Accurate Bending Starts with Perfect Compensation

In press brake operations, deflection in the upper beam (ram) and lower table under load is inevitable. This deflection often leads to inconsistent bend angles, concave deformation in the center of long workpieces, and increased scrap rates. Many operators mistake this for springback issues, but the root cause is usually inadequate crowning.

Our Crowning Table solves this problem by automatically compensating for machine deflection, ensuring uniform bending angles and high repeatability across the entire length — even when material tensile strength or bending pressure varies.

Why Choose AccurTool Crowning System?

How the Crowning System Works

A hand crank or CNC-controlled motor drives the upper wedge blocks to shift lengthwise relative to the fixed lower wedges. This movement creates a precise counter-curve that exactly matches and offsets the natural deflection of the press brake under load.

The system can be installed either on the upper beam or directly on the worktable. By pre-setting an opposite deformation, it ensures the die remains straight during bending, eliminating center concavity and delivering consistent angles from end to end.
