三.水保护系统应定期进行检查和清洗，建议只用纯净水等直饮水，否则使用一段时间之后会出现水垢，且破坏零部件，造成无法冲开保护浮子开关，直接影响激光雕刻机的使用；<br><br>四.吸风装置应定期做检查和清理，长期不进行清理容易出现灰尘排不出，影响设备的清洁，干扰镜片和激光管的工作，并且灰尘容易造成机械零部件的接触不良；<br><br>五.聚焦镜和反光镜需每天进行检查，且长时间连续工作的情况下，镜架发烫容易引起镜片表面变色生锈，镀膜开裂等，这时候要更换配件了;且脱膜开裂是属于要更换的范围了，特别是一些客户会使用大气泵和空压机，这样在聚焦镜片上容易有积水产生，不及时处理会影响光路，进而影响激光雕刻机的正常使用；<br><br>六.激光雕刻机的工作环境也有一定的要求，建议在不高于30度不低于20度的情况下使用，且室内环境不能有太多灰尘，否则很容易对零部件产生影响，故障率也逐渐升高，且不易在潮湿或过度干燥的坏境中使用，这样对于机器的维护也有很大的影响;<br><br>七.用电功率要稳定，电器反复的不正确断电会影响到机器的使用寿命，并且经常出现高低压也会容易引起激光雕刻机的使用寿命；<br><br>八激光管的工作电流要合理，长期处于90-100光强下工作，不仅耗能大，也会导致光路系统使用过当，影响激光管的使用寿命，建议经常对激光管进行清洁，防止过早老化和破裂。建议激光雕刻机的光路调整在50-60，再根据雕刻材料进行速度调整，以便达到好的工作状态；<br><br><br>九.机器的稳定性一定要强，底板和凭条都要凭证，否则操作员在进行操作的时候对光路进行调整以便于穿透完成，这样的变焦容易引起激光管的老化；<br><br>十.激光雕刻机的激光电源的散热系统要灵活通畅，保障在工作的时候不会因为调整速度而引起的温度的上升而得不到及时的散热，诱发激光雕刻机的使用。

III The water protection system shall be inspected and cleaned regularly. It is recommended to only use direct drinking water such as purified water, otherwise scale will appear after use for a period of time, and the parts will be damaged, so that the protection float switch cannot be opened, which will directly affect the use of the laser engraving machine;<br>IV The air suction device shall be inspected and cleaned regularly. If it is not cleaned for a long time, it is likely that the dust will not be discharged, which will affect the cleaning of the equipment, interfere with the work of lenses and laser tubes, and the dust is likely to cause poor contact of mechanical parts;<br>V The focusing lens and reflector shall be inspected every day. When they work continuously for a long time, the lens frame is hot, which is easy to cause discoloration, rust and Coating Cracking on the lens surface. At this time, the accessories shall be replaced; In addition, the film peeling and cracking belong to the scope to be replaced. In particular, some customers will use the atmospheric pump and air compressor, so it is easy to accumulate water on the focusing lens. If it is not handled in time, it will affect the optical path, and then affect the normal use of the laser engraving machine;<br>Vi The working environment of the laser engraving machine also has certain requirements. It is recommended to use it at no more than 30 degrees and no less than 20 degrees, and there should not be too much dust in the indoor environment, otherwise it is easy to affect the parts, the failure rate increases gradually, and it is not easy to use it in a wet or excessively dry environment, which also has a great impact on the maintenance of the machine;<br>VII The power consumption should be stable. Repeated incorrect power failure of electrical appliances will affect the service life of the machine, and frequent high and low voltage will easily lead to the service life of the laser engraving machine;<br>VIII. The working current of the laser tube should be reasonable. Working at 90-100 light intensity for a long time will not only consume a lot of energy, but also lead to excessive use of the optical path system and affect the service life of the laser tube. It is recommended to clean the laser tube frequently to prevent premature aging and rupture. It is suggested that the optical path of the laser engraving machine should be adjusted at 50-60, and then the speed should be adjusted according to the engraving materials, so as to achieve a good working state;<br>IX The stability of the machine must be strong, and the bottom plate and voucher must be certified. Otherwise, the operator will adjust the optical path during operation to facilitate penetration. Such zoom is easy to cause the aging of the laser tube;<br>X The heat dissipation system of the laser power supply of the laser engraving machine shall be flexible and unobstructed to ensure that the temperature rise caused by adjusting the speed will not lead to timely heat dissipation and induce the use of the laser engraving machine.

3. The water protection system should be inspected and cleaned regularly. It is recommended to use only pure water and other direct drinking water, otherwise scale will appear after a period of use, and parts will be damaged, which will make it impossible to open the protection float switch and directly affect the use of the laser engraving machine. 4. The air suction device should be inspected and cleaned regularly. If it is not cleaned for a long time, it will easily lead to dust discharge, which will affect the cleaning of equipment and interfere with the work of lenses and laser tubes, and dust will easily cause poor contact of mechanical parts; 5. The focusing mirror and reflector should be inspected every day, and if they work continuously for a long time, the burning of the frame will easily cause discoloration, rust and coating cracking on the lens surface, etc. At this time, the accessories should be replaced; And the peeling cracking belongs to the scope to be replaced, especially some customers will use air pump and air compressor, so that water accumulation is easy to occur on the focusing lens, and failure to deal with it in time will affect the light path, thus affecting the normal use of the laser engraving machine. 6. The working environment of laser engraving machine also has certain requirements. It is recommended to use it at a temperature not higher than 30 degrees and not lower than 20 degrees, and the indoor environment should not have too much dust, otherwise it will easily affect parts and components, and the failure rate will gradually increase, and it is not easy to use it in humid or over-dry environment, which will also have great influence on the maintenance of the machine. 7. The power consumption should be stable. Repeated incorrect power cuts of electrical appliances will affect the service life of the machine, and frequent high and low voltage will easily lead to the service life of the laser engraving machine. The working current of the eight laser tubes should be reasonable. Working at 90-100 light intensity for a long time will not only consume a lot of energy, but also lead to overuse of the optical system, which will affect the service life of the laser tubes. It is recommended to clean the laser tubes frequently to prevent premature aging and cracking. It is suggested that the light path of the laser engraving machine should be adjusted at 50-60, and then the speed should be adjusted according to the engraving materials in order to achieve a good working condition. 9. The stability of the machine must be strong, and both the base plate and the receipt should be certified, otherwise, the operator will adjust the light path to facilitate the penetration, and such zooming will easily cause the aging of the laser tube; 10. The heat dissipation system of the laser power supply of the laser engraving machine should be flexible and smooth, so as to ensure that the heat dissipation will not be timely caused by the temperature rise caused by adjusting the speed when working, which will induce the use of the laser engraving machine.
