Professional Weld Preparation for Railcars, Locomotives & Heavy Equipment
High-performance beveling solutions for vehicle manufacturing heavy machinery, construction equipment and welded structural components.
Railcars, locomotives and heavy equipment operate under constant vibration, cyclic loading and demanding working conditions.
N.KO beveling machines deliver accurate, repeatable weld preparation across production runs - helping manufacturers improve consistency, increase productivity and reduce manual grinding and rework.
Consistent weld preparation for demanding North American rail manufacturing requirements, including applications performed to AWS D15.1.
Structural components are designed for:

Accurate, repeatable bevel geometry provides a consistent foundation for high-quality welds in dynamically loaded structures.


Machine-controlled beveling delivers repeatable edge preparation across production batches an multiple operators.
Prep time drops sharply versus hand grinding, lifting throughput and efficiency on serial runs.


High-strength steels up to 100 ksi (690 MPa) and beyond; machining keeps their properties intact by avoiding heat.
A controlled prep process cuts the odds of defects that show up as warranty claims or long-term trouble.

They all share the same challenge: ensuring long-term reliability under dynamic load conditions.
In transport manufacturing, quality issues often appear after years of use — when repair is most costly.
Beveling machines help ensure that welds are prepared correctly from the beginning, improving durability and reducing long-term risk.
At the same time, they contribute to faster production and more consistent results across batches.
