Servo-hydraulic press brake PBH(A) series

CNClargeprecision

Product description
Steel plate raw material machined on a large five-axis machining center to ensure structural accuracy and component fit.
Electro-hydraulic servo system with fully closed-loop control for synchronous ram movement.
Dual-rail ram guidance using self-lubricating material for prolonged precision.
Worktable fitted with crowning device and throat-deformation compensation to ensure bending accuracy.
Hydraulic cylinders feature spherical floating supports and specially guided piston rods for strong off-center load resistance.
Backgauge driven by a digital AC servo motor with precision ball screw transmission and linear guide guidance.
