Cautions when choosing a laser cutting machine

06.01.2020 22:58

 
The laser cutting machine focuses the laser light emitted from the laser into a high power density laser beam through the optical path system. The laser beam is irradiated to the surface of the workpiece, so that the workpiece reaches the melting point or boiling point, and the high-pressure gas coaxial with the beam blows away the molten or vaporized metal.
With the movement of the relative position of the beam and the workpiece, the material finally forms a slit, so as to achieve the purpose of cutting.
 
The laser cutting process replaces the traditional mechanical knife with an invisible light beam. It has the characteristics of high accuracy, fast cutting, not limited to cutting pattern restrictions, automatic typesetting to save materials, smooth cuts, and low processing costs. It will gradually improve or replace Traditional metal cutting process equipment. The mechanical part of the laser cutter head has no contact with the workpiece, and will not cause scratches on the workpiece surface during work. The laser cutting speed is fast, the cut is smooth and flat, and generally no subsequent processing is required. The cutting heat affected zone is small, the plate deformation is small, and the slit is narrow (0.1mm ~ 0.3mm); no mechanical stress and no shear burrs; high processing accuracy, good repeatability, and no damage to the surface of the material; NC programming, can process any plan, can cut the entire board with large format, no need Save time by opening the mold.
 
The laser cutting machine can easily process various thickness plates and is very reliable for various thickness plates. Designed for large capacity, it can convert high-speed feed into sheet output. When buying a laser cutting machine, users should pay attention to:
 
1. Buyers must first clarify the production scope, processing materials, and cutting thickness of their own companies, so as to determine the model, format and quantity of equipment to be purchased, and make simple preparations for the later procurement work. The laser cutting machine applications include mobile phones, computers, sheet metal processing, metal processing, electronics, printing, packaging, leather, clothing, industrial fabrics, advertising, technology, furniture, decoration, medical equipment and many other industries. Generally manufacturers will be equipped with many formats for customers to choose from, which can be customized.
 
2. Professionals perform on-site simulation solutions or provide solutions, and can also bring their own materials to the factory for proofing.
 
1) Look at the deformation of the material: the deformation of the material is very small;
2) The cutting surface is smooth: There is little or no burr on the fiber laser cutting machine, the cutting surface is very smooth and the speed is fast.
3) The cutting seam is thin: Generally, the cutting seam of laser cutting is 0.10mm-0.20mm;
4) Power: For example, most factories cut metal plates below 6mm, so there is no need to buy high-power laser cutting machines. 500W fiber laser cutting machines can meet production requirements. If the production volume is large, worry about 500W efficiency Not as good as a high-power laser cutting machine. A better choice is to purchase two or more small-to-medium-power laser cutting machines. This will help manufacturers in controlling costs.
5) The core parts of laser cutting: whether the laser and laser head are imported or domestic. The imported lasers generally use more IPGs, and the domestic ones are usually Ruike. At the same time, other laser cutting accessories are also required. Note that if the motor is an imported servo motor, guide rail, bed, etc., because they affect the cutting accuracy of the machine to a certain extent. A special point to note is the cooling system of the laser cutting machine-the cooling cabinet. Many companies use domestic air conditioners to cool directly. The effect is actually clear to everyone, and it is very bad. To achieve better results.
 
3. Any equipment will be damaged to varying degrees during the use process. In terms of maintenance after the damage, whether the maintenance is timely and the level of charges has become a problem to be considered. Each manufacturer's after-sales service varies widely, and the length of the warranty varies. In the after-sales service, the daily maintenance plan for the customer, for the machine and laser software, there must be a training system to help customers get started as soon as possible.
