GB-E Series

The Glorystar GB-E Series All-Electric Servo Bending Machines combine high-speed servo-driven performance, exceptional bending accuracy, and energy-efficient operation in a compact, modern machine design. Unlike traditional hydraulic press brakes, the GB-E Series uses a fully electric servo-driven architecture that eliminates hydraulic oil while delivering faster cycle times, reduced maintenance requirements, and consistent bending performance. Designed for manufacturers requiring precision, repeatability, and lower operating costs, the GB-E Series is ideal for sheet metal fabrication, electrical enclosures, appliance manufacturing, HVAC components, and other precision bending applications.

About GB-E Series

The GB-E Series is Glorystar’s all-electric servo bending platform, engineered to provide high-speed bending performance with exceptional accuracy and efficiency. Using precision ball screws, servo motors, electronic feedback systems, a four-axis backgauge, and Glorystar’s proprietary SL100-P CNC control, the GB-E Series delivers precise ram positioning and repeatable bending results without the complexity of a hydraulic system.

By eliminating hydraulic oil, pumps, valves, and associated maintenance requirements, the GB-E Series helps manufacturers reduce operating costs while improving workplace cleanliness and energy efficiency. Depending on the application, energy consumption can be reduced by up to 80% compared to conventional hydraulic press brakes.
