To maintain the waterjet cutting machine, the maintenance personnel need to clean the equipment after the processing is completed every day, so that the machine tool and the guide rail are kept clean; the first thing to pay attention to is whether the power and air source are turned off; if the pipe of the cutting machine If there is still air in the belt, it needs to be emptied; if the machine is not used for a long time, it needs to be turned off in time; also pay attention to whether the lubrication of the horizontal and vertical guide rails and rack surfaces is good.
The waterjet cutting machine needs to be repaired every week. The waterjet cutting machine is a precision instrument. If the horizontal and vertical rail wipers of the waterjet cutting machine are abnormal, they must be replaced in time; the cutting torch is loose, The trash on the firing muzzle and the automatic height adjustment device are all places to be concerned about.
It is necessary to make a summary of the daily and weekly maintenance work of the waterjet cutting machine, and conduct a complete inspection of the entire equipment, and not let go of every part.
To check the waterjet cutting machine, we must first be familiar with the water jet from the nozzle of the waterjet cutting machine. Turn on the water flow at low pressure and observe. The water flow should be symmetrical, and its width generally depends on the type of nozzle used. The water flow of ruby and sapphire nozzles is generally slightly wider; the water flow of diamond nozzles is narrower and more continuous. If the water flow begins to widen, it means that the nozzle is damaged and should be replaced immediately. A damaged nozzle will cause internal damage to the cutting head.
In addition, it is necessary to check the cutting head regularly for signs of wear and damage. For example, if the mixing tube accidentally contacts the fixture, it will damage the nozzle nut and internal parts that keep the mixing tube aligned.
Check the system and keep it in good working condition, so as to make the waterjet cutting operation more effective and extend the service life of its components. Consumable parts of the sand conveying system, such as pipes and joints, need to be regularly inspected and replaced. Ensure that no parts of the sand conveying system below the bottom of the micro hopper are exposed to air.
