Interaxis Distance
The adjustable horizontal spacing between the two lower side rolls of a variable-axis machine, which can be widened to maximize leverage for thick plates.
Technical FAQ
Eliminating material waste and avoiding secondary cutting operations is a primary goal for high-productivity job shops looking to protect their margins. A flat end is the straight, unbent section left at the leading and trailing edges of a plate because the material cannot physically reach the exact tangent contact point between the machine rolls. Minimizing this straight section directly reduces material scrap and eliminates the time-consuming process of pre-bending plates on a separate press brake, thereby accelerating overall floor cycle times. Utilizing Davi all-rolls-drive technology ensures the plate can be positioned precisely at the tangent point to achieve the shortest flat end possible without compromising safety.
Fabricators working on high-precision applications like pressure vessels must ensure perfect roundness from the absolute edge of the plate to comply with strict safety codes. Pre-bending is the preliminary manufacturing step where the leading and trailing edges of a sheet are bent to the target radius before continuous rolling begins. Executing this properly minimizes the flat end, ensures structural integrity at the subsequent weld seam, and reduces the need for manual grinding or expensive re-rolling calibration. Davi 4-roll and variable-axis 3-roll machines are engineered to execute high-tonnage pre-bending safely and accurately in a single automated cycle.
Heavy job shops want to maximize the maximum thickness capacity of their machinery without investing in oversized machine footprints. Interaxis distance is the horizontal spacing between the two lower side rolls of a variable-axis machine. A larger interaxis distance creates a longer leverage arm when the top roll presses down, which drastically reduces the force required and maximizes re-rolling efficiency on thick plate. The Davi MAV intra-frame design allows for an extended side roll stroke, maximizing the available interaxis distance within a compact frame.
