What is a Gas cutting machine?

A gas cutting machine is a device that uses acetylene gas and oxygen gas to heat and burn steel to cut it. We will explain in detail the operating principle and features of this device.

Principle of gas cutting machine
Gas supply: Acetylene gas and oxygen gas are supplied from the acetylene cylinder and oxygen cylinder, respectively. These two types of gas are released from a vent at the tip of the cutting machine.
Generation of preheating flame: The preheating flame gas is ignited with a special lighter, and by bringing it close to the steel material, the temperature of the steel material is raised. The core of the preheating flame contains a high concentration of oxygen.
Heating and Combustion: The hot steel is further heated by the preheating flame and combusted by supplying oxygen. This combustion turns the steel into a liquid state.
High-pressure oxygen injection: By injecting high-pressure oxygen gas toward the steel, the burning liquid steel is blown into the surrounding area. This will cause the steel to be cut.

Advantages of gas cutting machine
Capable of cutting thick steel plates: Gas cutting machines can generate very high temperatures, so they can cut even thick steel plates.
Highly portable: Suitable for on-site use as only a gas cylinder and a cutting machine are required.
No energy source required: Gas cutting machines do not require an external energy source such as electricity.

Types of gas cutting machines
1. Manual gas cutting machine
Features: Many models are small and easy to move, as they are held and operated by hand.
Advantages: Since it is manual, you can work anywhere, and it is easy to use.
Disadvantages: Since it is operated by hand, accuracy may be difficult to achieve.

2. Automatic gas cutting machine
Features: Specify the cutting position in the program and the machine will automatically cut the steel material. Includes NC gas cutting machines and plasma cutting machines.
Advantages: Can efficiently cut steel materials with high precision and complex shapes, making it suitable for mass production.
Disadvantages: The machine is larger, and the installation space and installation cost may be higher than the manual type.

A gas cutting machine is a device that uses acetylene gas and oxygen gas to heat and burn steel to cut it. Manual types are highly portable and suitable for field work, but accuracy may be difficult to achieve. On the other hand, automatic types are capable of highly accurate and efficient cutting and are suitable for mass production, but they have problems with installation costs and space. It is important to choose the appropriate type according to the purpose and work environment.

Application of Gas cutting machine

The only material that can be cut by gas cutting is basically steel, and grinders and the like are used for cutting medium to thick steel plates, which take a long time to cut. One of the disadvantages of gas cutting machines is that they are not very accurate because they are generally held and used by humans, but large gas cutting machines have dozens of craters and multiple craters at a time. There is also a model that can cut steel sheets with high accuracy.
