Types of laser cutting machines and points of attention in typesetting

Author: Nanjing full-Rui Technology Published: 2019-09-02 18:17 views:
Before using the laser cutting machine , we will import the prepared drawings into the program, and then use the typesetting software to arrange the graphics on a board, so that the laser cutting machine can batch process the products. Among them, although the typesetting process is short, there is a lot of knowledge hidden in it. If the typesetting is wrong, it will greatly affect the cutting effect of the entire board. So, do you know what types of laser cutting machines are available? And are there any points to note in typography?

Note on typography:
1. Corner melting:
When cutting the corners of the steel sheet at a reduced speed, the laser will melt the corners due to overheating.
Generate a small radius at the corners to maintain high-speed laser cutting and avoid overheating and melting of the steel plate when cutting the corners;
So as to obtain good cutting quality, reduce cutting time and improve productivity.
2. Spacing of parts:
In general, cut thick plates and hot plates with a large distance between parts;
Because the heat of the hot plate of the thick plate has a greater influence, when cutting corners and small graphics, it is easy to burn edges and affect the cutting quality.
3. Lead setting:
In the process of cutting thicker plates, in order to make the cutting seam join well, prevent the beginning and end burns;
Often, a transition line is introduced at the beginning and end of the cut, which is called the lead and the tail respectively;

Leads and tail wires are useless to the workpiece itself, so it should be arranged outside the scope of the workpiece, and at the same time, pay attention not to set the leads at places that are difficult to dissipate heat such as sharp corners.
As far as possible, the arc is connected to the lead and the slit to make the machine move smoothly and avoid burns caused by the corner stop.
4. Common edge cutting:
Co-edge two or more parts into a combination, and try to co-edge large-scale regular graphics;
Co-edge cutting can greatly reduce cutting time and save raw materials.
5. Parts collision:
In order to maximize production efficiency, many laser cutting equipment are continuously running for 24 hours and use unmanned automatic loading / unloading equipment;
Hitting the overturned part after cutting caused damage to the cutting head and production interruption, resulting in greater losses.
This requires attention when sorting:
① Choose a suitable cutting path and detour the cut parts to reduce collisions.
② Choose the best cutting route and reduce the cutting time.
③ Automatically or manually combine multiple small parts with micro connections. After cutting, the removed parts can easily disconnect the micro connections.
6. Surplus material processing:
After cutting the parts, the skeleton-shaped residual material on the workbench of the laser cutting equipment needs to be removed as soon as possible to facilitate subsequent cutting operations.
For laser cutting equipment without an automatic unloading device, the skeleton-shaped residual material can be cut into small pieces to facilitate rapid removal.
Therefore, the operator can avoid personal injury caused by moving heavy and sharp-edged surplus materials.
Cutting machine type:
The first: CO2 laser cutting machine.
The main advantage:
High power, general power is between 2000-4000W, can cut full size stainless steel, carbon steel and other conventional materials within 25 mm;
And aluminum plate up to 4 mm and acrylic plate up to 60 mm, wood material board, PVC board, and the speed is very fast when cutting thin plates.
In addition, because the CO2 laser outputs a continuous laser, it is the smoothest and best cutting section of these three laser cutting machines when cutting.
Main market positioning:
6-25 mm cutting of medium and thick plates, mainly for large and medium-sized enterprises and some laser cutting processing enterprises that are purely external processing;
However, due to the large maintenance loss of its laser and the large power consumption of the host, it cannot be overcome;
In recent years, due to the huge impact of fiber laser cutting machines, the market is shrinking significantly.
The second type: YAG (solid) laser cutting machine.
The main advantage:
It can cut aluminum plates, copper plates and most non-ferrous metal materials that other laser cutting machines cannot cut. The machine is cheap to purchase, low to use, and easy to maintain;
Most of the key technologies have been mastered by domestic enterprises, the price of parts and maintenance is low, the operation and maintenance of the machine are simple, and the quality of workers is not high.
Main market positioning:
Cutting below 8mm, mainly for self-use small and medium-sized enterprises and most sheet metal manufacturing, home appliance manufacturing, kitchenware manufacturing, decoration and decoration, advertising and other industry users who are not particularly demanding in processing;
Gradually replace traditional processing equipment such as wire cutting, CNC punching, water cutting, and low-power plasma.
The third type: fiber laser cutting machine.
The main advantage:
High photoelectric conversion rate, low power consumption, can cut stainless steel plates and carbon steel plates within 12MM;
It is the fastest laser cutting machine among these three machines for cutting thin plates. The slit is small and the light spot quality is good. It can be used for fine cutting.
Main market positioning:
Cutting below 12mm, especially for high-precision machining of thin plates, is mainly aimed at manufacturers with extremely high requirements for accuracy and efficiency;
It is estimated that with the advent of 4000W and above lasers, fiber laser cutting machines will eventually replace most markets for CO2 high-power laser cutting machines.
