Product Overview
Introducing the GB-3512E All-Electric Servo CNC Press Brake from GloryStar, offered exclusively through Omni Machine Inc. — a precision bending solution built for shops that demand accuracy, speed, and zero hydraulic maintenance. Unlike conventional hydraulic press brakes, the GB-3512E uses high-performance servo motors to drive the ram, delivering cleaner operation, faster cycle times, and repeatable accuracy bend after bend. With 39 tons of bending force and a 4-foot bending length, this machine is purpose-built for job shops, fabrication houses, prototyping operations, and production environments working with light to medium gauge sheet metal.
GloryStar's GB-E Series all-electric servo press brakes eliminate the hydraulic system entirely — no oil, no pumps, no seals to replace, no temperature-related drift. The result is a machine that runs quieter, uses less energy, and maintains consistent bending precision throughout the shift. The GB-3512E is powered by GloryStar's independently developed SL100-P CNC system with a 12-inch LCD touchscreen, offering an intuitive interface and advanced sheet metal bending algorithms that reduce setup time and operator learning curve. The 4-axis CNC backgauge with AC servo motor and high-precision reducer positions automatically and avoids collision with the workpiece during the bending cycle, improving both throughput and safety.
The machine bed is welded from high-quality thick steel plate, structurally optimized through finite element analysis, and stress-relieved through high-temperature annealing — delivering high rigidity, minimal deformation, and long-term dimensional stability. Standard mechanical deflection compensation with precision-ground integral convex lower wave strips and adjustable upper wave strips ensures consistent bend angles across the full bending length. A front-mounted horizontal fine adjustment mechanism with dial indicator provides convenient, real-time compensation tuning.
The GB-3512E ships with a step-up transformer for U.S. power compatibility. Standard U.S. voltage operation: 208V or 480V 3-phase 60Hz input (transformer converts to machine-native 380V internally). No special power configuration required beyond standard industrial 3-phase service.

Why the GB-3512E Over a Hydraulic Brake?
- No hydraulic oil to change, no pumps to fail, no seals to replace
- No warm-up time — consistent accuracy from the first bend
- Lower energy consumption — servo motors only draw power under load
- Quieter operation — no hydraulic pump noise
- No oil temperature drift — same precision at 7 AM and 5 PM
- Smaller footprint than comparable hydraulic machines
- Environmentally cleaner — zero risk of hydraulic fluid leaks
