The Bielda AC series is the technological pinnacle of BIELDA hydraulic sheet bending presses.

Created by our engineers to be a match for any challenge the Bielda AC series press stands out for its ability to deliver high performance where the production environment demands low volumes and wide product variety.

Carefully selected components, a robust steel frame and a wide variety of standard equipment such as 2 Axis Servo (X, R), bending compensation over long lengths, quick tool change for full length and different setup options make Bielda AC the right choice for complex part production..

When machine setup and set-up times are critical for operators the solution comes from the Bielda AC Series, with the control system featuring an easy-to-use interface that can shorten programming and program load times.

AC series can be configured with 4 axes (Y1, Y2, X and R) up to 12 axes (Y1, Y2, X1, X2, R1, R2, Z1, Z2, AP3, AP4…)
