Some functions of laser cutting machines are very practical
Laser cutting machines can be seen in metal processing plants. Powerful and flexible for cutting various metal materials. The following describes several main functions of a laser cutting machine. With these practical functions, it can greatly improve machining efficiency and cutting performance. The main functions are summarized as follows:
1. Frog Jump: Jump is the empty stroke mode of the laser cutting machine. The trajectory of the empty stroke of the blade is like an arc that a frog jumps over, called a jump.
In the development of laser cutting machines, leapfrogging can be seen as a prominent technological progress. The frog jump action only takes up the translation time from point A to point B, saving time for ascent and descent. The frog jumped and caught the food. The leapfrog “capture” of laser cutting machines has resulted in high efficiency. If the laser cutting machine does not have the leapfrog function, it may not be popular.
2. Auto focus.
When cutting different materials, the focus of the laser beam is required to fall at different positions on the cross section of the workpiece.
Through the automatic focusing function, the processing efficiency of the laser cutting machine can be significantly improved: greatly reducing the perforation time of thick plates. When machining workpieces of different materials and thicknesses, this machine automatically and quickly adjusts 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 during cutting. If the inclination angle and origin of the sheet can be detected, the cutting process can be adjusted to accommodate the angle and position of the sheet, thereby avoiding waste. The automatic edge finding function emerged as the times require.
With the automatic edge finding function, it saves time to adjust the workpiece earlier. Adjusting (moving) a workpiece weighing hundreds of kilograms on the cutting table is not an easy task, and improves the working efficiency of the machine.
4. Concentrated perforation.
Centralized piercing, also known as pre piercing, is a processing technique, not a function of the machine itself. When laser cutting thicker plates, the cutting process for each contour goes through two stages: 1 Perforation, 2 Cut
Concentrated perforations can avoid over burning. During the perforation process of thick plates, heat accumulates near the perforation point, and if cut immediately, excessive burning will occur. Using a centralized punching process, when all punching is completed and the cutting returns to the starting point, there is sufficient time to dissipate heat to avoid overheating.
5. Bridge position (micro connection).
During laser cutting, the plate is supported by a serrated support rod. If the cut part is not small enough, it cannot fall through the gap of the support rod. If it is not large enough, it cannot be supported by a support rod. Otherwise, it may lose its balance and become tilted. High speed moving cutting heads may collide with them, which will at least cause the machine to stop, and in the worst case, damage to the cutting head.
The bridge connects the parts to the surrounding material. Mature programming software can automatically add an appropriate number of bridges based on the length of the contour. It can also distinguish between internal and external contours and decide whether to add a bridge, so that the inner contour (scrap) without the bridge will fall, while the outer contour (part) with the bridge will adhere to the substrate without falling, thereby eliminating the sorting task.
6. Common edge cutting.
If the contour lines of adjacent parts are straight lines at the same angle, they can be merged into a straight line, requiring only one cut. This is called co edge cutting. Obviously, ordinary edge cutting reduces the cutting length and can significantly improve machining efficiency.
Edge cutting not only saves cutting time, but also reduces the number of perforations, so the benefits are significant. If we save 1.5 hours per day due to common cutting, we can save about 500 hours per year, and the comprehensive cost per hour is calculated as 100 yuan, which is equivalent to creating 50000 yuan of benefits over a year. Common trimming requires intelligent automatic programming software.
