Metal and sheet metal oxyfuel cutting is a particular type of metal working that consists of a cut that takes place thanks to the action of an acetylene flame and oxygen.

Metal and sheet oxyfuel cutting: the principles of chemistry for a precise and effortless cut


Oxyfuel cutting processes are known for their very high precision, their simplicity and the fact that there are almost no limits to the thickness to be cut. Oxyacetylene cutting is in fact one of the most used and tested cutting methods for carbon alloys. Today it is possible to cut ingots up to 1200mm high with a precision of a few millimeters. The new technologies used allow us not only to perform vertical cuts but also three-dimensional cuts on all sides of the piece, with chamfers, countersinks and anything else that can avoid subsequent and expensive machining.

How it works

Those rich in carbon, in fact, develop a particular reaction when they come into contact with oxygen. For this reason the cutting of metal sheets or profiles by oxyfuel cutting is mainly applicable with mild steels, i.e. those rich in carbon. The procedure is not recommended and optimal, for example, for stainless steels, for which other types of cutting and machining such as plasma cutting are applicable.

How metal and sheet metal oxyfuel cutting works

Oxyfuel cutting is the process of cutting metal sheets and profiles using the thermal energy produced by a flame formed by combustion between LPG (combustible gas) and Oxygen (combustion gas), thanks to a chemical reaction of oxidation at high temperature, between the Oxygen itself and the metal to be cut.

The chemical principle of cutting is a process of oxidation of the carbon contained in the ferrous material in the area of combustion gas passage.

This oxygen wire, which is created at the exit of the central area of the cutting tip, allows the removal of exactly 3mm to 7mm of material over the entire height of the sheet metal thickness. The movement at controlled speed on a predetermined path and managed to the tenth by a numerical control, allows us to obtain a work of the highest precision and quality.

The possibility in recent years to tilt the torch and rotate it at will around an axis also allows us to create chamfers and countersinks of large dimensions.

This is exactly what happens at Tecnos’ headquarters in Cuggiono, where every day we produce sheet metal for every industrial need, especially for sectors such as oil, energy and chemicals.

We also operate on large dimensions

Thanks to Tecnos metal and sheet metal oxyfuel cutting, it is possible to obtain metal elements of all sizes, destined to be used in every industrial sector, from the retail sector to large works.

In our location, in fact, we have six sheet metal cutting machines with four 3300mm x 28000mm operating planes with 5 automatic packing torches, equipped with a drilling machine to be used when needed, indispensable to solve the problems of breaking through thicker thicknesses with small holes.

In addition to sheet metal oxyfuel cutting, we also carry out other processes such as sheet metal crimping and other metal carpentry processes.
