Discover ABM-R5 Auto-Feed Radius Beveller
ABM-R5 is designed to round the top and bottom edges of steel plates and profiles with radius of R2, R3, R4, or R5. By producing a repeatable, uniform radius the machine makes parts safer to handle, and helps prepare plates and profiles for downstream welding, coating, and assembly.
The PROMOTECH ABM-R5 Auto-Feed Radius Bevelling Machine is a new addition to our portfolio of steel plate and profile edge preparation solutions. ABM‑R5 is a practical solution for repeatable radius milling and bevelling of long I‑shaped structural steel beams, including standard I‑beams, wide‑flange, and narrow‑flange profiles.
In practice, this means the PROMOTECH ABM-R5 helps deliver cleaner edge quality, better process consistency, and improved readiness for further production steps. Moreover, ABM-R5 also enables straight bevels with a maximum width of 6 mm at 45 degrees on the upper and bottom edges and 6 mm at 30 degrees on the upper edge of the workpiece.
The milling head position can be easily adjusted with an accuracy of 0.1 mm, enabling operators to set the required geometry quickly and precisely.
Thanks to its self-propelled auto-feed system and 4-wheel drive with magnetic traction, the ABM-R5 Auto-feed radius beveller moves directly along the workpiece and does not require a guide track. It produces high-quality results without thermal distortion and without creating a heat-affected zone (HAZ), which is especially important in demanding fabrication environments where edge quality directly affects downstream welding and finishing operations.
Let’s now explore the ABM-R5’s application capabilities in more detail. Optional milling heads allow users to configure the machine to match specific application and production requirements.
ABM-R5 application – The upper edge
Radius R2, R3, R4, or R5 mm
Minimum workpiece thickness: 8 mm
Minimum width: 150 mm (e.g. I-beam flanges)
45 degrees bevel up to 6 mm wide
Minimum workpiece thickness:8 mm
Minimum width: 30mm
30 degrees bevel up to 6 mm wide (option)
Minimum workpiece thickness: 8 mm
Minimum width: 30mm
ABM-R5 application – The bottom edge
Radius R2, R3, R4, or R5 mm
Maximum workpiece thickness: 30 mm
Minimum width: 150 mm
45 degrees bottom-edge bevel (option)
Bottom-edge bevels up to 6 mm wide
The maximum workpiece thickness: 30 mm
Stable auto-feed travel with smart overload control
The ABM-R5 moves from left to right along the workpiece at a stable speed of up to 2.0 m/min. Milling starts 200 mm from the left edge of the workpiece and ends 20 mm before the end of the plate. At the end of the operation, the machine automatically stops and retracts, keeping the milling head away from the material.
This “automatic stop and retraction” function helps reduce unnecessary tool wear, minimizes the risk of accidental damage to the workpiece, and prevents unwanted contact once machining is complete.
The remaining sections — 200 mm at the beginning and 20 mm at the end — can be machined using the PROMOTECH BM-6 Battery beveller, making the two machines a practical combination.

Built for safe, reliable, and user-friendly operation
The ABM-R5 is equipped with features that enhance both operator safety and everyday usability. Its robust yet compact design allows for easy positioning and convenient handling in a wide range of working environments.
To ensure stable operation and protect the machine during demanding applications, the ABM-R5 features a feedback-controlled smart overload system. This system continuously monitors the load and automatically reduces the travel speed when necessary, for example when the cutting inserts become worn or when machining harder materials.
Together, these features help reduce operator effort while supporting consistent and repeatable quality.
Reliable preparation for subsequent fabrication processes
Thanks to its trackless operation, magnetic traction, precise adjustment, and versatile machining capabilities, the ABM-R5 enables reliable weld preparation and improved productivity. The rounded edges it produces ensure better coating coverage and paint adhesion, which is essential for effective corrosion protection.
By machining both the upper and bottom edges, the PROMOTECH ABM-R5 enhances the quality of subsequent fabrication processes while combining compact dimensions with solid performance.
