12 Precautions for Correct Use of Laser Engraving Machines Laser engraving machines are also a type of laser marking machine. In the use and maintenance, we need to master the method and careful maintenance, in order to make the machine more stable and play its role. 1. The laser grounding machine's good grounding laser power supply and machine bed must have good grounding protection. The ground wire should be used with a dedicated ground wire of less than 4Ω. The necessity of grounding is: (1) to ensure the normal operation of the laser power supply, (2) to extend the life of the laser tube, (3) to prevent the machine from jumping due to external interference, and (4) to prevent the circuit damage caused by high-voltage discharge. 2. The cooling water of the laser engraving machine should be unblocked. Whether it is tap water or circulating water pump, the water flow must be kept clear. Cooling water is the heat generated by the laser tube. The higher the water temperature, the lower the light output power (15-20 °C water temperature is better); when the water is broken, the tube end will burst due to heat accumulated in the laser cavity, and even the laser will be damaged. power supply. Therefore, it is necessary to check whether the cooling water is unblocked at any time. When the water pipe has a hard fold (dead bend) or falls off, and the pump fails, it must be repaired in time to avoid power loss or even equipment damage. 3, cleaning and maintenance, good exhaust, clean the maintenance of the machine at any time, is a necessary condition for the normal operation of the machine. Imagine that the joints of people are not flexible, and how do they act? By the same token, the machine tool guide rail is a high-precision core component. After each work is completed, it must be wiped clean and kept clean and smooth. The bearings should also be oiled regularly, so that the drive can be flexible, the machining is accurate, and the service life of the machine tool is pr

Laser engraving machine is laser marker of one kind. On the need to master the use and maintenance methods and careful maintenance in order to make the machine more stable play its role.1, a good grounding laser power, laser engraving machine tool bed must have a good grounding protection, ground application is less than 4Ω dedicated ground. Necessity is grounded:(1) laser power can be guaranteed to work properly,(2) to extend the service life of laser tube,(3) to prevent outside interference caused by beating machine,(4) to prevent the accidental discharge caused by the high pressure circuit damage.2, the cooling water flow to the laser engraving machine, whether it be water or a circulating pump, water flow must be maintained. Cooling water is taken away by the heat generated by the laser tube, the higher the temperature, the lower the optical output power (the water temperature to 15-20 ℃ better); when the laser cavity without water due to heat build-up caused by burst pipe end, or

Shenhua will participate in the 120th China Import and Export Fair (Canton Fair) 2016, the 119th China Import and Export Fair, will be held on October 15-19, 2016 (5 days), in Guangzhou · China Import and Export Fair Zhangzhou Exhibition Hall was held. The booth number of our company is 1.1 Hall J17-J18. Welcome new and old customers to visit and guide. The Canton Fair, also known as the China Export Commodities Fair, was founded in the spring of 1957. It is held in Guangzhou every spring and autumn. It has a history of more than 40 years. It is the longest, highest level, largest and most comprehensive in China. A comprehensive international trade event with the largest number of merchants and the best results. Looking back, the Canton Fair broke through the blockade and opened up a channel for foreign exchanges for the new China. The first fair was held in the original Sino-Soviet Friendship Building in the spring of 1957. The exhibition hall covers an area of ​​18,000 square meters, 13 exhibiting trade groups, more than 12,000 exhibiting goods, and 1,223 visitors from 19 countries and regions attended the meeting and negotiated a deal of 17.54 million. Dollar. After 47 years, China's all-round opening to the outside world, the mission of the Canton Fair is the same, and the road to the world is getting wider and wider. Compared with the founding year, today's Canton Fair has a construction area of ​​more than 170,000 square meters, 48 ​​trade fairs, 10,000 exhibitors and more than 100,000 exhibits. It is currently the most comprehensive export commodity trade fair in China with the longest history, the highest level, the largest scale, the largest variety of goods and the best deal. Looking back at the development path of the Canton Fair in the past 47 years, we can see that the Canton Fair has undergone tremendous changes in all aspects. In the exhibition scale, participation in the main body of the exhibition, the attendees, the amount of transactions, the type
