Information

In recent years, laser cutting machine has been playing an increasingly important role in the development of sheet metal industry.In the process of cutting, there are six practical functions, with these practical functions, can greatly improve the laser cutting machine processing efficiency and cutting performance.

 

 

1. The leapfrog

 

The leapfrog is the air way of laser cutting machine.As shown in the figure below, cut hole 1, then cut hole 2.The cutting head should be moved from point A to point B.Of course, turn off the laser as you move.The movement process from point A to point B, the machine "empty" run, called empty distance.

 

The blank range of the early laser cutting machine is shown in the figure below. The cutting head has to complete three actions: rise (to a safe enough height), translation (to reach the top of point B), and descent.

 

 

Compressed air time can improve the efficiency of the machine.If the three actions completed in the second time are changed into "simultaneous", the free time can be shortened: when the cutting head moves from point A to point B, it rises simultaneously;As we approach point B, we go down at the same time.As shown in the figure below.

 

 

Cut the trajectory of head - to - air movement, like a frog jump by drawing an arc.

 

In the development of laser cutting machine, leapfrog is a prominent technological advance.The frog jump only takes up the translational time from point A to point B, and saves the time of going up and down.The frog jumps and catches the food;Laser cutting machine leapfrog, "capture" to high efficiency.If the laser cutting machine does not now have the function of leapfrog, I am afraid it will not flow.

 

2. Auto focus

 

When cutting different materials, the focus of the laser beam is required to fall at different positions of the workpiece section.Therefore, you need to adjust the focus position (focus).Early laser cutting machine, the general use of manual focus;Today, many manufacturers have automatic focus on their machines.

 

One might say, just change the height of the cutting head. If the cutting head goes up, the focus will be high. If the cutting head goes down, the focus will be low.It's not that simple.

 

In fact, in the process of cutting, the distance between the nozzle and the workpiece (the height of the nozzle) is about 0.5 ~ 1.5mm, which may be considered as a fixed value, that is, the height of the nozzle remains unchanged, so it is not possible to adjust the focus by lifting the cutting head (otherwise the cutting processing cannot be completed).
