Comparison of traditional and laser cutting – Damon

Comparison of traditional and laser cutting – With the rapid development of the metal processing industry today, due to production needs, the demands for cutting metal materials of different materials, thicknesses, and shapes have greatly increased. It poses a severe challenge to metal cutting technology. The competition in the metal processing industry has become more and more fierce.

First of all, let’s learn about the advantages and disadvantages of traditional processing industry technology. Comparison of traditional and laser cutting. The traditional cutting method mainly includes CNC shearing machines, punching machines, flame-cutting, plasma cutting, and high-pressure water cutting.

Shearing machine

A shearing machine, also known as a steel plate shearer. It is a machine that uses one blade to reciprocate linear motion relative to the other blade to cut the plate. It belongs to one kind of forging machinery and mainly applies to metal plate processing. So it only needs straight cutting. This kind of equipment has low cost and simple operation. The purpose relatively single, not flexible. And it doesn’t support cutting a variety of graphics pattern.

Punching machine

The punch is a punching press. It is mainly suitable for cutting simple graphics such as square holes and round holes. So it improves the flexibility in curve processing. Some specific metal sheet workpieces can process at one time. And the processing speed of thin plates is fast. Disadvantages: First, the ability to stamp thick metal plates is limited, and the main processing objects are carbon steel plates with a size of less than 2mm. Second, the punching process will depend on molds. And mold development circle are long, production costs increased. And the degree of flexibility is not high. The third is that the processing surface of the thick steel plate is not smooth. So it is easy to produce collapse grooves, and the conventional forming will cause certain damage to the outer surface of the material. And processing noise is loud.

Flame cutting

Flame cutting is the initial thermal cutting method, namely gas cutting. Traditional flame cutting has experienced acetylene gas cutting, propane cutting. Now the widely used natural gas cutting. The cost of flame cutting equipment is low. It supports the cutting of thick steel plates, and the market has a very large stock. Its disadvantages are that the cutting thermal deformation is too large, the slit is too wide. And the utilization rate of the plate is low. It is only suitable for rough processing products and requires secondary processing.


Plasma cutting

Plasma cutting is a processing method that uses the heat of a high-temperature plasma arc to melt and evaporate the metal part or part of the incision of the workpiece and uses the momentum of the high-speed plasma to remove the molten metal to form an incision. The advantage is that the cutting speed is fast, the cutting surface is smooth, and it supports various metals that are difficult to cut by oxygen, especially for non-ferrous metals. The disadvantage is that the cutting seam is wider, the cutting surface is not smooth, and it is easy to produce a large amount of metal dust, glare, etc problem. Production safety cannot be effectively guaranteed.
