N.KO Bevelling Machines

N.KO Bevelling Machines is a European manufacturer specialising in professional bevelling, edge-preparation and grinding systems for industrial metalworking applications. The company develops machines for precise and repeatable weld preparation on plates, profiles and pipes, serving fabrication companies, steel processors, maintenance teams and heavy-industry production environments.

N.KO Bevelling Machines Company

Founded in 2000 in the Czech Republic, N.KO Machines has developed from a specialised engineering company into an internationally recognised manufacturer of beveling technology. Today, its equipment is used by manufacturers in more than 70 countries worldwide, with applications ranging from general metal fabrication and structural steel to shipbuilding, energy, transport and heavy industry.

The company focuses on the development of machines that replace or reduce manual grinding and uncontrolled thermal edge preparation with controlled, repeatable machining processes. By producing accurate bevel geometry before welding, N.KO systems help improve weld preparation quality, reduce rework and support more consistent production results.

N.KO Machines manufactures its equipment in the Czech Republic and develops solutions for both workshop and on-site use. Its product range includes compact handheld bevelers, automatic-feed plate beveling systems, pipe-end preparation equipment and mobile grinding machines.

Core product categories

N.KO Beveling Machines offers four main product lines:

• Automatic-Feed Bevelling Systems – UZ-Line: automatic-feed machines designed for productive and repeatable bevel preparation on plates, profiles and structural components.
• Manual & Portable Bevelling Systems – B-Line: compact electric and pneumatic systems for flexible edge preparation, deburring, facing, radius machining and weld preparation.
• Pipe Bevelling Systems – Pipe-Line: inside-clamping, outside-clamping and portable machines for pipe-end beveling, facing, J-beveling, counterboring and related preparation operations.
• Mobile Grinding Systems – G-Line: mobile belt-grinding equipment for weld grinding, surface preparation and removal of unwanted layers from large metal surfaces.

Engineering focus

N.KO equipment is engineered around the requirements of weld preparation, edge accuracy and production repeatability. Depending on the selected machine, the systems can perform operations such as V-beveling, double-sided beveling, J-beveling, facing, edge rounding, counterboring, tapering, cladding removal and surface grinding.

The company develops machines for a wide range of materials, including structural steel, stainless steel, aluminium and, with selected models and tooling, higher-strength materials such as HARDOX and DOMEX. Portable and automatic-feed configurations allow equipment to be selected according to workpiece geometry, material thickness, required bevel profile and production volume.

Industrial advantages

Companies using N.KO beveling systems can benefit from:

• Consistent bevel geometry for improved weld preparation.
• Reduced reliance on manual grinding and thermal edge preparation.
• Improved repeatability across long edges and production batches.
• Reduced preparation time and operator effort.
• Flexible solutions for plates, profiles, pipes and fabricated components.
• Portable systems for workshop and on-site applications.
• Automatic-feed equipment for higher productivity and controlled machining.
• A broad range of accessories, cutting tools and configuration options.

Accurate edge preparation is an important part of weld quality. By controlling bevel angle, geometry and surface condition before welding, N.KO machines help create more predictable joint preparation and more efficient downstream fabrication.

Industrial applications

N.KO beveling and grinding systems are used across industries where reliable weld preparation and metal edge machining are required, including steel structures, bridge construction, shipbuilding, oil & gas, rail and heavy industry, wind energy, aerospace and defence applications.

The range is suitable for both workshop production and field work, allowing manufacturers and fabricators to select equipment according to the size of the workpiece, required bevel geometry, access conditions and production demands.

Global presence

N.KO Machines exports its beveling systems to more than 70 countries and supports an international network of partners and distributors. Its combination of European manufacturing, specialised beveling technology and application-focused product development has established the company as a recognised supplier of professional edge-preparation equipment for industrial production.
