How to maintain laser cutting machine?


By laserman123, 2017-10-19

Laser cutting machine focus lens is a relatively sophisticated optical components, the degree of cleanliness of the laser cutting machine directly affect the processing performance and quality. Therefore, the timing of the maintenance of the lens is very necessary, the following easy network will give you some tips to maintain the focus of the lens. Maintenance of the burning laser cutting machine Focusing the correct operation of the lens flow:

First, remove the focusing lens in the frame: loosen the fastening screw, remove the gas nozzle and the tube in turn; blow the dust from the surface of the lens with a blower; then, if you really need to clean the lens, you can only use the laboratory level Paper soft cotton ball, dipped in the right amount of acetone or high degree of alcohol, gently clockwise from the center of the lens rotation to the edge of the rub. When necessary, both sides of the lens need to be clean, scrub should be careful and meticulous; Finally, install the tube and the gas nozzle, adjust the focal length, tighten the tightening screws, focusing lens installation, please keep the convex face down.

Focus lens material for the ZnSe (zinc arsenic), more brittle, afraid to fall; in the disassembly should pay attention: not too hard, can not collide with the hard objects. The surface of the anti-reflective film, fear of pollution, fear of wet, afraid of oil, afraid of scratches; it is required to provide dry, oil to the work of the air, do not directly handle the green laser light cutting machine lens lens, because the skin grease Will have a permanent damage to the lens surface. On the contrary, you can carry gloves and their special sets of equipment to operate, for smaller lenses, the use of optical tweezers or vacuum tweezers will be more convenient. No matter what method to clip laser cutting machine focus lens, can only be held along the non-optical surface, such as mirror edge edge of the matte edge.

Under normal circumstances, before and after use and cleaning need to check the laser cutting machine focus lens situation. Because most of the contaminants and surface defects are smaller in size, we often need to use the magnifying device when checking the lens. In addition to amplifying the equipment, sometimes we also need to use a bunch of relatively bright light to illuminate the optical surface, enhance the surface contaminants and defects of the specular intensity, so that you can more easily detect pollutants and defects.

Flame cutting as the original traditional way of cutting because of its low investment, the past is not demanding on the quality of processing, when asked too much plus a machining process can be resolved, the market is very large. Plasma cutting and fine plasma cutting with flame cutting is similar to the heat affected area is too large, the accuracy is much larger than the flame cutting, the speed of the magnitude of the leap, became the main force in the plate processing. High-pressure water cutting is the use of high-speed water jet doping in the implementation of the sheet metal diamond cutting, it is almost no restrictions on the material, cutting the thickness of almost 100mm or more, the ceramic, glass and other materials when the heat is easy to burst Can be cut, copper, aluminum and other high-reflective material on the high power laser pointer water knife can be cut, and laser cutting there is a big obstacle. The shortcomings of water cutting is the processing speed is too slow, too dirty, not environmentally friendly, consumables are higher.

Laser cutting is a sheet metal processing technology revolution, is the sheet metal processing in the "processing center." Laser cutting a high degree of flexibility, cutting speed, high production efficiency, product production cycle is short, for customers to win a wide range of markets. Laser cutting no cutting force, no deformation of the processing; no tool wear, good material adaptability; whether it is simple or complex parts, can be used laser a rapid rapid cutting; its narrow cutting, cutting quality, high degree of automation, operation Simple, low labor intensity, no pollution; can achieve automatic cutting nesting, nesting materials, improve the utilization of materials, low production costs, good economic returns.

When cleaning a laser cutter focusing lens, often use clean wipes and optical grade solvents to prevent damage from other contaminants. Wipe the paper must be wet with a suitable solvent, do not dry use. In the case of softness, the available wipes are cotton Webril wipes or cotton applicators such as cotton balls, lens paper, and cotton swabs.

Laser cutting machine focus lens This is a consumable, when the cleaning after many times still can not reach a high degree of cleanliness should pay attention to replacement, to ensure that the red laser cutting machine processing efficiency, so as not to delay production.
