Comparison of flame, plasma, laser metal cutting machines in the market

In the metal cutting market, the main metal cutting machines are CNC flame cutting machine, CNC plasma cutting machine and CNC fiber laser cutting machine. We will introduce the characteristics of these metal cutting equipment.

1. cutting mode:

CNC flame cutting machine, cutting thick carbon steel cutting ability, cutting cost is low, but there are large cutting deformation, cutting accuracy is not high, and cutting speed is low, cutting preheating time, long piercing time, it is difficult to adapt to the needs of automatic operation. Its application is mainly limited to carbon steel, large thickness plate cutting, in the medium and thin carbon steel plate cutting will be gradually replaced by plasma cutting.

CNC plasma cutting machine, plasma cutting with a wide range of cutting fields, cutting all metal sheets, cutting speed, high efficiency, cutting speed up to 10 m / min or more. Plasma cutting under water can eliminate noise, dust, harmful gases and arc pollution, and effectively improve the working environment. The use of fine plasma cutting has made cutting quality close to laser cutting level. With the maturity of high-power plasma cutting technology, cutting thickness has exceeded 150 mm, expanding the CNC plasma cutting machine cutting range.

CNC optical fiber laser cutting machine has the characteristics of fast cutting speed and high precision. Laser cutting machine is expensive and high cutting cost. It is only suitable for thin plate cutting occasions with high precision requirements.

2. mechanical structure:

Gantry type numerical control plasma cutting machine is the vertical structure of double-base beam pedestal of traditional large and medium-sized machine tools. It has large span and longitudinal walking distance and is suitable for large plate processing. Cantilever CNC cutting machine is also a traditional classical mechanical structure, a single base and one end of the beam, cutting gun on the beam transverse movement, such equipment suitable for small and medium plate processing

Portable plasma flame cutting machine is developed from semi-automatic car-type cutting machine. It is equipped with numerical control system and transmission device. Its basic shape is similar to that of car-type semi-automatic cutting machine. This kind of machine has low cost, light structure and is especially suitable for small and medium-sized plate processing.

Desktop cutting machine is developed from engraving machine. It is similar to adding a miniature gantry cutting machine on the worktable. This kind of equipment has great advantages in the field of sheet metal cutting, and is widely used in advertising and automobile sheet metal industry.

CNC intersecting wire cutting machine belongs to special cutting machine, its structure is special, special for cutting pipe and cylindrical profiles, at present domestic manufacturers are not many, demand is not large.

Robot cutting machine is a new type of cutting machine developed abroad. Its cutting gun is mounted on a manipulator arm. It has a numerical control system to realize multi-axis linkage. It can process three-dimensional special-shaped workpiece and realize 3D cutting. This kind of equipment is complex in technology and high in cost. Domestic equipment mainly comes from imports.
