HPB-S NC Press Brakes:
Absolute Parallelism for Heavy-Duty Fabrication
The Standard for Relentless Production.
In high-volume fabrication, consistent angle accuracy relies entirely on flawless beam synchronization. The GMT HPB-S 2-Axis Servo Controlled Hydraulic Press Brake is engineered specifically to deliver this unwavering precision, stroke after stroke.
At the core of the HPB-S is a robust, hardened rack and pinion synchronization system that physically locks the left and right cylinders together, guaranteeing absolute parallelism under immense tonnage. Built exclusively for fabricators who produce standard brackets, simple profiles, or repetitive single-angle bends, this relentless production engine delivers rock-solid, repeatable power and decades of geometric stability—giving you uncompromising industrial reliability without the capital expense of a full CNC setup.
The Engineering Difference: Why Local Machines Fail
The Flaw in Standard Machines
An NC press brake relies entirely on a mechanical torsion tube to ensure the left and right cylinders move down at the exact same speed. The current market practice is to mount this tube using link-type torsion or ball-jointed torsion mechanisms. Under heavy tonnage, these joints wear out rapidly, causing the beam to permanently lose parallelism.
The GMT Rack & Pinion Solution
Our HPB-S machines utilize a unique, highly engineered synchronization system. Instead of ball joints or bush joints, we use a hardened rack and pinion system equipped with high-alloy liners. This creates a massive, unbreakable physical lock between the cylinders. It guarantees that if the left side moves 1mm, the right side moves exactly 1mm, maintaining absolute parallelism far beyond a decade of heavy use.
Core Machine Features
Servo-Motorized Backgauges
Speed dictates profitability. The HPB-S features a servo-driven backgauge that can be programmed to move automatically. It travels on high-quality ball screws and LM guideways, ensuring your operator never wastes time manually measuring the next bend position.
The "Zero Deflection" Frame
The machine frame is constructed from heavy-duty steel to withstand immense bending forces. To ensure lasting accuracy, every frame is stress-relieved and fully machined on high-accuracy floor boring machines.
TP10S Touchscreen Controller
Forget clunky keypad interfaces. The HPB-S comes standard with an intuitive TP10S Touchscreen Controller, making 2-axis programming incredibly fast and visual.
Leak-Free Hydraulics
A strong hydraulic power pack is only as good as its seals. We utilize reliable hydraulic elements and imported, high-quality seals to ensure these machines operate leak-free for years of continuous operation.
Require More Complex Bending?
The HPB-S is the ultimate workhorse for repetitive, single-angle components like standard slotted angle frames or simple brackets.
However, if your production requires complex, multi-angle geometries (like conical shapes or off-center bending) that demand 3 or more distinct bends per part, the setup time on an NC machine will bottleneck your factory. For complex geometries, you need Electro-Hydraulic Synchronization.
Technical Specifications: HPB-S Series
