Takeaway: when the choose and buy our 2000w fiber laser machine for metal cutting, in addition to the economy, we also cannot ignore its effect and efficiency of fume good continuity, because in the current related to energy saving, emission reduction, green environmental protection calls for increasing, environmental monitoring, monitoring the production situation, equipment selection, the pros and cons of its environmental performance often has a veto power.
Optical fiber laser cutting machine in the job not like traditional way of plasma cutting or other cutting produced a large number of harmful smoke, but how many there will be some, it will damage to the operator and the staff's health, around for laser cutting in the workshop workshop, can use local smoke treatment combined with comprehensive ventilation to reduce and eliminate the influence, At present, most laser cutting machine manufacturers add dust removal devices on the equipment, and generally adopt wet treatment or dry treatment.
The so-called wet treatment is also called wet cutting, in fact, is to make a waterbed cutting platform, the workpiece is placed in the water or water, and then under water or close to the water to complete the cutting operation, water to capture the dust generated in the cutting process, so as to achieve the purpose of purifying the environment;
Dry treatment method is also called dry cutting, it is for cutting the working platform to increase a set of dust collecting device, and the dust captured directly transported to the dust filtration and purification equipment, unified filtration treatment after the discharge. The dust generated by cutting is basically formed under the cutting of the workpiece, so the suction negative pressure cutting platform has become the most common dust collecting device. In order to save equipment investment and improve air extraction efficiency, that is, to achieve a higher amount of dust collection with a smaller suction volume - only for the area in the cutting process for dust treatment, so the cutting platform along the direction of the cutting machine leading rail will be divided into (uniform) closed small area, side open air outlet. The working form of suction tuyere is side suction type mobile suction tuyere and suction chamber side wall valve type suction tuyere.
Among them, the former is widely used because of its simple structure, reliable operation and good dust removal effect.
The focus lens material is relatively brittle and easily broken, so it should be paid attention to not using too much force or colliding with hard objects when disassembling. Lens surface has anti-reflective film, anti-reflective film is afraid of pollution, fear of moisture, fear of oil, fear of scraping, so it is required to provide dry, oiled air in the work.
When cleaning the lens, you should wear gloves or special covers. Do not handle the lens directly with your hands, as it will cause permanent damage to the lens surface once it is stained with skin grease. For smaller lenses, it is more convenient to use optical tweezers or vacuum tweezers. Be careful when clamping the lens only along non-optical surfaces, such as the frosted edges of the lens.
1. Loosen the fastening screw, remove the air nozzle and lens tube in turn, and blow off the dust on the lens surface with a balloon first;
2. Use lab-grade soft paper cotton ball, dip in acetone or high purity alcohol, and gently rub it clockwise from the center of the lens to the edge. When necessary, both sides of the lens need to clean, scrub to be careful and meticulous;
3. Install the tube and nozzle, adjust the focal length, and tighten the screws.
In general, before and after the use and cleaning need to check the laser cutting machine focusing mirror. Because the surface defects of most contaminants are small in size, magnifying devices are often used when examining lenses. In addition to amplifying equipment, it is sometimes necessary to shine a relatively bright light on the optical surface to enhance the reflection of surface contaminants and defects in the mirror so that they can be found more easily.
The focusing lens of the laser cutting machine belongs to the consumable product, if it is still not high cleanliness after cleaning for many times, it is necessary to replace it, so as to ensure the processing efficiency of the laser cutting machine and ensure production.
