Guide for Winter Antifreeze of Laser Equipment

As winter comes, the temperature drops sharply. In order to better protect the laser and ensure the normal operation of the laser in winter, we hereby remind all partners and users to take anti freezing measures for the laser in winter. 1. Since the laser equipment uses water as the cooling medium, the operating ambient temperature of the laser should be above 5 ℃. 2. In winter, if there is no heating in the workshop, or the ambient temperature may be lower than 5 ℃. If the laser does not work at night or on weekends, the machine tool can still be turned on. In this way, the cooling water is still in circulation and will not freeze. 3. If your factory or workshop has a long holiday and the machine tool is not running during the holiday period. Be sure to pay attention to the thermal insulation treatment of the machine tool in winter. The water of the chiller, the laser, the cutting head and the lens must be drained to prevent the damage of the machine tool caused by icing. Basic principles and methods of antifreeze All liquids have a "freezing point". When the liquid temperature is lower than this "freezing point", it will solidify to form a solid, while the volume of deionized water or purified water will become larger during the solidification process, which will "support" the pipeline and sealing connection of the water cooling system and cause damage. In order to avoid damage to the laser, output head and water cooler caused by solidification of cooling liquid, there are three solutions: 1. If there is no power failure in the local area, do not turn off the water cooler at night to ensure that the coolant is in circulation and the temperature is not lower than the freezing point. 2. Drain the cooling liquid in the laser, laser output head and water cooler after use every day. 3. Use proper antifreeze as coolant. Note: Any antifreeze cannot completely replace deionized water and cannot be used for a long time all year round. After winter, the pipeline must be cleaned with deionized water or purified water, and the use of deionized water or purified water as coolant must be resumed.

    3000W Laser Cleaning Machine Helps Open Customers' Cleaning Service Business

    Laser cleaning is a new type of cleaning process, which has a good effect on metal surface treatment and high efficiency. With the background of carbon neutrality and carbon peak, green laser cleaning will open its market. On July 27th, a 3000W laser cleaning machine is about to be sent to the UK to help the customer start his laser cleaning service business. This client will do business in the following businesses. Laser cleaning in the tire industry mainly cleans tire molds; laser cleaning machines in the manufacturing industry are mainly used to clean workpieces, rust layers, paint, oil stains on the surface of equipment, etc., and can also be used to clean welded parts, which are very good before and after welding. In terms of bridge construction, it is used to clean the rust layer on the surface of the bridge steel structure; in railway transportation, it is used to clean the rust layer of the rail, the paint layer of the high-speed rail car, and the cleaning of the air conditioners; the shipbuilding industry can be used to clean the rust layer of the ship board Oxidation color cleaning on the surface of welding parts, etc.

    Maintenance of Laser Equipment in Summer

    With the arrival of summer, the temperature rises and the air humidity is high, and the maintenance of the laser cutting machine also needs to be paid attention to. Duman laser professional after-sales engineers teach you 6 steps to easily get summer equipment maintenance skills, let's take a look! Water cooler cleaning In summer, the water temperature is set, the low temperature water is set at about 26°C, and the normal temperature water is set at about 30°C. Change distilled or purified water every two weeks, and clean the water filter and water tank. Clean the air filter and condenser every one to two days. Laser Maintenance In the high temperature environment in summer, the laser should be equipped with an air-conditioned room, and the air-conditioning temperature should be set to dehumidification mode with a constant temperature of 26°C. Oil tank level Check the oil level of the oiler every week. The automatic lubrication system will automatically alarm when the oil level is too low. Please use Mobil 46# lubricating oil to refill the oil to the highest level. Mechanical cleaning When the equipment is powered off, clean the Y-axis, X-axis, and Z-axis rail racks every week, and apply lubricating oil in time after cleaning. Maintenance of distribution box When the equipment is powered off, clean the dust in the distribution box with clean compressed air every week, check the line connections, and eliminate potential safety hazards in time. IPC Maintenance Clean the industrial computer every 6 months, remove the fixing bolts, and take off the cover to clean the motion control card and memory module. Gold thumb keys for memory sticks. The above is about the maintenance of the laser equipment in summer. Hope it will be helpful to users who are using laser equipment for processing.
