A laser cutting machine is also known as laser cutter, laser cutter machine, laser cutting system, laser cutting equipment, laser cutting table, laser cut machine, laser cutting tool, laser profile cutting system, laser profile cutting machine.

How Does A Laser Cutter Work? - Working Principle

Laser beam is a type of light, and like other natural light, it is produced by the transition of atoms (molecules or ions). However, it is different from ordinary light in that the laser depends on spontaneous radiation only for a very short period of time. The subsequent process is completely determined by the excitation radiation, so the laser has a very pure color, almost no divergence direction, and extremely high luminous intensity, and high coherence.

Laser cutting is achieved by applying high power density energy generated by laser focusing. Under the control of the computer, the laser is discharged by pulses to output a controlled repetitive high-frequency pulsed laser to form a beam with a certain frequency and a certain pulse width. The pulsed laser beam is transmitted and reflected through the optical path and is focused by the focusing lens group. On the surface of the processed object, minute, high-energy density light spots are formed, and the focal spot is located near the surface to be processed, and the processed material is melted or vaporized at an instant high temperature. Each high-energy laser pulse instantly sputters a small hole on the surface of the object. Under the control of the computer, the laser processing head and the material to be processed perform continuous relative movement and dotting according to the pre-drawn graphics, so that the object will be processed into the desired shape.

The technological parameters (cutting speed, laser power, gas pressure) and movement trajectory during slitting are controlled by the CNC system, and the slag at the slit is blown off by the auxiliary gas with a certain pressure.

The laser emitted by the laser generator is focused by the optical path system into a laser beam of high power density. The laser beam is irradiated onto the surface of the workpiece to bring the workpiece to a melting point or boiling point, while the high-pressure gas coaxial with the beam blows away the molten or vaporized material. As the laser beam moves relative to the workpiece, the material is slit finally, thereby achieving the purpose of cutting. Different laser powers can different workpieces with different thickness. Generally speaking, higher laser power for thicker workpiece. You should make the appropriate choice according to your requirements.

How To Use A Laser Cutter? - Basic Operation Guide For Beginners

Laser cutting is a non-contact subtractive manufacturing technology that uses laser to cut materials that are mainly used in industrial manufacturing applications. The working principle of laser cutting is to guide the output of a high-power focused laser beam to melt the material so that the edge has a high-quality surface finish. The industrial-grade maintenance-free laser cutting system has outstanding technical advantages, ultra-low power consumption, reduced operating costs, and repeatable and accurate laser positioning performance, which sets a new benchmark for the cutting of complex patterns and establishes a new standard for process quality inspection.

First, we should check all the connections of the laser machine (including power supply, PC and exhaust system) are correct and inserted correctly. Visually check the condition of the laser machine. Ensure that all mechanisms move freely, and check that there is no material under the processing table. Ensure that the work area and optical components are clean, and clean if necessary. For more information on this issue, please read the "General Maintenance" section of the operation manual. Check the exhaust system and start the cooling system if necessary. Check whether the filter and activated carbon of the exhaust system are installed in accordance with the instructions. After checking, close the protective cover.

Next, press the main switch to turn on the main power of the laser machine. Turn the key switch on the control panel. This is machine-specific and not relevant to all lasers. If all the covers fixed with safety circuit breakers are closed, the system will start to quote after startup. After turning on the laser machine, the laser bed will move all the way down while the laser head moves to the zero position (located in the upper left corner). When there is a sound and the LED light flashes slowly and steadily, the reference process has been completed correctly and the machine is ready to start operation.

1. Place the raw material to be cut steadily on the laser cutting table;

2. According to the material and thickness of the raw material to be cut, adjust the system cutting parameters of the equipment correspondingly;

3. Choose suitable nozzles and lenses, and inspect them to make sure their appearance and cleanliness are intact;

4. Repeatedly debug the equipment and adjust the focus point of the cutting head to a suitable position;

5. Check and adjust the nozzle of the equipment and adjust it to the center;

6. Adjust and calibrate the sensor of the laser cutting head;

7. According to your own cutting needs, select a suitable laser cutting gas, and check whether the jet is in good condition;

8. Try cutting the raw material to be cut, and observe whether the section is smooth and the cutting accuracy is accurate. If there is a deviation, adjust the equipment parameters accordingly until the proofing meets the requirements;

9. Draw and typeset the graphics to be cut, and import them into the cutting system;

10. Adjust the position of the cutting head. After all preparations are completed, you can start cutting;

11. During the operation, the staff needs to be present at the scene to observe the cutting condition of the equipment, and if there is an emergency, they need to quickly press the brake button;

12. When the equipment is stopped, always clean the guide rails, wipe the rack of the equipment, and often apply lubricating oil on the guide rails to ensure that there is no debris;

13. The motor ring should be cleaned frequently to ensure the normal operation of the machine and accurate cutting, so as to ensure the cutting quality;

14. The staff must use a vacuum cleaner to suck away the dust and debris from the machine every week to ensure the cleanliness of the equipment;

15. To ensure the service life of the machine, it is necessary to check the straightness and verticality of its track every six months, and if any abnormality is found, it must be maintained and debugged in time.

How To Maintain A Laser Cutter? - Care And Maintenance

When you do laser cutter care and maintenance, pay attention to cleaning the lenses, guide rails, and cleaning workbench debris everyday.

Lens cleaning method: when cleaning the lenses, absolute ethanol or 98% alcohol must be used as the cleaning solution, and a small amount of absorbent cotton should be lightly moistened with alcohol and then put on the lens.

Directional light scrubbing, and finally wipe the lens with dry cotton to make the lens bright and transparent.

Note: Scrubbing too hard will easily wipe off the coating on the lens until the lens is damaged.

The cleaning method of the guide rail: first remove the stains on the guide rail and process it After crushing the material, add a little bit of clean lubricant to the guide rail, and move the guide rail so that the clean lubricant can be evenly distributed on the guide rail. Be careful not to thicker lubricating oil (butter). This kind of lubricating oil attached to the guide rail can easily cause the sticking and twisting of processed materials and dust, so as to damage the sliding block and the guide rail.

Cleaning method of the working platform: The working platform has zinc for workbenches such as ferroalloy, honeycomb, crawler, knife strips and more, first clean up the processed scraps on the workbench. The crawler workbench needs to be used for half a year to add a little clean anti-rust oil on the crawler to do rust prevention treatment, other workbenches do not need.

Note: the work platform cannot be easily cleaned with water. It is easy to make the work platform rust and accelerate the oxidation of the work.

The correct operation process of maintaining the focus lens of laser cutting machine:

1. Take out the focusing lens from the frame: loosen the fastening screw, and take off the air nozzle and lens barrel in turn, first use a blowing balloon to blow off the dust on the lens surface.

2. If you really need to clean the lens, you can only use a laboratory-grade paper soft cotton ball, dip an appropriate amount of acetone or high-content alcohol, and gently rotate it clockwise from the center of the lens to the edge. When necessary, both sides of the lens need to be cleaned. Care should be taken when scrubbing.

3. Install the lens barrel and air nozzle, adjust the focus, tighten the fastening screws, and keep the convex surface downward when installing the focusing lens.

Pay attention to the following three points when maintaining the focusing lens of laser cutter kit:

1. The focusing lens material is ZnSe (arsenic zinc), which is brittle and afraid of falling; pay attention when disassembling: do not use too much force, and cannot collide with hard objects. There is an antireflection film on the surface, which is afraid of pollution, humidity, oiliness, and scratching; therefore, it is required to provide dry and degreasing air during work. Do not directly handle the focusing lens by hand, because the skin is oily. It will cause permanent damage to the lens surface. On the contrary, you can wear gloves and its special set for operation. For smaller lenses, it is more convenient to use optical tweezers or vacuum tweezers. No matter what method is used to clamp the focusing lens of the laser machine, it can only be clamped along the non-optical surface, such as the frosted edge of the mirror plaque.

2. Under normal circumstances, it is necessary to check the condition of the focusing lens before use and before and after cleaning. Because most contaminants and surface defects are relatively small in size, we often need to use magnifying equipment when inspecting lenses. In addition to magnifying equipment, sometimes we need to illuminate the optical surface with a relatively bright light to enhance the specular reflection intensity of surface contaminants and defects, so that contaminants and defects can be found more easily.

3. When cleaning the focusing lens, you should always use clean wipes and optical grade solvents to prevent damage by other contaminants. The wipe paper must be moistened with a suitable solvent, and it must not be used dry. In consideration of softness, the usable wipes are pure cotton wipes or applicators such as cotton balls, lens tissues, and cotton swabs.

Although it is troublesome to clean and maintain the focusing lens, good cleaning and maintenance operations can extend the service life of the lens, improve efficiency and save costs for enterprises, which can be described as a multiplier with half the effort. When the cleanliness is still not reached after many times of cleaning, please pay attention to replace it to ensure the processing efficiency of the laser cutting machine, so as not to delay production.
