Laser cutting machines can be seen in metal processing factories. They have powerful functions and can perform flexible cutting of various metal materials. Here are some main functions of laser cutting machines. With these practical functions, it can greatly improve processing efficiency and Cutting performance, its main functions can be summarized as follows:
1. leapfrog
Leap of frog is the free-range method of laser cutting machine. The trajectory of the free-range motion of the cutting head is like an arc drawn by frog jumping, which is called leap-frog.
In the development process of laser cutting machine, leapfrog can be regarded as a prominent technological progress. The leapfrog action only takes up the translation time from point A to point B, saving the time of rising and falling. The frog jumps and catches food; the leap frog of the laser cutting machine "catches" high efficiency. If the laser cutting machine does not have the leapfrog function now, I am afraid it will not enter the stream.
2. Auto focus
When cutting different materials, the focus of the laser beam is required to fall on different positions of the workpiece section.
With the automatic focusing function, the processing efficiency of the laser cutting machine can be significantly improved: the perforation time of thick plates is greatly reduced; when processing workpieces of different materials and thicknesses, the machine can automatically quickly adjust the focus to the most suitable position.
3. Automatic edge finding
When the sheet is placed on the table, if it is skewed, it may cause waste when cutting. If the inclination angle and origin of the sheet can be sensed, the cutting process can be adjusted to suit the angle and position of the sheet, thereby avoiding waste. The automatic edge finding function came into being.
Thanks to the automatic edge-finding function, the time for adjusting workpieces earlier - adjusting (moving) workpieces weighing hundreds of kilograms on the cutting table is not an easy task, increasing the efficiency of the machine.
4. Concentrated perforation
Concentrated piercing, also known as pre-piercing, is a machining process, not a function of the machine itself. When laser cutting thicker plates, the cutting process of each contour goes through two stages: 1. perforation, 2. cutting.
Concentrated perforation avoids overburning. In the process of perforating thick plates, heat accumulation is formed around the perforation point, and if it is cut immediately, over-burning will occur. By adopting the centralized perforation process, when all perforations are completed and the cutting is returned to the starting point, the over-burning phenomenon is avoided due to sufficient time to dissipate heat.
5. Bridge bit (micro connection)
During the laser cutting process, the sheet is supported by serrated support bars. If the cut part is not small enough to fall from the gap of the support bar; if it is not big enough to be supported by the support bar, it may lose its balance and warp. The high-speed moving cutting head may collide with it, resulting in shutdown or damage to the cutting head.
Bridges connect parts with surrounding materials, and mature programming software can automatically add an appropriate number of bridges according to the length of the contour. It can also distinguish the inner and outer contours, and decide whether to add a bridge position, so that the inner contour (waste) of the bridge position will fall off, and the outer contour (part) of the bridge position will be adhered to the base material and will not fall off, thereby eliminating the need for Sorting work.
6. Common edge cutting
If the contours of adjacent parts are straight lines and have the same angle, they can be combined into one straight line and only cut once. This is a common edge cut. Obviously, common edge cutting reduces the cutting length, which can significantly improve the processing efficiency.
Edge cutting not only saves cutting time, but also reduces the number of perforations, so the benefits are very obvious. If 1.5 hours are saved every day due to common edge cutting, about 500 hours are saved every year, and the comprehensive cost per hour is calculated at 100 $, which is equivalent to an additional benefit of 50,000 $ a year. Co-edge cutting needs to rely on intelligent automatic programming software.
