Application of laser cutting machine in sheet metal industry
    Sheet metal processing, which accounts for one third of the metal processing world, has a wide range of applications and appears in almost all walks of life. The cutting process of detailed sheet material (thickness below 6mm) is nothing more than plasma cutting, flame cutting, shearing machine, stamping parts, etc., among which laser cutting has been booming in recent years.

    Laser cutting has the advantages of high efficiency, high energy density, and high flexibility. Whether in terms of accuracy, speed or efficiency, it is the only choice for the sheet metal cutting industry. In a sense, the laser cutting machine has brought a technological revolution to sheet metal processing.

    Laser cutting has the advantages of high efficiency, high energy density, and high flexibility. Whether in terms of accuracy, speed or efficiency, it is the best choice for the sheet metal cutting industry.

    As a precision processing method, laser cutting can cut almost all materials, including two-dimensional and three-dimensional cutting of thin metal plates. The laser can be focused into a small spot for fine and precise processing, such as the processing of micro slits and micro holes. In addition, it does not require the use of tools in the processing process, which is non-contact processing and has no mechanical deformation. Some traditionally difficult to cut or low-quality plates can be solved after laser cutting. Especially in the cutting of certain carbon steel plates, laser cutting has an unshakable position.

    Daily maintenance of laser cutting machine

    Daily maintenance of laser cutting machine The price of laser cutting machine is not low, ranging from hundreds of thousands to millions. Therefore, it is necessary to extend the service life of the laser cutting machine as much as possible, to better save production costs, and to win greater benefits.

    This shows that the daily maintenance and maintenance of the laser cutting machine is very important. Mainly explain from the following aspects:

    First, replace the circulating water and clean the water tank: make sure that the laser tube is filled with circulating water before the machine works. The quality and temperature of the circulating water directly affect the service life of the laser tube. Therefore, it is necessary to periodically replace the circulating water and clean the water tank. It is best to do it once a week.

    Second, protect the cleanliness of the lens: there will be some mirrors and focusing lenses on the machine. The laser light is emitted from the laser head after being reflected and focused by these lenses. The lens is prone to dust or other contaminants, which can cause laser abrasion or damage to the lens. So wash your lenses every day.

    At the same time, please note: 1. The lens should be wiped gently, and the surface coating should not be damaged; 2. The wiping process should be handled gently to prevent it from falling; 3. When installing the focusing lens, be sure to keep the concave surface facing down.

    Cleaning of laser cutting machine
    Guide rail cleaning: Guide rails and linear shafts are one of the core components of the equipment, and their function is to guide and support. In order to ensure the high processing accuracy of the machine tool, the guide rails and straight lines are required to have high guiding accuracy and good motion stability.

    During the operation of the equipment, a large amount of corrosive dust and smoke will be generated during the processing. These fumes will be deposited on the surface of the guide rail and linear shaft for a long time, which will have a great impact on the processing accuracy of the equipment. The formation of corrosion points on the surface of the guide rail spool will shorten the service life of the equipment. So clean the machine railings every half month. Turn off the machine before cleaning.

    Tighten the screws and couplings: After the motion system works for a period of time, the screws and couplings at the motion connection will loosen, which will affect the stability of mechanical motion. Therefore, observe the transmission components during the operation of the machine.  There are no unusual sounds or abnormal phenomena. If problems are found, they should be consolidated and maintained in time.

    At the same time, the machine should tighten the screws one by one with tools after a period of time. The first firmness should be about one month after use.

    Optical path detection: The optical path system of the machine is completed by the reflection of the mirror and the focusing of the focusing mirror. The focus mirror in the optical path does not have an offset problem, but the three mirrors are fixed and offset by the mechanical part. It is more likely that although there is no deviation under normal conditions, it is recommended that the user check before each work Whether the optical path is normal. Every other week, you must check the lubrication of X-axis guide rails and screws, Y-axis guide rails and screws, Z-axis guide rails and screws, to maintain the lubrication of all moving parts, and to extend the service life of the X, Y, and Z-axis guides.

    Depending on the workshop environment, check the contamination of the reflector and focusing lens surface from time to time (at least once a month), and clean the optical lens in time to ensure its service life.

    Clean up debris from the exhaust vent regularly to ensure ventilation. effect.

    Check the filter in the gas circuit regularly, and remove the water and debris accumulated in the filter in time.

    Regularly check whether the screws of the travel switch bracket and shooter bracket are loose.

    The dust on the ventilator filter of the control cabinet should be cleaned in time to ensure good ventilation and facilitate the heat dissipation of internal electrical components.

    Clean the bed and sundries in the protective leather hole of the guide rail in time to avoid damage to the guide rail and extend the service life of the guide rail.

    After installing the machine tool, after a period of use, the level of the machine tool should be adjusted to ensure the cutting accuracy of the machine tool.
