LVD compound die radius allows material to flow more evenly
The name of LVD's patented compound die radius, 'STONE' press brake tooling, is extracted from the sales message: Shaped Tooling for Optimal beNding without wEar. It 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 design of the V-die reduces the friction encountered between the material and the die when bending by creating a rolling condition as the material enters the die. The radius assures accurate bend angles along the entire bending length.
LVD also says that Stone tooling reduces marks, nicks and carbon deposits that can occur on the workpiece as the material rolls through the die. Other benefits cited include reduced tool wear, tool interchangeability, reduced residue on stainless steel, improved material control, reduced tonnage requirements and symmetric bending.
