Operation and maintenance of water jet cutter

Due to the excellence of water jet cutting technology, it has become a widely used cutting technology, so the corresponding equipment water jet cutting machine has also been favored by many users. However, the problem now is how to select a water cutting machine that can meet the actual processing requirements. 

Due to different working conditions, the corresponding waterjet cutting parameters are also different, so we will start from this aspect and make analysis one by one. The important parts of the water jet cutting machine mainly involved include its CNC working platform, high-pressure system and other optional items, which should be taken into account in each environment.

1. CNC  water jet cutting machine

The CNC waterjet cutting equipment mainly includes cantilever type and gantry type. The advantage of the former is that its halo mechanism is separated from the cutting platform, which will not affect each other. It is very suitable for irregular material size and unfixed loading and unloading methods; The latter is just the opposite.

It can be seen that which one to choose depends on the size of the cutting material. If you purchase equipment mainly to undertake external cutting, the cantilever CNC cutting platform can meet the requirements.

2. High pressure system of water jet cutting machine

This is also closely related to the cutting materials, mainly depending on the material type, thickness, cutting surface quality and requirements for cutting speed. For example, the 300 MPa high-pressure system can be used for cutting hard materials with a thickness of less than 30 mm; If the material hardness ratio is high, 380 MPa high pressure system can be selected, mainly because of its advantages in cutting capacity, cutting surface quality, cutting speed, etc.

3. Other optional items of water jet cutting machine

In addition to the two items mentioned above, the soft water treatment and automatic sand feeding system of the water cutting machine are also important, and none of them can be ignored.

Those who know something about water jet cutter should know that it can cut well no matter what material it is, metal or non-metal, natural or artificial, production supplies or daily necessities. However, compared with other cutting equipment, the working site and working environment of the water jet cutter are relatively poor, which will produce relatively large metal dust. Therefore, in order to ensure the normal operation of the equipment, maintenance and repair work must be carried out. The details of how to operate are as follows.

The water jet cutter is also a kind of relatively precise equipment, so the requirements for operators are also relatively high. It must be professionally trained, and the operating skills of the equipment can be mastered. Before being officially put into operation, it must be ensured that there is no external interference, and the materials to be cut cannot exceed the specified cutting range.

Generally, the maintenance of water jet cutter is carried out regularly, including daily, weekly and monthly. The regulations are as follows:

1. Daily maintenance

Relevant personnel shall clean the equipment every day after finishing processing to keep the machine tool and guide rail clean; Pay attention to whether the power and air supply are turned off; If there is residual gas in the pipe belt of the cutting machine, it should also be emptied; If the machine is not used for a long period of time, turn off the power in time; Pay attention to whether the horizontal and vertical guide rails and rack surfaces are well lubricated.

2. Weekly maintenance

In fact, they are almost the same, that is, if the horizontal and vertical rail wipers of the water jet cutter are abnormal, they should be replaced with new ones in time; The cutting torch is loose, and the garbage at the ignition gun mouth and the automatic height adjusting device should be paid attention to.

3. Monthly maintenance

It is a summary of the daily and weekly maintenance work of the water jet cutter and a complete inspection of the whole equipment. No spare parts can be missed
