What are the classification features of flame cutting machine?

Flame cutting machine, is the use of gas with oxygen or gasoline with oxygen metal material cutting equipment. Mainly used in heavy industry.

Classification of flame cutting machine:

It is mainly divided into early manual cutting (commonly known as oxygen welding) and semi-automatic cutting machine, copying cutting machine and CNC cutting machine, with the progress of society and the development of science and technology, more and more advanced, cutting function is more and more powerful.

The main structure of the model is: manual; Copying cutting machine, portable CNC cutting machine, cantilever CNC cutting machine, gantry CNC cutting machine, desktop CNC cutting machine and specially used for pipe intersecting line intersecting line CNC cutting machine, the above structure can use flame cutting method for cutting.

According to the metal material and the thickness of the cutting metal from the point of view of the process, generally more than 5mm carbon steel plate is recommended to cut with flame, because the thermal deformation of such steel plate is very small. Stainless steel and non-ferrous metals can not be cut with flame, the reason is that stainless steel in the surface after heating high density oxide layer, prevent heat transfer down, thus affecting the plate fusing; Non-ferrous metals such as copper and aluminum have strong heat dissipation capacity, resulting in the rapid loss of heat in the cutting surface, and also affect the plate fusing.

Features of flame cutting machine:

Compared with plasma cutting: the temperature of flame cutting is lower than that of plasma cutting, which directly leads to its cutting rate less than plasma, and can not cut stainless steel and many non-ferrous metals. Its advantage is that it can cut large thickness plate (China has mastered the flame cutting technology cutting 2000mm thickness), cutting equipment and cutting cost is relatively low, less pollution than plasma cutting machine.

Compared with laser cutting: flame cutting machine in cutting speed accuracy and cutting material types are far less than laser cutting machine, but in cutting thickness and cutting cost are superior to laser cutting machine.

Compared with high pressure water jet cutting machine: high pressure water jet cutting machine precision and cutting material types are better than flame cutting machine, but flame cutting machine in cutting speed and cutting thickness are greater than water cutting machine, and equipment cost and cutting cost are relatively low.

After comprehensive comparison, the conclusion is that the flame cutting machine has small production input and large processing thickness, which is suitable for rough processing industry with low precision requirement.
