Key Features of the GB Series

Exceptional Precision & Consistency: Utilizes high-end CNC controllers, electronic-scale feedback, and automated deflection compensation to guarantee tight tolerances and minimal scrap.
The system is equipped with automated programming that guides the sheet through complex bending sequences (arcs, hems, closed profiles) without operator intervention.
Powered by advanced motion-control systems and servo drives, the machine’s ram moves rapidly during non-bending phases of the operation. Delivers rapid approach and return speeds for accelerated cycle times.
Intelligent, centralized touchscreen control features automatic pressure calculation and deflection compensation, storing processing parameters for rapid recall.
Integrates premium-grade structural components and servo-driven back gauges to ensure the punch and die meet the sheet metal perfectly every cycle. Maintains exact dimensional accuracy across thousands of bends.

Benefits of Choosing GB Series

Highly Configurable Automation: Easily integrates with premium multi-axis backgauges, advanced angle measuring tools, and robotic bending systems for lights-out, 24/7 manufacturing.
User-Friendly Operation: Equipped with intuitive graphical CNC interfaces that allow even novice operators to rapidly manage programming, thus compressing training times and reducing labor costs.
Eliminates the need for traditional, single-pass V-die methods.. the GB-A series handles special materials, radii, closed bends, and complex hems. Expand your shops capabilities/offerings.

GB Series FAQ's

Q: What materials can the GB Series Press Brake handle?

A: The GB, GB-A, and GB-E Series can process stainless steel, mild steel, carbon steel, aluminum, copper, brass, bronze, galvanized steel, titanium, nickel alloys, steel alloys and so on. Please contact us if you have questions or special applications.

Q: What type of CNC control is used in the GB Series?

A: It uses advanced CNC systems that support multi-axis control, precise programming, and real-time monitoring for complex bending tasks.

Q: What is the bending accuracy of the GB Series?

A: The GB Series achieves high bending accuracy via its rigid build quality, auto-deflection compensation, and linear scales with 0.005mm resolution. This provides repeat positioning accuracy within ± 5 μ m (micrometers), while the overall bending and parallelism accuracy consistently hit ± 0.01 mm.

Q: Is the GB Series suitable for small and large production runs?

A: Absolutely. Its fast setup, tool-changing capabilities, and repeatability make it ideal for both small batch jobs and large-scale production. Also, please see the GB-A series, automated version of the GB hydraulic presses.
