Waterjet cutting and milling
If you want to cut the periphery of the workpiece and punch holes, instead of using blind holes, drilling and threading methods, it is better to choose a sand cutter that is faster, easier to arrange and cheaper. The main reason is that we only need one water cutting process to complete the cutting of the workpiece, without having to grind all the metal into pieces. When it is necessary to cut high-precision workpieces, the sand knife is a machine tool that can be used to produce close to the finished product, which can be processed in one time without heat effect. In addition, the waste generated by the sanding knife is usually more valuable because it is in the form of a whole piece rather than scraps and can be reused.
How does waterjet cutting compare with arc and flame cutting?
Obviously, Plasma is a thermal processing process, which will produce a thermal effect on the finished product. However, the surface treatment of the sand knife is usually better, and there will be no scum on the back of the workpiece, which can reduce the secondary processing. Sand knife cutting has no thickness limitation, and the layout spacing of cutting graphics can be reduced to save material costs.
