In terms of economy, the cost and price of water cutting machine are not low because of its complexity. The cutting cost per unit processing task is large, and the cutting speed must not be the highest. Therefore, water cutting is not the best choice in terms of reducing cost or pursuing speed.
Process adaptability. In addition to the smaller diameter DIN 1628 ST52.4 steel pipe (no more than 50mm) or steel bar (no more than 100mm), when cutting with a water knife, the DIN 1628 ST52.4 steel pipe or steel bar must be rotated evenly before cutting. Moreover, in order not to damage the inner wall of the DIN 1628 ST52.4 steel pipe, other measures must be taken. When cutting the steel bar, it must also be three-axis linkage. This determines that such a water cutting machine is more complex.
To sum up, the selection order of several cutting machines for cutting DIN 1628 ST52.4 steel pipe or steel bar should be: disc cutting machine, flame / plasma cutting machine, laser cutting machine and water knife cutting machine.
