With the increasing advancement of laser technology, more and more metal processing companies choose fiber laser cutting machines for processing and production. However, due to the high price of fiber laser cutting machines, many customers do not have enough budget to purchase high-power fiber laser cutting machines. Therefore, how to buy the most suitable fiber laser cutting machine within a limited budget becomes particularly important. There are several factors to consider:
Fibear Laser Cutting Machine accuracy is the basis for selecting a machine tool, which refers to the contour accuracy of the cutting work piece, rather than the static accuracy marked on the sample.
The difference between a good machine and a poor machine is whether the accuracy of the high-speed cutting of the part will change, and whether the consistency of the workpiece will change greatly when cutting at different positions!
Fiber Laser Cutting Machine efficiency is an indicator of the profitability of a laser cutting machine. Cutting efficiency refers to the cutting time, rather than simply looking at the cutting speed! The parameters can be faked, only the cutting time cannot be faked!
The higher the cutting efficiency, the higher the processing cost and the lower the running cost. It is a tool to earn money!
At present, the main maintenance cost of the laser cutting machine is in laser maintenance!
However, the maintenance cost of each laser is different.
4 , The Service Life:
The service life is an evaluation of the machine to save money, the longer the service life of the machine, the lower the depreciation expense of the laser cutting machine.
The main factors that determine the life of a machine tool are as follows:
The rigidity of the machine tool, simply speaking, the heavier the tonnage of the machine tool, the better the rigidity!
The configuration of the machine tool, as well as the brand and quality of the transmission device!
Process manufacturing level, enterprise process accumulation and inheritance of experience!
Second, Common Problems
1.Dynamic characteristics and acceleration of the equipment
The quality of the dynamic characteristics is simply the contour accuracy of the high-speed cutting parts. In theory, the greater the acceleration of the machine tool, the better the dynamic characteristics of the machine!
The standard method for the calibration of acceleration is to use the uniaxial acceleration notation. For example, the uniaxial acceleration of the German Express is: 1.5g . At present, many companies on the market use composite acceleration labels such as: 2-3g , which is easy to build.
The way to identify the authenticity of the acceleration is to cut a more complex part at high speed and see the cutting time; you will find that 1.5g is faster than some 3g acceleration!
2.welding steel beam and cast aluminum beam (aluminum cold drawn beam) Which is better?
The machine tool needs to obtain good dynamic characteristics, and the lighter the beam rigidity is, the better!
At present, the beams used by mainstream brands are usually cast aluminum beams or aluminum alloy cold drawn beams. The cast aluminum beams have good shock absorption performance, so they are used more.
Welded steel beams can only be welded with very thin steel plates ( about 3 mm). If the weight is too heavy, there will be no good properties. However, the thin steel plate cannot be annealed during welding, so the beam will be deformed after a period of use. It is recommended to examine the accuracy of this type of equipment using a high-speed cutting plate for a period of time.
3.What is the significance of the machine tool tonnage and the maximum speed of the machine tool?
In theory, the heavier the tonnage of the machine tool, the better the rigidity of the machine tool. The longer the life of the laser cutting machine, the faster the running speed can be carried!
