The focusing lens of the laser cutting machine is a relatively precise optical component, and its cleanliness directly affects the processing performance and quality of the laser cutting machine.Therefore, regular maintenance of the focusing lens is necessary, the following to share with you some tips for maintaining the focusing lens.
Maintenance of laser cutting machine focusing lens of the correct operating procedures:
1. mirror frame to remove the focusing mirror: loosen the fastening screws, in turn, remove the air nozzle and the lens barrel; first use a blowing balloon to blow away the dust on the surface of the lens.
2. If you really need to clean the lens, only use a soft cotton ball of laboratory-grade paper, dipped in an appropriate amount of acetone or high stock alcohol, and gently rub in a clockwise direction from the center of the lens rotating towards the edge.If necessary, both sides of the lens should be cleaned and scrubbed carefully.
3. install the lens barrel and air nozzle, adjust the focus, screw the fastening screws, focusing mirror installation, please be sure to keep the convex side down.
Maintenance of laser cutting machine focusing lens should pay attention to the following three points:
1. Focusing lens material for ZnSe (zinc arsenic), more brittle, afraid of falling; in the dismantling and installation should pay attention to: can not be too much force, can not collide with hard things.The surface has a permeability-enhancing film, afraid of pollution, afraid of moisture, afraid of oily, afraid of scratching; therefore, it is required to provide dry, de-oiled air in the work, do not use your hands directly to deal with the laser cutting machine focusing lens of the lens, because the skin oils and grease will have a long-lasting damage to the surface of the lens.Instead, you can operate with gloves and their specialized sets, and for smaller lenses, it is easier to use optical tweezers or vacuum tweezers.Regardless of the method used to clamp the laser cutter focusing mirror, it should only be clamped along non-optical surfaces, such as the frosted edge of the mirror plaque side.
2. Generally, the laser cutter focusing lens needs to be inspected before use and before and after cleaning.Because of the small size of most contaminants and surface defects, we often need to use magnification equipment when checking the lens.In addition to magnifying equipment, we sometimes need to illuminate the optical surface with a brighter beam of light to increase the intensity of specular reflection of surface contaminants and defects, so that contaminants and defects can be more easily detected.
3. When cleaning a laser cutter focusing mirror, always use clean wipes and optical grade solvents to prevent damage by other contaminants.Wipes must be moistened with a suitable solvent and should never be used dry.In the softness of the consideration, the available wiping paper for cotton Webril wiping paper or cotton balls, lens paper, and cotton swabs and other applicators.
Laser cutting machine focusing lens belongs to the consumables, when cleaned many times after still can not reach a high degree of cleanliness need to pay attention to the replacement, to ensure that the laser cutting machine processing efficiency, so as not to delay production.
