Explore Kerf’s CNC plasma cutting machines engineered for maximum precision and performance.
At Kerf Developments, we engineer and supply industry-leading plasma cutting machines that deliver high-performance results across a wide range of metal cutting applications. Whether you're working with mild steel, stainless steel, or thick steel plate, our CNC plasma cutting machines are designed to handle both light and heavy workloads with exceptional cutting speed, precision, and repeatability.
We offer a complete solution — from machine and control systems to consumables, spare parts and support — so your team can focus on production, not troubleshooting. Whether you're upgrading from a basic system or investing in your first CNC plasma cutter, Kerf provides trusted expertise and proven results.
Plasma cutting is a highly efficient metal cutting process that uses a plasma arc to slice through electrically conductive materials. The method sends a high-voltage electrical arc through a gas to generate hot plasma, melting the metal almost instantly. The molten material is then blown away by the gas stream, leaving a clean, precise edge.
When integrated with CNC controls, the plasma cutting process becomes highly automated and accurate — ideal for fabrication shops, production lines, and CNC applications where parts need to be nested efficiently.
At Kerf, we’ve spent decades refining our machines and partnerships to deliver maximum value to our customers. Here's what sets us apart:

With Lincoln Electric’s high definition plasma systems and UltraSharp enhancement, you can expect:
Correct machine setup, clean air supply, and trained operators are key to maximising performance. We’ll support you with all of the above.
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.
Clonakilty Engineering in Ireland transformed its production by bringing profiling in-house with a Kerf RUR2000p high-definition plasma cutting machine. By replacing outsourced laser cutting with their own CNC plasma system, they cut lead times from days to hours, reduced costs, and improved flexibility.
Since the switch, they've handled over 50,000 piercings, recovered €1,000/month in scrap steel, and increased annual growth by 30%. The addition of UltraSharp technology and the Burny 10 LCD controller has helped them nest parts more efficiently and maximise every sheet.
“I thought we needed a laser. Kerf showed us otherwise. It’s changed how we run the business.”

Kerf’s CNC plasma cutting machines operate on either single-phase or three-phase power, depending on the model. We’ll help match the current to your mains supply for optimal performance.
A pilot arc allows the plasma cutter to initiate the cut without touching the material, making it ideal for rusty, painted, or uneven surfaces. It also helps extend the life of the cutting tip and torch body.
Maintaining the correct air pressure is crucial for achieving a clean cut and prolonging the life of your plasma cutting torch components. We recommend using a reliable air pressure regulator and a suitable air compressor for consistent performance.
Yes — all our plasma cutters are engineered to handle both thin and thick materials, from aluminium and stainless steel through to heavy carbon steel and wear-resistant plate.
Our plasma cutting equipment is designed with safety in mind. High-performance systems generate a high voltage plasma arc; therefore, personal protective equipment (PPE) and training are essential — all covered during installation.
Not at all. Our machines are built for industrial environments and feature premium components. Routine checks and proper air quality help keep everything running smoothly.
Thanks to UltraSharp technology, our high-definition plasma cutters produce bolt-ready holes, minimal bevel, and excellent edge quality — often comparable to laser performance.
Let’s help you find the right plasma 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.
