Laser cutting machine has been gradually recognized by the majority of users since its appearance. What are the disadvantages of traditional cutting methods and laser cutting machines?
Let’s first look at the difference between laser cutting and wire cutting:
Analysis of advantages of laser cutting machine:
The latest mainstream laser cutting equipment, mainly fiber laser cutting machine and CO2 laser cutting machine.
At present, CO2 laser cutting machine is mainly used for cutting and carving non-metallic materials.
The main advantages of laser cutting are: good cutting quality, high precision, fast speed and low processing cost.
Disadvantages of traditional wire cutting:
Wire cutting equipment can only handle conductive materials, which limits its scope of application and requires cutting coolant during the cutting process. For example, leather is not suitable for wire cutting. If the material is afraid of water and coolant pollution, wire cutting cannot be used.
In addition, according to the type of line used, common wire cutting is divided into fast line and slow line. When wire cutting is made of molybdenum wire, it can be used for repeated cutting. When the wire is cut slowly with ordinary wire, it can only be used once.
PS: Metal wire is used more than molybdenum wire because it is cheap.
Disadvantages of traditional wire cutting: wire cutting can also realize the processing of plates, but the cutting edge will be very rough, and the speed will be slow, which will cause serious environmental pollution.
After discussing the characteristics of laser cutting machine and traditional cutting equipment, the manufacturer will simply compare their cutting principles:
Working principle of the laser cutting machine: high temperature molten materials produced by high energy density laser beam irradiation are purged by high pressure gas. Therefore, the metal materials processed by laser cutting machine should not be too thick, otherwise the thermal shock zone may be too large to cut through.
Optical fiber laser cutting machine is widely used. It can cut most metal materials and is not limited by shape. Its disadvantage is that it can only cut relatively thin sheets.
Traditional wire cutting principle: molybdenum wire or metal wire cutting machine can produce high temperature to cut materials, usually used for mold processing. The more uniform the thermal shock zone is, the smaller it is. It can realize the cutting of thick plates, but the cutting speed is slow, only conductive materials can be cut, and the construction surface is small.
The disadvantage is that there are many consumables, the processing cost is higher than the laser cutting machine, and the environmental pollution is serious.
In a word, both have advantages and can complement each other. However, with the development of industrialization demand, the demand of processing enterprises for large-scale production is getting higher and higher, which means that the production demand of high efficiency, cutting speed, high quality and low cost needs more and more attention. The low cost laser cutting technology is more and more suitable for modern production needs, while wire cutting has gradually lost its market competitiveness.
With the development of technology, the price of laser cutting machine decreases due to the increase in the number of manufacturers. There are many metal plates, and the metal processing industry has chosen to upgrade the laser cutting machine in large part because the traditional cutting equipment can no longer meet the current processing needs.
