CNC Press Break - PBH

Hydraulic control technology

• The synchronization of press break adopt the technology of full loop electro hydraulic servo control, the positioning signal of the upper beam feedback through optical scale to CNC system, and CNC system will check the opening size of synchronous valves, adjust the inlet oil amount, to relize the synchronizong movement of the upper ram (Y1, Y2) and keep the worktable aways in parallel situation

• According to the technology state of the press break, CNC system can control the amount of crowing compensation of worktable automatically, to achieve consisten angle in whole length

Crowing compensation technology

• Crowing compensation system on the worktable can make the workpiece have same precision full along the length of the worktable; hydraulic crowing compensation system is composed of a group of cylinders in worktable, which can form a relative movements of worktable, forming a curve needed of adding convex to worktable, to ensure the relative position to the upper beam of worktable is unchanged after the worktable being under pressure; the crowing compensation amount if calculated automatically by CNC system according to the thicnkness of the sheet, opening of the tooling and material characteristics.
