Bielda BC Series Hydraulic Sheet Bending Press, 4–12 Axes

The Bielda BC Series represents the technological pinnacle of BIELDA hydraulic sheet bending presses.

Designed by our engineers to handle any challenge, the Bielda BC press excels in high performance where production environments demand small volumes and a wide variety of products.

Carefully selected components, a robust steel frame, and a wide range of standard equipment such as 2 Servo Axes (X, R), bend compensation for long lengths, full-length quick tool change, and various configuration options make the Bielda BC the ideal choice for complex part production.

When setup and programming times are critical, the Bielda BC Series provides a user-friendly control system that reduces programming and loading time.

• The BC Series can be configured from 4 axes (Y1, Y2, X, and R) up to 12 axes (Y1, Y2, X1, X2, R1, R2, Z1, Z2, AP3, AP4…)
• Standard model with WILA frame deflection compensation
• Standard control with 2D/3D graphics and color display Cybelec 15T, Delem 58T or ESA675 3D CNC
• Automatic unfolded length calculation, programmable bending sequence based on material thickness, type, and available tools. The 2D/3D system automatically optimizes bending sequences considering collision points.
