プレスブレーキは、長尺板の曲げ精度の不均一さをどのように解決しますか？

How Does Press Brake Solve the Uneven Bending Accuracy for Long Plates? Introduction: Achieving Uniform Bending Accuracy on Extended Workpieces Press brakes address uneven bending accuracy for long plates—also known as long workpiece deflection or extended sheet angle inconsistency—through advanced crowning systems, precise CNC compensation, and optimized tooling. These technologies counteract ram-to-table deflection and material springback, ensuring consistent bend angles across workpieces over 3 meters. This eliminates the dog-leg bending distortion, where the center bends sharper than the edges. Deflection Impact: For plates exceeding 3 meters, high loads cause angle variations up to 2°. Crowning Solution: Hydraulic or CNC-controlled systems restore parallelism, achieving ±0.2° repeatability per DIN 8605 standards and […]
