Bielda BC C270-4100 Press Brake

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

Designed by our engineers to meet any challenge, the Bielda BC series stands out for delivering high performance where production environments require 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), long-length bending compensation, quick full-length tool changes, and different configuration options make the Bielda BC the ideal choice for producing complex parts.

When machine setup and configuration times are critical for operators, the Bielda BC series provides a solution with a user-friendly control system that can shorten programming and loading times.

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