High Radius Steel Plates

Creating a radius up to 2mm is often requested in steel plates as a preparation for powder coating or galvanizing. Achieving this R=2mm brings a much higher cost both in terms of abrasive consumables and in terms of processing time, so it needs to be clear this is really a necessary requirement. 

Several steel construction companies working on steel plates cutting for offshore, machine building, cranes construction and other steel fabrication require the deburring and edge rounding of these thick plates after oxy-cut or plasma cut. 

NS Máquinas achieves this result in 2 steps with the steel plated deburring and edge rounding machines DM1100 DC and DM1100 DCC or variations of these models which makes the steel metal sheets deburring and edge rounding faster.


Oxy Cut steel plate before deburring


1st: DM1100 DC contact drum eliminates heavier burrs by concentrating the pressure on the edges of the steel plates (oxy cut or plasma cut).

2nd: Once deburred, with a sequence of edge rounding abrasive brushes DM1100 DC creates a big radius on steel parts. 

See the results below:

DM1100 DCC 2.5mm radius 


The deburring and edge rounding process is relatively slow (conveyor belt speed under 0.5m/min), but the rounding is extreme and consistent. 


Measuring radius on steel oxy cut part


DM1100 DCC deburrs, deslags and edge round thick steel plates oxy cut or plasma cut. Its deburring solution and concept is quite unique and specially dedicated for thick steel plates deburring and edge rounding. The large diameter deburring drum D (Ø435mm) with extra soft rubber concentrates the pressure on the edges where the burr is located, leaving the surface of the material lightly touched only. Deburring contact drum floats every time there is extra pressure or to cope with small tolerances on the metal. This is particularly important in thick steel plates,

Edge rounding result is achieved by a sequence of abrasive tools assembled on a cross belt system. The pressure made by the deburring and edge rounding blocks, guided by a system where the pressure is controlled is key to achieve high edge rounding results. With different speeds we can obtain roundings from 1.8 to 2.3mm.
