Working principle
The laser is a light, which is caused by the atomic (molecule or ion) transition, and is caused by spontaneous radiation. Although the laser is light, it is clearly different from ordinary light, and the laser is only dependent on spontaneous radiation in the initial very short time. Since the process is completely determined by the haircut, the laser has very pure color, almost no divergentity , Engraving machine, extremely high luminous intensity. The laser also has high coherence, high intensity, high directionality, and the laser is generated by the laser and transmitted from the mirror and is irradiated through the aggregation mirror to cause the processing article (surface) to be strong and the temperature has increased dramatically. This point quickly melts or vaporizes, and the operation trajectory of the laser head is used to achieve the purpose of processing.
Maintenance and Maintenance
1: Water replacement and water tank cleaning
suggestion: cleaning water tank per week and replacing circulating water once.
Note: It must ensure that the laser tube is filled with circulating water prior to operation.
The water quality and water temperature of the circulating water directly affect the service life of the laser tube, it is recommended to use pure water and control the water temperature below 35 ° C. Circulating water is required for more than 35 ° C. (It is recommended that the user selects the cooling machine or uses two water tanks).
Cleaning water tank: First turn the power supply, unplug the water pipe, so that the water in the laser tube automatically flows into the water tank, open the water tank, remove the water pump, remove the dirt on the water pump. Clean the water tank, replace the circulating water, restore the water pump to the water tank, and insert the water pipe connected to the water pump into the water, organize each joint. The pump is energized separately and operates 2-3 minutes (allowing the laser tube full of circulating water).
Winter in the northern region is low, it may cause water in the laser tube to nice to ice, and the antifreeze can be added to prevent water from iron, and the midwork of the laser tube can be broken.
II, fan cleaning
The fan is used for a long time, which will accumulate a lot of solid dust in the fan, so that the fan produces a lot of noise, nor It is good to exhaust and decent. When the fan suction is not enough, the power supply is first closed, and the air in the wind is removed, remove the dust in the wind, then turn the fan invert, and pull the blade inside until clean , Then install the fan.
3: Cleaning
of the lens (recommended before working every day, the equipment must be turned off)
The engraving machine has 3 The block mirror is at 1 piece focus mirror (No. 1 mirror is located at the emitting outlet of the laser tube, that is, the upper left corner of the machine is located on the left end of the beam, and the 3rd mirror is located at the top, focus of the laser head fixing portion. The mirror is located in the adjustable lens barrel in the lower portion of the laser head), and the laser is reflected by these lens and is resumed from the laser head. The lens is easily stained with dust or other contaminants, causing laser loss or lens damage, do not remove when cleaning 1 and 2 lens, only need to be carefully removed in the lens. Edge rotating wipe. The 3rd lens and the focus shot need to be removed from the frame, wipe it with the same method, and then install it after the wipe is completed.
Note: 1. The lens should be gently wiped, and the surface coating should not be damaged; 2. Wipe should be lightly put, prevent falling; 3. Please keep the concave down when the focus mirror is installed.

(recommended every half a month, shut down)
guide, straight axes as One of the core components of the device, its function is a guide and support. In order to ensure that the machine has high machining accuracy, the rails are required, and the straight line has high guiding accuracy and good exercise stability. During operation, due to a large amount of corrosive dust and smoke in the process of processing parts, these smoke and dust are deposited in the guide rail, the straight axis surface, which has a great influence on the processing accuracy of the equipment, and will In the surface of the guide rail form an etched point, shorten the equipment life. In order to make the machine to work properly, ensure the quality of the product, we must carefully do the daily maintenance of the rails and straight axes.
Note: Cleaning rails Please prepare - dry cotton cloth, lubricating oil
Engraving machine guide is divided into linear rails, roller rail, in the X direction in the YM series, using linear rails, The Y direction uses a roller guide.
Cleaning of the linear guide: First move the laser head to the rightmost (or left), find a straight rail, wipe it with a dry cotton cloth until the light is dusty, plus small lubricants (can be used for sewing machine Oil, do not use the oil), slowly push the laser head to a few times, so that the lubricant is evenly distributed.
The cleaning of the roller guide: move the beam to the inside, open the end caps on the machine, find the guide rail, use a dry cotton cloth to wipe the two side rails to contact the roller, then move the beam, put the remaining place Clean clean.
5, screws, the fastening of the coupling
Sports system After working for a period of time, the screws and couplings at the motion connection will occur. Loosen, it will affect the stability of mechanical movement, so it is necessary to observe the transmission components in the machine operation. There is no abnormal sound or abnormal phenomenon, and the problem should be sturdy and maintained in time. At the same time, the machine should have a strong screw by a time tool. The first rugged should be around the equipment for a month.
6, the optical path of the optical path
The optical path system of the laser engraving machine is completed by the reflection of the mirror and the focus of the focus mirror, in the optical path The focusing mirror does not exist, but the three mirrors are fixed by the mechanical portion, the possibility of the offset is large, although it is generally not an offset, but it is recommended that the user must check if the optical path is written before work. normal.
