How to use laser cutting machine？

A friend who buys a machine often asks: I bought a laser cutting machine, and I have received pre-training from the manufacturer, how to use it? Especially novice friends. Everyone knows that only by mastering the specific operating steps and methods of the laser cutting machine can we better apply the laser cutting machine and better serve our production needs. So, today Leapion Laser Manager will share with you.

First of all, we must make the following preparations before using the laser cutting machine:

Check that all connections of the laser machine (including power supply, PC and exhaust system) are correct and plugged in correctly.

1. Before use, check whether the power supply voltage matches the machine's rated voltage to avoid unnecessary damage.

2. Check whether the exhaust pipe is placed with an air outlet to avoid obstructing air convection.

3. Check whether there are other foreign objects on the machine table.

4. Ensure that the working area and optical components are clean, and clean if necessary.

5. Visually check the condition of the laser machine. Ensure that all institutions can move freely.

Second, the optical path adjustment of the laser cutting machine hardware operation process

The operation of the hardware part is mainly focused on the focusing part. This part of the work is very important. Although the manufacturer has adjusted the focal length before the machine leaves the factory, when the laser cutting machine works for a long time, the optical path will inevitably be misaligned, which will affect the cutting effect. . Only the perfect cooperation of laser tube, reflecting mirror frame (A, B, C), focusing lens and corresponding adjustment device can achieve the best results and process the best products. This is the core part of the use of laser cutting machines. Therefore, it is very necessary to check the light path and adjust it regularly.

Let's take a look at the method of adjusting the optical path of the laser cutting machine:

1. For the adjustment of the first light, use masking paper to stick to the dimming target hole of reflector A, manually tap the light (note that the power should not be too large at this time), and fine-tune the base of reflector A and the laser tube bracket , Make the light hit in the center of the target hole, pay attention to the light can not be blocked.

2. To adjust the second light, move the reflector B to the remote, use a piece of cardboard to emit light from near to far, and guide the light into the cross light target. Because the remote light is inside the target, the near end must be inside the target, and then The near end and the remote spot are adjusted to be the same, that is, how the near end is, and how far the far end is, so that the cross is in the same position in both the near end and the remote spot, that is, near (far), indicating that the light path is parallel to the Y-axis guide rail. .

3. Adjust the third light (note: the cross bisects the spot left and right), move the reflector C to the remote, guide the light into the light target, shoot once at the approach end and the remote end, and adjust the position of the cross to follow The position of the cross in the proximal spot is the same, which means that the beam is parallel to the X axis. At this time, the light path is in or out, you need to loosen or tighten the M1, M2, and M3 on the frame B until the left and right halves.

4. To adjust the fourth light, use a piece of masking paper to stick to the light outlet, so that the light hole leaves a circular mark on the adhesive paper, click on the light, remove the adhesive paper to observe the position of the small hole, and adjust the frame according to the situation. M1, M2, and M3 on C until the spot is round and straight.

Third, the software operation process of the laser cutting machine

In the software part of the laser cutting machine, because the material to be cut is different, the size is also different, so different parameters need to be set. This part of the parameter setting generally requires professional personnel to set it up, and it may take a lot of time to explore it by yourself. Therefore, the setting of the parameter part should be recorded when the manufacturer conducts training.

Fourth, the steps of using the laser cutting machine are as follows:

Before cutting the material, the steps of starting the laser cutting machine are as follows:

1. Strictly follow the regulations, follow the principles of starting and shutting down, open the machine, and do not force it to close or open;

2. Turn on the air switch, emergency stop, and key switch (see if there is an alarm display for the temperature of the water tank);

3. Turn on the computer and turn on the start button after the computer is fully started;

4. Turn on the motor in turn, enable, follow, laser, red light buttons;

5. Start the machine and import the CAD drawing;

6. Adjust the initial processing speed, tracking delay and other parameters;

7. Adjust the focus and center of the laser cutting machine.

When starting to cut, the laser cutting machine operates as follows:

1. Fix the cutting material, and fix the material to be cut on the working table of the laser cutting machine;

2. According to the material and thickness of the metal sheet, adjust the parameters of the equipment accordingly;

3. Choose suitable lenses and nozzles, and check them before starting to check their integrity and cleanliness;

4. Adjust the focus and adjust the cutting head to a proper focus position;

5. Check and adjust the nozzle center;

6. Calibration of cutting head sensor;

7. Choose a suitable cutting gas and check whether its spraying state is good;

8. Try to cut the material. After the material is cut, check whether the cutting end surface is smooth and check the cutting accuracy. If there is an error, adjust the equipment parameters accordingly until the proofing meets the requirements;

9. Carry out the programming of workpiece drawings and corresponding typesetting, and import the equipment cutting system;

10. Adjust the position of the cutting head and start cutting;

11. During the operation, the staff must be present and carefully observe the cutting situation. If there is an emergency and need to respond quickly, press the emergency stop button;

12. Check the cutting quality and accuracy of the first sample.

Therefore, if we want to use the laser cutting machine safely and efficiently, we can learn the above steps. For more tips, welcome to consult Leapion Laser, Leapion Laser 7×24 hours online service!
