Laser cutting machine for cutting the focus of the different options
a, cutting focus on workpiece
when focus on the artifacts, also formed the negative focal length, the location is at the top of the cutting material. It is understood that. This way is mainly used for cutting, high thickness material for nozzle delivery problems such as lack of oxygen, the choice of this kind of focus tends to cut surface are relatively rough, is not suitable for high precision cutting.
2, cutting focus in workpiece
this way is known as the focal length, when a device artifacts are stainless steel or aluminum plate cutting, cutting points will often go on inside the workpiece, due to the focus principle of cutting surface, cut relatively bigger than cutting point on the workpiece surface, so this model needs to cut air flow is opposite bigger, temperature requirements are also higher, workpiece be perforated time consuming.
3, cutting focus on workpiece surface
zero distance means such as cutting, laser cutting machine to work focus is usually selected in close to the surface, this mode of workpiece surface smoothness is not the same, up and down based on past experience, the cut surface close to the focal point is relatively smooth, focus away from the cutting of the slightly rough surface. Relevant personage points out that this model should be according to the practical application of the technical requirements of the upper surface and under surface.
