The cutting capability of waterjet cutting technology on steel plates has always been one of the focal points of attention. In fact, the cutting depth and cutting speed of waterjet cutting technology depend on the hardness and thickness of the material being cut. For thick steel plates, the cutting capability of waterjet cutting is subject to certain limitations.
Firstly, the thickness of the steel plate affects both the cutting depth and cutting speed of waterjet cutting. Generally, the cutting depth achievable with waterjet cutting is about 150mm, and as the thickness of the material being cut increases, the cutting speed slows down and the cutting depth becomes shallower. Therefore, when using waterjet cutting on thick steel plates, the influence of cutting depth and cutting speed needs to be considered, and it may be necessary to perform multiple cuts or adopt other cutting methods.
Secondly, the hardness of the steel plate also affects the cutting capability of waterjet cutting. Typically, waterjet cutting is suitable for materials with lower hardness, such as aluminum, copper, and plastics. However, for high-hardness steel, the effectiveness of waterjet cutting decreases, and the cutting speed slows down. Therefore, when using waterjet cutting on steel plates, it is necessary to assess the hardness of the steel plate and select appropriate cutting parameters and methods.
In summary, there are certain limitations to waterjet cutting when cutting thick steel plates, and it is necessary to choose appropriate cutting parameters and methods based on the hardness and thickness of the material being cut. For thick steel plates that exceed the depth limit of waterjet cutting, other cutting methods such as laser cutting, plasma cutting, or oxy-fuel cutting can be considered.
