Oxy Cutting Service

CNC flame cutting is one of the methods, alongside waterjet cutting, for very thick materials. It is ideal for the conditions where plasma cutting cannot perform any more, which is also its main advantage. It is important to keep in mind, though, that oxy fuel cutting is not suitable for any material.

Oxy Cutting Service

Fractory’s manufacturing partners use CNC machines which have flame cutting torches. Using gas cutting technology we can cut steel plates with a thickness of 10…150 mm. All oxy fuel cutting is in accordance with quality classification EN ISO 9013.

Although it is usually advisable to turn to plasma cutting when facing thick materials, flame cutting services are essential for thicknesses over 50 mm. It is important to note that oxy fuel cutting involves the oxidisation process. Therefore, it limits the possibilities of the method to ferrous metals only.

What is Oxy Acetylene Cutting?

Oxy acetylene cutting is known by many names, such as oxy cutting, oxy fuel cutting or flame cutting. It is a process where fuel gases and pure oxygen are used for cutting.

Oxy cutting cutting uses pre-heating. First, the flame heats up a spot on the metal. Then a high-pressure stream of pure oxygen is directed towards this spot. Hitting the heated spot ignites the oxygen which, in turn, cuts the metal. Flame cutting temperatures rise up to 3500°C.

The cutting head usually has a central hole and some more placed around it. The holes around the central jet are for guiding oxygen and acetylene onto the workpiece to preheat it. The central jet is for oxygen only – it provides the final cutting gas.

Flame cutting is excellent for cutting steel. The reason why it only work well with steel is chemical. When the metal melts, it combines with oxide to form iron oxide. This makes the cut possible.

Therefore, it is a good option when working with ferrous metals but is pretty much unusable with aluminium or even stainless steel. Aluminium oxide has a higher melting temperature than iron oxide. This is why it is not usable there. Stainless steel, on the other hand, is actually used for those non-oxidising qualities, making these metals also unsuitable.

For these reasons, it is necessary to find an alternative when thick plates from other materials than carbon steel need cutting. One possibility is waterjet cutting.

Advantages of Oxy Acetylene Cutting

Cuts thick materials – This is by far the biggest advantage of using a flame cutting service. It enables the cutting of metal up to a thickness of 150 mm.

Portability – It does not require primary power, nor compressed air. Therefore, it is easily portable. The 15 kg set lets you cut metal pretty much anywhere, making it a solution for on-site welding and cutting jobs.

Speed – One of the advantages of an oxy acetylene cutting service is its quickness. It’s especially evident for metals with a thickness over 30 mm. Although plasma cutting is also considered a speedy option, oxy cutting edges it with bigger thicknesses and the gap widens further with the increase of dimensions.

Variety of operations – Oxy fuel torches are not limited to cutting only. Some of the other executable operations include welding of ferrous metals, heat treating, heat shaping, riser cutting and brazing.
