Bielda BC220-3100 Press Brake

The Bielda BC series represents the technological pinnacle of BIELDA hydraulic press brakes.

Designed by our engineers to meet any challenge, the Bielda BC series stands out for its ability to deliver 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), long-length bending compensation, full-length quick tool change, and different configuration options make the Bielda BC the ideal choice for producing complex parts.

When setup and machine configuration times are critical for operators, the Bielda BC Series offers a control system with an easy-to-use interface that can shorten programming and loading times.

• 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…)
• The standard model features a WILA frame deflection compensation system
• Standard control system with 2D/3D graphics and color screen: Cybelec 15T, Delem 58T, or ESA675 3D CNC
