Some users found that the water jet cutting machine had problems just after they bought it and used it for a few days. Some people thought it was a quality problem of the water jet cutting machine. In fact, there are generally two reasons for this situation. One is that the water jet cutting machine manufactured by the manufacturer does not meet the standards; the other is that the water jet cutting machine is used improperly during the running-in period.
The running-in period is an important link to ensure the normal operation of the water jet cutting machine, reduce the failure rate, and extend its service life. Many people do not pay much attention to the special requirements of using the water jet cutting machine during this period, and use it overloaded for a long time, resulting in frequent failures of the cutting machine in the early use. Newly assembled parts have deviations in geometric shape and matching dimensions. In the early stage of use, due to alternating loads such as impact and vibration, as well as factors such as heat and deformation, coupled with excessive wear and other reasons, it is easy to loosen the originally fastened parts. Because the matching clearance of the newly assembled parts is small, and due to assembly and other reasons, it is difficult to ensure the uniformity of the matching clearance, and the lubricating oil is not easy to form a uniform oil film on the friction surface to prevent wear. This reduces the lubrication efficiency and causes abnormal wear of the water jet in the early stage. In severe cases, it will cause scratches or bites on the friction surface of the precision match, leading to the occurrence of failures.
Just as you need to be more careful about the speed and maintenance of a car during the running-in period than in normal times, the same is true for water jet cutting machine. Due to insufficient understanding of the structure and performance of the machine (especially for new operators), it is easy to cause malfunctions due to operating errors, or even mechanical accidents. During this period, the maintenance of the water jet cutting machine must be done according to the manufacturer's requirements. During the running-in period of the water jet cutting machine, try not to use the maximum pressure for cutting processing, and try to keep the running-in period as long as possible. Don't be impatient to start the machine and want to recover your investment very urgently. During the use of the water jet cutting machine, pay more attention to the various reactions that occur during the water cutting process, and deal with some minor problems in time.
Another reason is the production of the water jet cutting machine manufacturer itself. This requires friends to have some understanding of the manufacturer's reputation and machine performance when purchasing a water jet cutting machine, and don't pursue price too much.
