Explore Kerf’s oxy-fuel cutting machines – designed for reliability, repeatability, and results.
At Kerf Developments, we design and supply robust oxy-fuel cutting machines tailored for heavy-duty metal cutting. From carbon steel and mild steel to thicker plate sections, our systems offer a reliable and proven solution for industries requiring high-quality, cost-effective flame cutting.
With advanced automation, precision motion, and quality cutting torches, Kerf’s machines deliver the accuracy you need – backed by expert support, training, and consumables across the UK and Ireland.
Oxy-fuel cutting (also called oxyfuel cutting, profile cutting or gas cutting) is a thermal cutting method that uses a fuel gas flame – typically oxy-acetylene or propane – to preheat the metal, followed by a jet of pure oxygen that reacts with the heated material.
This reaction generates molten iron oxide, which is blown away by the oxygen stream to create a clean, controlled cut through the steel.
Unlike plasma or laser cutting, oxy-fuel excels at cutting very thick sections of mild and carbon steel using simple, heavy-duty equipment and low operational costs.
✔ Ideal for Thick Materials – Cuts mild steel up to 1,000mm thick

✔ Great for Welding Prep – Clean edges ready for further processing
Whether you're cutting a 20mm plate or a 300mm slab, Kerf’s machines deliver consistent, high-quality results with simple operation and rugged construction.
Built for busy fabrication shops, the RUR series combines oxy-fuel and plasma capability with a robust gantry and automated controls.
✔ Cuts mild steel from 3mm to 150mm
✔ Supports multiple cutting torches
✔ Widely used in engineering and general steelwork
Designed for larger workloads and continuous use, the RUM offers precision cutting of thick plate using up to six torches simultaneously.
✔ Cuts mild and carbon steel up to 300mm
✔ Expandable with wider beds and extra torches
✔ Common in shipbuilding and infrastructure
When only the most powerful machine will do, the MAXI steps up. Engineered for ultra-thick steel and extreme-duty applications.
✔ Ideal for billets, slabs, and heavy stock
✔ Simple to operate with a powerful flame cutting
✔ Customisable in size and torch layout
The flame must be carefully balanced between fuel gas and oxygen, optimised for your specific application and plate thickness.
For the best quality and the most precise cuts on thicker material, OXY-FUEL profile cutting machines are certainly an excellent option to explore. At Kerf, your first choice for CNC cutting machine manufacturing, we can provide a wide range of different OXY-FUEL cutting machine options. Oxy-fuel cutting is a method that has been around for more than a century, dating back to 1907. However, it is still widely used today and is a critical technology in many sectors.
To cut metals, oxy-fuel cutting uses a mix of fuel gases and oxygen. A number of fuels may be used, with propane being the most popular. Speak to Kerf about our profile cutting machines to find out more.
Kerf’s fiber laser systems are engineered for high-speed profiling of mild steel, stainless steel, and aluminium. With their low operating costs, reduced maintenance, and excellent edge quality, they’re ideal for fabricators and manufacturers who need accuracy without compromise.
Whether you're cutting thin sheets or intricate profiles, our fiber laser machines offer unbeatable repeatability and reliability.
Plasma cutters pass an electric arc through gas (often compressed air), which converts into a plasma arc that is used to cut through the metal. The interaction of gases, an electric arc, and a concentrated area of pressure within the cutting torch results in an electrically conductive ionised gas, commonly known as plasma.
Not only can this cutting method get through almost any material you ask it to, it also leaves you with little to no waste, and it is an extremely accurate profile cutting method. When it comes to choosing a cutting system that will offer you everything you need, waterjet cutting ticks all the boxes.
Waterjet cutting employs an abrasive grit carried by an ultra-high-pressure stream of water. This results in a smooth, precision-cut surface without a heat-affected zone.
Waterjet is the most adaptable method since it can cut nearly any material; even carbon steel is no match for it. Waterjet cutting is an extremely accurate process; It features a narrow kerf width, which allows for the cutting of delicate contours and the production of high-tolerance components.
Across the UK, manufacturers trust Kerf’s oxy-fuel cutting machines for their durability, accuracy, and ability to handle thick steel at scale.
At P.P. Group, a custom-built RUM4500 cutting cell with plasma and eight oxy-fuel heads now processes over 400 tonnes of steel per month. Since installing the system, the company has seen 50% faster cutting times, reduced finishing work, and 30% lower consumable use — all while running 24 hours a day, six days a week.
“The Kerf system has been a major contributor to our growth.”
— Peter McCabe, Managing Director, P.P. Group
AJS Profiles also relies on Kerf’s technology, operating 10 machines, including a special MAXI3000G capable of cutting steel up to 1,000mm thick. Their investment has helped cut lead times to just 2–3 days and opened doors to new heavy-duty markets.
“We bought Kerf on a promise of quality, reliability and support – they’ve never let us down.”
— Neil Webb, Director, AJS Profiles
Kerf’s flame cutting machines are built for results – whether you're cutting 20mm plate or tackling ultra-thick profiles.
It’s a thermal cutting system that uses fuel gas and oxygen to burn through steel. The process creates molten iron oxide, which is blown away to leave a clean, defined cut.
Our machines can cut mild and carbon steel up to 1,000mm thick, depending on the model and nozzle configuration.
Oxy-fuel uses a chemical reaction with oxygen to cut thick steel. Plasma uses an ionised gas arc for high-speed cutting of thinner materials. Each method has its advantages depending on the material type and thickness.
Most commonly, acetylene or propane. Acetylene offers a hotter flame, while propane is more cost-effective and favoured for thicker materials.
Yes – provided proper ventilation, PPE, and safety controls are in place. Kerf machines are supplied with suitable safety devices and guidance.
No – it’s only suitable for ferrous metals like mild steel and carbon steel. Non-ferrous metals don’t oxidise in the same way, so oxy-fuel won’t work.
Let’s help you find the right oxy-fuel cutting solution for your operation. Whether you’re looking for faster turnaround, cleaner edges, or better consistency across production, we’ll guide you through the process from first contact to final cut.
