it is neglected, it is likely to cause injury. Therefore, it is forbidden to operate the laser cutting machine after fatigue and drinking.

Five, it is forbidden to look directly at the laser beam.

The laser beam wavelength of Bond IPG fiber laser is 0.98μm(980 nm), which is in the infrared radiation range of the spectrum and is invisible. Because it is invisible, it is easy to be ignored, which will cause harm to the eyes. Never look straight into the light path!

Six, it is forbidden to open the laser cover in the process of operation.

During the operation of the laser, it is forbidden to open the cover of the laser.

It is forbidden to open the protective door during the whole operation of the closed fiber laser cutting machine.

Seven, it is forbidden to wear metal objects for maintenance operation.

Without maintenance qualification, it is forbidden to repair or adjust the laser.

When repairing or adjusting the laser, it is forbidden to wear metal ornaments or articles (such as rings, bracelets, watches, earrings, metal belt buckles, etc.). ). Otherwise, you may get an electric shock.

The maintenance and adjustment of laser and light guide system is extremely dangerous. In order to prevent accidents, it is forbidden to carry out maintenance work alone, and "two people walk together".

Eight, it is forbidden to output laser beams when there is no target.

When there is no target, it is forbidden to output the laser beam. Otherwise, the laser beam directly irradiates the equipment, which will cause equipment and personal accidents.

Nine, it is forbidden to pile up flammable items in the laser cutting machine processing area.

It is forbidden to pile up flammable items such as paper, tarpaulin and oil near the laser cutting machine.

When oxygen is used as cutting auxiliary gas, there should be no oil stain on the surface of the material. Otherwise, it is easy to cause a fire.

Ten, the machine is working, it is forbidden to enter the danger zone.

The dangerous area of the laser cutting machine is the whole workbench. If it is an open workbench, it extends 500mm outward. The processing zone is the main danger zone. In this area, the moving light beam may hit the human body; Moving beams and fixed beds, doors and bases may squeeze the human body; Sharp objects or needle-shaped support thimbles may stab people; High power density laser may cause fatal damage to human body.

XI. Keep the workplace ventilated, clean and well lit.

The working area of the laser cutting machine should be well ventilated to facilitate the discharge of harmful gases (such as nitrogen overflow caused by pipe bursting or gas cylinder leakage). Ensure that all harmful gases and substances and laser working gas during processing are discharged to the outside.

All gas cylinders should be placed on the gas cylinder rack, and placed against the wall as far as possible to keep them stable and tidy.

In the laser safety management area, good lighting should be ensured.

Twelve, wear protective glasses and protective clothing.

The operator of the laser cutting machine or the person who is close to the laser in the process of using the laser should wear appropriate protective glasses (with side covers corresponding to the corresponding laser wavelength) as far as possible. The purpose of wearing protective glasses is to prevent the eyes from being exposed to possible laser radiation, and to prevent the damage to the eyes caused by metal splash, fragments flying out of the lens burst and high-voltage pipeline burst during cutting.

Thirteen. Key management

When the operator leaves the laser cutting machine tool, he should remove the switch key and laser key of the equipment control power supply to prevent misuse by other personnel.

Fourteen, properly handle the damaged optical devices

When the focusing mirror and reflector and their coatings are overheated or otherwise damaged, toxic substances will be formed. Wear latex gloves when handling, and don't touch them with your bare hands. Damaged lenses cannot be treated as routine waste, but should be treated by professional institutions.
