HSB Series:
The Definite Standard for High-Volume Straight Cutting
Engineered for Rigidity. Built for Speed.
In every sheet metal shop, the shearing machine is the foundation of production. While modern manufacturing is evolving, the need for a machine that can deliver rapid, clean, and perfectly straight cuts across large formats remains a necessity.
The GMT HSB Series Hydraulic Swing Beam Shearing Machine is designed to be the “relentless engine” of your cutting department. Utilizing a robust, stress-relieved steel frame and a high-dynamic hydraulic system, the HSB Series ensures that every cut is as accurate as the first, year after year.
The Engineering of a Superior Cut
Four pillars of design that make the HSB Series the benchmark for straight-line shearing.
Robust Frame & Stress-Relieved Structure
A shearing machine is only as good as its frame. The HSB Series body is duly stress-relieved through a thermal process to ensure the machine never warps or 'relaxes' under the immense force generated during cutting. This structural integrity is what allows GMT machines to maintain accuracy for decades.
High-Performance Hydraulic System
Our machines utilize world-class hydraulic power packs integrated with an efficient hold-down system. These hold-downs apply firm, even pressure to the workpiece before the blade moves, preventing sheet slippage and ensuring a burr-free edge. High-quality, imported seals ensure the cylinders remain leak-proof even under heavy 24/7 operation.
Nitrogen Cylinder Quick-Return
To maximize your strokes per minute, the HSB Series is equipped with Nitrogen Return Cylinders. This system uses the compression of nitrogen to retract the ram to its original position instantly after a cut is completed, significantly reducing cycle times compared to standard spring-return machines.
Precision Blade Clearance Adjustment
Different materials require different tolerances. The HSB features an easily accessible manual blade clearance adjustment. This allows your operator to quickly dial in the perfect gap between the upper and lower blades based on the thickness and tensile strength of the sheet, preventing edge deformation and extending the life of your steel blades.
Evolution of the Cutting Floor: Beyond the Straight Line
The HSB Series remains the king of high-volume straight shearing. However, as fabrication grows more complex, manufacturers are increasingly moving toward Shearing Machine to handle intricate geometries, high-density nesting, and zero-tooling costs.
If your production roadmap requires more than just straight cuts — and the ability to cut complex shapes in a single pass — it is time to explore the future of cutting.

Every element of the HSB Series is tuned for precision, repeatability, and operator efficiency.
ESTUN E21S NC Controller
Features a proven control system to ensure quick and accurate positioning of the motorized backgauge. It allows for easy programming of cut lengths and stroke counts, reducing operator error.
Servo-Motorized Backgauge
The backgauge moves on high-quality ball screws and LM guideways, ensuring that your sheet is positioned with micron-level repeatability.
Sheet Drop System
To enhance shop floor efficiency, a dedicated drop is provided behind the shear. This ensures that cut pieces are automatically collected at the back of the machine, keeping the front clear for the next sheet.

Frequently Asked Questions
01Can the HSB Series cut stainless steel?
Yes. The high-quality tool steel blades are designed to handle various materials. However, when cutting stainless steel, the blade clearance must be adjusted specifically to account for the material's higher tensile strength to ensure a clean cut.
02Is a foundation pit required for these machines?
Most of our standard HSB models are designed for floor-level installation. However, for ultra-large format shears (e.g., 6000mm length), a foundation pit may be recommended to ensure absolute stability. Please consult with our site engineers for your specific layout.
03What is the benefit of the "Swing Beam" design?
The swing beam design allows the upper blade to move in a slight arc. This reduces friction during the cut and allows the cut piece to drop away more easily, resulting in less distortion in the finished strip compared to vertical guillotine shears.
