The current laser cutting machines are high-power heavy-duty equipment. Its good performance makes the subsequent work smoother and reduces costs. So, let's see how to maintain these guys and keep them in good condition.
1. The cooling system should be grounded, and the water tank and water circuit are often cleaned. The temperature control point of the cooling temperature control water tank should be appropriate, otherwise the laser tube will be damaged and dew condensation, and the power will be reduced. The cold water head falls off, the life is greatly shortened, and sometimes it can not work, resulting in continuous pipe replacement.
2. The fulcrum of the laser tube installation of the laser cutting machine should be reasonable. The fulcrum should be 1/4 of the total length of the laser tube, otherwise the spot pattern of the laser tube will be deteriorated, and sometimes the spot will become several points within a period of time, causing the laser The power reduction cannot meet the requirements.
3. Water protection should always be inspected and cleaned. Cooling water often cannot be washed away from the water protection float switch or the water protection float switch is not reset, and short-circuiting methods cannot be used to solve the problem.
4. The suction device should be checked and cleaned as scheduled, and the fan duct should be cleaned. Otherwise, a lot of smoke and dust cannot be discharged, which quickly contaminates the lens and the laser tube, so that the mechanical and electronic parts are easily oxidized and cause poor contact.
5, focus lens and reflector inspection, the lens frame will become hot after work, the lens surface will become discolored and rusty; peeling and cracking are all objects to be replaced, especially many customers use air pumps and air compressors, so focus lenses Because of the accumulation of water on the surface, it is necessary to regularly ensure the cleanliness and quality of the lenses in the optical path system.
6. The working environment of the laser cutting machine must not be too harsh. If the ambient temperature is higher than 30 degrees and lower than 18 degrees, there is too much dust and serious air pollution, so the machine will be damaged, and the failure rate will continue to rise; all electrical parts in a humid environment It's easy to go wrong.
7, the power grid power needs to match.
8. The working current of the laser tube should be reasonable and cannot work at full power for a long time; the laser should be reasonably applied and the laser energy should be saved; the optical path system should be cleaned regularly, otherwise the laser tube will age and rupture prematurely, and the power of the laser device should be adjusted during operation 50-60% of the total power, and then adjust the working speed according to the material, this is the best working state of the laser tube.
