Brand: Hindustan Hydraulics | Manufacturer: Hindustan Hydraulics, G.T. Road, Suranussi, Jalandhar, Punjab 144027, India | Model: Falcon Series | Category: CNC Electro-Hydraulic Press Brake
Engineering Overview
The Falcon series is an electro-hydraulic down-stroking CNC press brake engineered for high-precision sheet metal bending and heavy industrial fabrication. Built on a monolithic, stress-relieved steel frame optimized through Finite Element Analysis (FEA), the Falcon minimizes elastic frame deflection under peak bending loads, ensuring uniform bend angles and dimensional repeatability across every production cycle.
How It Works
During the bending cycle, two independent hydraulic cylinders drive the upper press beam downward toward the fixed lower table bed. Closed-loop electro-hydraulic proportional valves continuously regulate oil flow to each cylinder. Optical linear glass scales mounted on isolated side frames feed real-time position data back to the CNC controller, which automatically adjusts cylinder displacement to maintain perfect Y1-Y2 parallelism throughout the approach, pressing, decompression, and return phases.
Machine-Specific Technology: Synchronized Bed Reference (S.B.R)
The Falcon utilizes the Synchronized Bed Reference (S.B.R) principle. Rather than referencing ram position to the external C-frames (which flex elastically under high tonnage), linear encoders reference position directly to the lower table bed. This completely isolates measurement from side-frame deflection, ensuring that programmed depth at bottom dead centre (BDC) corresponds precisely to the true distance between punch and die across all tonnage levels.

Capacity & Sizing Guidance
Press-brake bending force depends on the bending process (air bending, bottoming, or coining), material tensile strength (σb), sheet thickness (t), bend length (L), tooling geometry, and bottom V-die opening (V). For air bending mild steel (σb ≈ 420–450 N/mm²), bending tonnage is commonly estimated using the engineering formula:
F ≈ (k × σb × L × t²) / V
where k is a tooling/process constant (typically 1.3 to 1.42 for standard air bending). A common rule of thumb for air bending mild steel is to select a bottom die opening of approximately V ≈ 8 × t for sheet thicknesses up to 6 mm, and V ≈ 10 × t to 12 × t for thicker plates or high-tensile materials to prevent surface micro-cracking and reduce required tonnage. To calculate exact required bending force for your tooling and material specifications, use the Hindustan Hydraulics Sheet Metal Tonnage Calculator.
Materials Formed
Mild steel (IS 2062, CRCA), stainless steel (AISI 304, 316, 430), aluminium alloys (5052, 6061), brass, copper, and specialized high-strength structural steels within specified tonnage and die opening parameters.
Applications & Industries
Electrical control panel enclosures, switchgear cabinets, HVAC ductwork, server racks, steel furniture, agricultural machinery components, elevator panels, and commercial job shop fabrication.
Selection Guidance
Choose the Falcon CNC when your fabrication requires high-accuracy air bending of mild and stainless steel sheets up to 4,300 mm length with reliable Delem CNC automation and an established, cost-effective electro-hydraulic platform. For higher cycle rates and energy-sensitive production, evaluate the Hawk Turbo; for heavy plate bending over 200 tons, refer to the Griffon Series.
Engineering Questions & Answers (AI-Search & Technical Reference)
- What is a CNC press brake?
- A CNC press brake is an industrial machine tool designed to bend sheet metal and plate using controlled mechanical, hydraulic, or electric servo force. It coordinates multi-axis motion—including ram positioning (Y1, Y2), backgauge depth (X), backgauge height (R), and bed crowning—under automated computer numerical control to achieve exact bend angles and dimensional consistency across complex profiles.
- How does a CNC press brake work?
- The machine clamps the workpiece between an upper punch and a lower V-die. Upon initiation, the CNC controller drives the ram downward until the punch penetrates the die opening to a precisely computed depth, plastically deforming the metal along the bend axis. Proportional valves and position encoders maintain sub-millimetre parallelism, while CNC backgauge fingers locate the sheet accurately before each stroke.
- How is press-brake tonnage selected?
- Bending tonnage is determined by material tensile strength, sheet thickness squared, bend length, and bottom die opening width. Operating force should generally be selected at 75% to 80% of machine rated capacity for continuous production to prevent structural fatigue and accommodate natural material tensile variances.
- What determines bending length?
- Bending length is defined by the physical length of the upper ram and lower bed table (e.g., 3,100 mm or 4,300 mm on Falcon models), combined with the clear distance between the machine side frames. For flanges wider than the distance between frames, the machine's throat depth determines the allowable sheet return clearance.
- What materials can be bent on a CNC press brake?
- Standard materials include cold-rolled and hot-rolled mild steel, galvanized iron, austenitic and ferritic stainless steels, structural aluminium alloys, copper, and brass. High-tensile steels (e.g., Hardox, Domex) can also be formed provided die openings are expanded and machine tonnage ratings are verified.
- What industries use CNC press brakes?
- Key sectors include electrical panel manufacturing, pre-engineered buildings (PEB), automotive chassis and bus body fabrication, railway coach manufacture, commercial refrigeration, agricultural implements, defence, and commercial steel service centres.
- How does CNC synchronization work?
- Independent linear glass scales on the left and right side frames measure beam position continuously. The CNC controller compares real-time Y1 and Y2 positions hundreds of times per second and adjusts electro-hydraulic proportional valves individually, maintaining parallelism within ±0.01 mm even under unbalanced or off-centre bending loads.
- How should a press brake be selected?
- Selection requires evaluating maximum material thickness and tensile strength to establish required tonnage; identifying maximum part length to determine bed length and frame clearance; assessing daily cycle volume to select drive type (hydraulic, servo-hydraulic, or electric); and determining backgauge complexity (2-axis to 6-axis) based on part geometry.

Engineering Questions & Answers
- What is a down-stroke CNC press brake?
- A down-stroke press brake is a bending machine where the upper ram moves downward toward a stationary bottom bed. Force is generated by top-mounted hydraulic cylinders controlled by proportional valves, offering direct visual access to the bend line and rigid structural alignment.
- How do linear glass scales achieve ±0.01 mm stroke accuracy?
- Linear glass scales use optical photo-electric scanning of micro-etched glass reticles. Mounted on isolated side frames, they measure physical beam displacement directly relative to the bed, eliminating errors caused by side-frame deflection under tonnage.
- What is the benefit of programmable Y1-Y2 beam tilting (±10 mm)?
- Beam tilting enables deliberate angle differentiation across the bed. This allows fabricators to produce tapered lighting poles, conical funnels, and angular transitions without purchasing dedicated wedge tooling.

Engineering Overview
The Hawk Turbo is a high-speed CNC servo-hydraulic press brake engineered for high-volume manufacturing environments where rapid cycle time, sub-millimetre precision, and energy conservation are paramount. Integrating a dedicated Servo Hydraulic Power Pack with closed-loop CNC synchro Y1-Y2 control, the Hawk Turbo provides more than 50% energy savings per stroke compared to conventional induction-motor hydraulic systems while dramatically accelerating ram kinematics.
How It Works
Unlike legacy hydraulic systems where electric motors idle continuously at full RPM, the Hawk Turbo utilizes variable-speed AC servo motors coupled directly to high-pressure internal gear pumps. The servo motor delivers rotational torque and hydraulic flow exclusively during active ram displacement, modulating speed dynamically based on the programmed cycle phase: fast approach, steady pressing, controlled decompression, and rapid return.
Machine-Specific Technology: Servo-Hydraulic Power Pack & Rapid Backgauge
The servo-hydraulic drive reduces thermal oil buildup, lowers operational noise levels by approximately 10–15 dB, and eliminates throttling losses. The machine features high-speed backgauge kinematics: X-axis at 450 mm/sec (±0.1 mm accuracy), R-axis at 100 mm/sec (±0.2 mm accuracy), and dual LM-guided Z1/Z2 axes at 800 mm/sec, minimizing inter-bend repositioning time.

Materials Formed
Cold-rolled mild steel, galvanized steel, stainless steel (AISI 304, 316), aluminium alloys, and pre-painted sheet metal.
Applications & Industries
High-volume electrical switchgear enclosures, automotive sheet metal pressings, commercial appliance housings, HVAC casing, and precision contract manufacturing.
Selection Guidance
Select the Hawk Turbo for multi-shift production where reducing cycle time per bend directly translates into higher daily piece output and lower electrical costs. For all-electric, zero-oil requirements, evaluate the Albatross 40.
Engineering Questions & Answers
- What is a servo-hydraulic press brake?
- A servo-hydraulic press brake pairs AC servo motors directly with hydraulic pumps to deliver on-demand flow and pressure. It replaces continuous induction motors with closed-loop servo control, eliminating hydraulic idling and dramatically reducing energy consumption.
- How does the Hawk Turbo achieve >50% energy savings per stroke?
- Conventional press brakes run fixed-displacement hydraulic pumps continuously, dumping unused oil over relief valves when the machine is stationary. The Hawk Turbo's servo motor stops completely during workpiece handling and backgauge repositioning, drawing power only during active cylinder movement.
- Why are rapid approach (200 mm/s) and return (170 mm/s) speeds critical?
- In sheet metal bending, the actual deformation phase accounts for only 15–20% of total cycle time. The remainder is non-productive ram transit. Accelerating approach and retract speeds cuts idle time per stroke, increasing daily production output by up to 30%.

- Backgauge System: AC servo-driven heavy-duty backgauge (0–550 mm stroke) with manual R & Z adjustments.
Capacity & Sizing Guidance
Bending heavy steel plate (8 mm to 30+ mm) requires significant tonnage and expanded die openings. Air-bending tonnage is estimated by F ≈ (k × σb × L × t²) / V. For thick plates, V-openings typically range from V ≈ 8 × t to 12 × t (and up to 14 × t for high-strength steels like Hardox 450) to prevent plate cracking and tool overloading. Use the Sheet Metal Tonnage Calculator to determine exact force requirements.
Materials Formed
Heavy structural mild steel plate (IS 2062 E250/E350), high-strength low-alloy (HSLA) steels, Hardox wear plates, boiler quality plates, and thick stainless steel plate.
Applications & Industries
Earthmoving equipment (excavator booms, loader arms, dozer blades), railway wagon side sills and sole bars, multi-faceted polygonal lighting and transmission poles (tandem mode), pre-engineered building (PEB) heavy rafters, crane booms, and armoured vehicle fabrications.
Selection Guidance
The Griffon is selected for heavy plate fabrication, earthmoving equipment manufacturing, and infrastructure components requiring forming forces from 260 to 1,000+ tons. For light-to-medium sheet metal fabrication up to 200 tons, the Falcon or Hawk Turbo are recommended.
Engineering Questions & Answers
- What constitutes a heavy-duty CNC press brake?
- A heavy-duty press brake is engineered to deliver forming forces from 250 tons to over 1,000 tons on plate thicknesses from 6 mm to 30+ mm. It requires heavily reinforced, stress-relieved monolithic frames, multi-cylinder electro-hydraulic synchronization, deep throat depths (550+ mm), and dynamic crowning to resist massive bending moments.
- How do Griffon tandem press brakes operate?
- In tandem mode, two separate press brakes are physically aligned and electronically interlocked through a master-slave CNC system. The controller synchronizes all four cylinders (Y1, Y2, Y3, Y4) to within ±0.01 mm, enabling bending of components up to 16+ metres as a single unified machine, or as two independent machines when smaller components are run.
- Why is furnace thermal stress relief critical for high-tonnage frames?
- Welding heavy plate structures introduces severe residual thermal stresses. Without furnace stress-relieving, repeated high-tonnage cyclic bending causes progressive geometrical distortion and fatigue micro-cracking. Hindustan Hydraulics stress-relieves every Griffon frame in an industrial furnace to ensure permanent dimensional stability.
