The main advantages of
laser and plasma cutting are good cutting performance, small heat affected zone and low heat input. These two cutting processes can also cut very small workpieces, flakes and sieve plates without deforming them, nor reducing their hardness, and preheating can be omitted.
The ideal steel plate surface is the basic prerequisite for laser cutting, because the laser beam must be concentrated without reflection loss, and be completely absorbed by the condensing point on the surface of the steel plate without interference.
If required,
all wear-resistant steels can be supplied after shot blasting and coating. Cutting performance largely depends on the laser energy and the thickness of the steel plate being cut. The thickness of the steel plate is 10mm, the laser energy is 2-3KW, and the maximum cutting speed can reach 2000mm/min.
It is possible to improve this performance with proper surface treatment (such as the use of emulsifiers).
Unlike laser cutting, plasma cutting is suitable for steel plates above 30mm, and the heat affected zone is slightly larger. Different cutting methods have typical effects on hardened
NM400, WearTuf450, Hardox500 wear-resistant steel. Wear-resistant plate waterjet cutting, this method is especially suitable for cutting wear-resistant steel. Because waterjet cutting has no thermal effect, it will neither cause material changes nor damage the performance of the workpiece, but the cutting speed is relatively slow.
