CNC oxy fuel cutting is done on almost all metals, including mild steel, stainless steel, aluminum, cast iron, etc. The cutting system functions by utilizing the oxy-fuel cutting torch, which generates heat to melt the metal. The molten metal is thus eliminated by a direct stream of oxygen to the molten area.
There are a variety of CNC oxy-fuel cutting torches available on the market. They are differentiated by their functioning and the type of metals they cut.
These are the most commonly used types in CNC cutting systems. They have been preferred for their simplicity in operation and flexibility. They are mostly applied in cutting mild steel because they effectively manage to reach the required temperature for cutting.
These are automatic torches used in CNC cutting machines. They have been programmed to ensure precision in cutting. They are excellent tools in the mass production industry, where uniformity in cutting is required.
These types of torches are employed in CNC cutting of thick metal plates. They have robust designs, which enable them to achieve higher temperatures, therefore suitable for more massive cutting work.
These cutting heads are attached to CNC cutting machines. They are useful when replacing worn-out cutting nozzles or replacing them with new ones. Cutting heads also operate well with CNC machines that primarily utilize oxy-acetylene cutting.
Automated Oxy-acetylene torches are mainly applied in large production facilities. They are synchronized with robotic systems. These auto-cutting torches are perfect for extensive and precise mass cutting operations.
Metals to be cut by CNC oxy fuel cutting need higher temperatures to be attained. They work by principle differences in melting temperatures. The materials used to manufacture CNC oxy acetylene cutting torches include brass, copper, stainless steel, and aluminum alloys.
Brass is usually used due to its high durability and resistance to wear and corrosion. Brass also contacts the internal components of the torch while ensuring efficient heat conductivity.
Copper is mostly preferred in constructing the electrodes and other parts of the torch, considering that it has high electrical conductivity. It is also used to manufacture someOxy-acetylene welding and cutting kitsthat have heat resistance properties.
Stainless steel is mostly used due to its corrosion and oxidation properties. Stainless steel is also used in constructing a CNC oxy acetylene torch in areas of high stress and temperatures.
Aluminum alloys are preferred to the copper brass variety for their lightweight properties. They are mainly used in non-industrial CNC cutting torches. They have excellent resistance to corrosion, which makes them useful tools in workshops.
Oxygen cutting machines can cut a wide range of metals, from thin sheets to thick plates. The key factors influencing the cutting process are the type and thickness of the material.
Mild steel is the easiest and most economical metal to cut. Mild steel has an ideal thickness value of approximately 1-30 mm. For the efficient and economic CNC oxy acetylene cutting torch, mild steel is the most common material used.
Stainless steel is cutting-resistant and is cut using CNC oxy acetylene cutting torches, although it requires higher cutting temperatures. Stainless steel is mainly useful when cutting materials that need to resist rust and corrosion.
Various CNC oxy-acetylene cutting machines cut aluminum alloys; thus, aluminum is one of the metals. Aluminum requires a cutting torch that can maintain a steady flame while control of the heat is ensured.
CNC oxy acetylene cutting torches cut cast iron. Cast iron uses a slower cutting speed to achieve better results. Great care should be taken when cutting cast iron, as the material may crack due to adverse heat effects.
CNC oxy acetylene cutting torches are commercially used in various industries depending on the cutting precision, speed, and efficiency required on the materials. The following list explains the most common commercial applications of these torches.
In this industry, CNC oxy acetylene cutting machines cut metal components like brackets, frames, and supports. These parts are used in constructing machinery, vehicles, and buildings. The precision cuts ensure that fabricated parts fit perfectly during assembly.
These torches in the aerospace industry cut lightweight alloys and other hard metals used in aircraft construction. CNC cutting provides an accurate cut to complicated aerodynamic shapes required for wings, fuselages, and engine components.
In the shipbuilding industry, large metal plates are cut to form the hulls of ships and other vessels. The CNC oxy acetylene cutting is suitable for handling these thick materials to ensure precise cuts that maintain the structural integrity of the vessels.
In the automotive business, these cutting machines cut car frames, engine blocks, and other major components. Oxy acetylene cutting provides strong welds, which are essential for maintaining increased safety standards in car production.
These cutting torches are used in the building industry to cut steel beams, reinforcement bars, and various metal sections used in structures. CNC cutting ensures the accuracy of the cuts to the desired lengths and angles for the safe and speedy installation in various construction projects.
The following factors should be considered when choosing the best CNC oxy acetylene cutting torch.
The required cutting torch highly depends on the thickness of the metal to be cut. A simple-hitting torch will do for thin metals, while heavy-duty ones will be required for thick plates.
To ensure compatibility, the torch's cutting head should match the CNC system. Each CNC system has its unique requirements regarding the torch's mounting, operating interfaces, and control mechanisms.
The cutting speed and quality achievable are directly influenced by the torch size and design. A larger mixing chamber of a torch will increase the cutting speed because more gas mixes will flow through it.
The efficiency of fuel is an important cost factor to consider. Oxy-acetylene cutting torch tends to consume more fuel, which may be expensive, especially if used for extensive cutting work. On the other hand, the CNC propane-oxy cutting torch is more fuel-efficient and economical.
Considering these factors will enable one to choose an efficient CNC oxy acetylene cutting torch that will meet all the cutting requirements economically and efficiently.
A1: The most cutting fuel in CNC oxyacetylene cutting machines is an oxygen-acetylene mixture. It generates flame temperatures of approximately 3,200°C. This temperature is high enough to melt and cut through any metal.
A2: CNC oxy acetylene cutting machines are widely used due to their ability to cut moderately thick metals with great accuracy and speed. Oxy acetylene cuts are also economic when cutting large metal sheets or heavy plates, as they require lower operational costs than electric plasma cutters.
A3: Yes, Cnc oxy acetylene cutting torches can cut stainless steel. Acetylene mixed with oxygen has high flame temperatures, which can cut stainless steel. Proper settings and technique must be applied to ensure clean and precise cuts without warping the material.
A4: Oxy-fuel cutting torches are used to cut ferrous metals like mild steel, stainless steel, cast iron, and other metals. Non-ferrous metals such as copper and aluminum are also cut using specialized techniques and torches.
