27-09-2016 Different industries laser engraving machine market to buy the skill of laser engraving machine products are various, there is the whole imported machines, domestic self-designed production machinery, import of machinery parts assembled in China, a professional engraving machine, there is professional marking machine, cutting machine a professional, who is also the function of two or more machines, then how to buy it 1) service:? laser engraving machine laser tube, reflective lenses are consumables, have a certain use life and need to be replaced after the expiration. This requires manufacturers to provide a strong after-sales service guarantee, can provide these supplies timely. 2) The product quality is also a laser engraving machine, the components used are different, the following examples: a) Stepper motor: related to the engraving precision of the laser engraving machine, some manufacturers choose the imported stepper motor, Some are stepper motors produced by joint ventures, and some are brand-name motors. b) Laser lens: related to the power of the laser engraving machine, divided into imported lenses, domestic lenses, domestic lenses are also divided into two types of imported materials and domestically produced materials, the price difference is very large, the use effect and service life also a great gap. c) Laser tube: This is the heart of the laser engraving machine. Because the price of imported laser tubes is expensive, generally tens of thousands of yuan, so most domestic laser engraving machines use domestic laser tubes. Domestic laser tubes are also uneven, and the price gap is very large. A good laser tube life is generally around 3,000 hours. d) Mechanical assembly quality: In order to reduce the cost, some manufacturers use a very thin iron sheet to make the machine casing. The user generally does not see it, but after a long time, the frame will be deformed, which affects the engraving precision of the laser engraving machine. A good laser engra
