Fiber laser cutting machine has been widely used in various manufacturing and processing industries because of its fast cutting speed, high efficiency and good cutting effect. On the one hand: the processing efficiency has been greatly improved; on the other hand: it has promoted the process of manufacturing intelligence and automation. From the strategic point of view of the current development, it has gradually replaced traditional cutting processing methods. In fact, in the process of using the laser cutting machine, we can cooperate with the following six practical tips to greatly improve the processing efficiency and cutting performance of the laser cutting machine. Let’s share with you Leapion Laser below.
Leapfrogging is the idle way of laser cutting machines. In the development process of the laser cutting machine, the leapfrog can be regarded as an outstanding technological advancement. Leapfrogging only takes up the translational time from point A to point B, and saves the time of ascent and descent. The frog jumped and caught the food; the frog jump of the laser cutting machine "caught" high efficiency. If the laser cutting machine does not have the leapfrog function, I am afraid it will not enter the market.
Empty distance, commonly known as "empty run". After cutting hole 1, then hole 2 is to be cut. The cutting head must move from point A to point B. Of course, the laser must be turned off during the movement. The movement process from point A to point B, the machine runs "empty", which is called idling.
When cutting different materials, the focus of the laser beam is required to fall at different positions on the cross-section of the workpiece. Therefore, it is necessary to adjust the position of the focus (focus). Early laser cutting machines generally used manual focusing; now, many manufacturers' machines have achieved automatic focusing.
The method of automatic focusing is: before the beam enters the focusing mirror, a variable curvature mirror (or adjustable mirror) is set, and the divergence angle of the reflected beam is changed by changing the curvature of the mirror, thereby changing the focus position. This function can help the machine automatically adjust the focus to the most suitable position quickly.
The automatic edge finding function can sense the inclination angle and origin of the sheet, and adjust the cutting process to suit the angle and position of the sheet, thereby avoiding waste. With the help of the automatic edge finding function, it saves the time of adjusting the workpiece earlier-it is not easy to adjust (move) workpieces weighing hundreds of kilograms on the cutting table, which improves the efficiency of the machine.
Centralized perforation, also known as pre-perforation, is a processing technology, not a function of the machine itself. It needs the help of an automatic programming system when it is used. When laser cutting thicker plates, each contour cutting process has to go through two stages: 1. perforation and 2. cutting.
Centralized perforation can improve processing efficiency. By adopting the centralized perforation method, you can first adjust the focus to a position suitable for perforation. After the perforation is completed, stop the machine, and then adjust the focus position to the best position required for cutting; in this way, the perforation time can be shortened by more than half, greatly Improve efficiency.
It is also possible to adjust or change other process parameters between concentrated piercing and cutting (for example, air + continuous wave can be used for piercing, and oxygen can be used for cutting, and there is enough time to complete the gas switch).
During the laser cutting process, the sheet material is supported by the serrated support bar. If the cut part is not small enough, it cannot fall from the gap of the support bar; if it is not large enough, it cannot be supported by the support bar; it may lose its balance and warp. The cutting head moving at high speed may collide with it, in the slightest it will stop, and in the worst case it will damage the cutting head.
This phenomenon can be avoided by using the bridge position (micro-connection) cutting process. When programming the graphics for laser cutting, the closed contour is intentionally broken in several places, so that the parts and the surrounding materials will stick together after the cutting is completed, so that they will not fall. These broken places are the bridges. Also called breakpoints, or micro-connections. The distance of the break, about 0.2～1mm, is inversely proportional to the thickness of the sheet. Based on different angles, there are these different names: based on the contour, it is disconnected, so it is called the breakpoint; based on the part, it is adhered to the base material, so it is called the bridge or micro-connection.
The bridge position connects the parts with the surrounding materials, and the mature programming software can automatically add an appropriate number of bridge positions according to the length of the contour. It can also distinguish the inner and outer contours and decide whether to add bridges, so that the inner contours (waste) that do not leave the bridges will fall, and the outer contours (parts) of the bridges will be glued together with the base material and will not fall, thus avoiding Sorting work.
If the contours of adjacent parts are straight lines and the angles are the same, they can be merged into a straight line and only cut once. This is the common edge cutting. Obviously, co-edge cutting reduces the cutting length, and co-edge cutting does not require the shape of the part to be rectangular. Therefore, the processing efficiency is greatly improved.
Note: Co-edge cutting does not require the shape of the part to be rectangular.
The above are six coups that can improve the processing efficiency of fiber laser cutting machine. If we use these six functions reasonably, we can play more and more functions of fiber laser cutting machine.
