Laser cutting machine setup (Introduction to laser cutting machine setup guide)

The settings of the laser cutting machine are unknown or half-understood by many people, which leads to the fact that once some problems arise, we don’t know how to solve them, and then we can only wait for the manufacturer to deal with it, which delays a lot of time back and forth, Hebei Hongte The equipment provides you with a guide for setting up the laser cutting machine.

Laser cutting parameters include cutting speed, power, gas cutting Laser cutting analyzes the cutting quality and cutting efficiency separately, and analyzes the impact of different types. However, through the combination of laser cutting to achieve various parameters required for a good configuration, different factories will determine the quality and efficiency to a certain extent according to the cost structure. Efficiency is paid special attention to and weighed.

1. Cutting speed. Laser cutting laser head can move along the part shape in unit time. The higher the laser cutting speed, the shorter the cutting time, and the higher the laser cutting production efficiency. However, when other parameters are fixed, the laser cutting speed is not linearly related to the cutting quality. A reasonable cutting speed is a range value. Below this range value, the energy of the laser beam remains too much on the surface of the part to form excessive combustion. If the range value is exceeded, the energy of the laser beam is too late to completely melt the part material, resulting in The cut is impenetrable.

2. Laser output power. Laser output power is the output energy of the laser system, and laser cutting represents the ability of the laser beam to melt materials per unit time.

3. Focus position. The laser output is focused on the point with the highest power density through a special lens. The focal spot diameter is proportional to the focal depth of the focusing lens. Laser cutting is set according to different thicknesses at different positions. The correct focus position is an important condition for obtaining stable cutting quality. The cutting quality of laser cutting is related to the laser beam, but also related to the characteristics of the laser beam focusing system, that is, laser cutting focus The size of the rear laser beam has a great influence on the quality of laser cutting.

4. The pressure of the auxiliary gas. An incision is formed in the gap. Proper air pressure can help speed up the laser cutting speed, and the auxiliary gas pressure also affects the cutting efficiency of the fiber laser cutting machine. If the thickness of the material processed by laser cutting increases or the cutting speed is slow, the gas pressure should be appropriately reduced. Cutting with lower air pressure can prevent frosting.

5. Nozzle distance. The focused laser is applied to the surface of the part through a copper nozzle. The distance between the workpiece and the laser nozzle is called the distance of the nozzle. The distance from the nozzle to the part is measured based on flow and pressure. The blowing force of the gas that is too far away is too large, and the exhaust gas flow is too large, which will affect the splashing. The appropriate distance is 0.8-1.0mm. Choose different types of nozzles according to different material thicknesses.

The setup of laser cutting machine has 4 parts :

Computer

Laser cutting machine

Air compressor

Laser cutting machine is in There is an on/off in the lower left corner of the laser. The main control panel is located on the front.

The laser cutting machine has several important safety features. There is a magnetic switch on the glass cover. If the lid is opened while the laser is running, the lens device will continue to move, but the laser will stop emitting. This means that it is very difficult (if not impossible) to burn yourself with a laser. A similar device is installed on the front door.

Go: Start or stop a job or process

Stop: Stop a process. It will stop immediately when rasterizing. When booting, it will only stop after completing the current path

Reset: move the head back to the current position

Set Home: Set the laser zero or starting point

X/Y Off: Press this button, then release the motor, and manually move the laser head

Indicator: Turn on the red indicator

Concentration: Press this Button, and then press the up and down buttons to raise or lower the bed. Using this process and focusing tool, you can focus the laser.

∆/∇: Cycle through work or increase or decrease power, speed or bed height

Power: when rasterizing, you can press this button with the arrow keys Adjust power

Speed: When rasterizing, you can press this button with the arrow keys to adjust the speed
