LVD Company nv offers precision ground tooling with its patented STONE® radius for all models of LVD press brakes.
A special patented compound die radius, STONE tooling (“Shaped Tooling for Optimal beNding without wEar”) is produced with a progressive radius on both sides of the V-opening, allowing the material to flow into the die more evenly and with less drag. The unique design of the V-die reduces the friction between the material and the die encountered when bending by creating a rolling condition as the material enters the die. The STONE radius assures accurate bend angles along the entire bending length.
STONE tooling also diminishes marks, nicks and carbon deposits that can occur on the workpiece as the material rolls through the die.
Benefits include reduced tool wear, tool interchangeability, reduced residue on stainless steel, improved material control, reduced tonnage requirements and symmetric bending.
