some knowledge of laser cutting machine installation

Installation environment requirements

a) Power supply specifications: three-phase five-wire system, 380V 50Hz;

b)Laser and chiller: 5KVA (for 500W laser)

c) Power quality: three-phase unbalance <2.5%, line voltage fluctuation <5%.

d) Grounding protection: grounding the machine tool, grounding the pile ground on the machine side,

or connecting the machine to the ground of the power supply, requiring grounding resistance < 4Ω.

e) A site environment that requires good ventilation, no dust, no corrosion, and no pollution.

f) Install the foundation without large vibrations around the ground and drill the anti-shock.

g) The laser source is required to be installation in a 20℃ environment

h) The chiller is a special equipment for providing cooling circulating water to the laser and QBH and cutting head lens.

The cooling circulating water requires high quality pure water or distilled water.

Preparation and inspection before use

a) Check if the machine oil level is within the normal range, otherwise add the oil to the normal range.

b) Otherwise check the relevant water and gas paths to ensure that the gas and waterways are clear and leaking,

and the gas and cooling water are of normal quality and are not contaminated.

c) Check the coaxiality of the laser and the nozzle to ensure that the laser beam is emitted from the center of the nozzle.

d) Check that the nozzle meets the cutting process requirements, otherwise replace the appropriate cutting nozzle.

e) Check if the auxiliary gas for cutting is normally connected, otherwise connect the auxiliary gas for cutting and

ensure that the gas pressure has been adjusted.

Other Attention:

a) No one should, at any time, be in the direction in which the laser is facing the laser (including the red indicator light).

b) When the shutter is open, the human and non-working objects are prohibit from being expose to the laser.

c) Operators should wear protective glasses and it is strictly forbidden for the operator to leave during the operation.

d) If an abnormality occurs during the use of the machine, immediately press emergency stop switch or turn off main power.

e) During the use, the cooling water temperature and working gas pressure should be checked frequently.

f) Operate the equipment with the operation permit and observe the safety operation rules.

It is strictly forbidden for the machine tool staff to operate.

g) The laser is a Class 4 product. The laser is invisible. The beam is emit.

The lens reflection and diffuse reflection may cause damage to the human body (especially the eyes).

The personnel should pay attention to the protection and prevent the fire.

h) The exhaust gas generated during laser cutting has a great harm to the human operator.

Please ensure that the vacuum cleaner of the machine tool works normally.

i) Always keep the equipment clean and tidy, refuel according to regulations, ensure reasonable lubrication;

comply with the handover system, manage tools, accessories, and shall not be lost; if the fault is found,

stop the inspection immediately, and you should notify the maintenance in time if you cannot handle it.

j) To prevent electric shock damage, non-professional maintenance personnel are strictly prohibit

to inspect and repair the electrical control part of this machine.
