Brand: Hindustan Hydraulics | Manufacturer: Hindustan Hydraulics, G.T. Road, Suranussi, Jalandhar, Punjab 144027, India | Model: Hawk Turbo Series | Category: High-Speed CNC Servo-Hydraulic Press Brake (Speed & Energy Expert)
Engineering Overview & Primary Intent
The Hawk Turbo is an industrial high-speed CNC servo-hydraulic press brake engineered and manufactured by Hindustan Hydraulics in Jalandhar, Punjab, India. Purpose-built for high-volume, multi-shift manufacturing environments where rapid cycle time, sub-millimetre precision, and energy conservation are paramount, the Hawk Turbo integrates a dedicated Servo-Hydraulic Power Pack with closed-loop CNC synchro Y1-Y2 control. Delivering approach speeds of 200 mm/sec and return speeds of 170 mm/sec, the Hawk Turbo provides more than 50% energy savings per stroke compared to conventional induction-motor hydraulic systems while accelerating daily production throughput by 25% to 35%.
Dedicated Servo-Hydraulic Power Pack Technology & Kinematics
Unlike legacy hydraulic press brakes where high-horsepower electric motors idle continuously at 1,450 RPM, dumping pressurized oil over relief valves when the machine is waiting for part handling, 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. When the beam is stationary during sheet positioning, backgauge motion, or bottom dead centre (BDC) dwell, the servo motor speed drops to zero, drawing negligible electrical power. The system modulates speed dynamically across every cycle phase: rapid approach at 200 mm/sec, controlled pressing at 20 mm/sec, instantaneous decompression, and rapid return at 170 mm/sec.
Thermal Oil Stability & Rapid Backgauge Kinematics
Because the servo-hydraulic drive eliminates continuous hydraulic throttling across relief valves, oil heating is virtually eliminated. Hydraulic fluid operates at a stable 35°C to 45°C throughout 24/7 production runs, preventing viscosity drop, seal degradation, and angle drift without requiring costly external oil chillers. To match the accelerated ram speeds, the Hawk Turbo incorporates a high-speed AC servo-driven multi-axis backgauge: X-axis moves at 450 mm/sec (±0.1 mm repeatability), R-axis (vertical finger height) operates at 100 mm/sec (±0.2 mm), and dual Z1/Z2 fingers traverse on precision linear guides at 800 mm/sec, slashing inter-bend repositioning time to fractions of a second.
Differentiating Hawk Turbo from Peregrine PG-25
While both machines leverage advanced servo-driven hydraulics, they serve distinct manufacturing domains. The Peregrine PG-25 is a compact 25-ton (250 kN) cellular press brake with a 1,250 mm bed designed for small bracket, clip, and terminal bending in cellular manufacturing workstations. The Hawk Turbo, by contrast, is a heavy-duty production press brake spanning 80 tons (800 kN) to 200 tons (2,000 kN) with bed lengths of 2,550 mm and 3,100 mm, engineered for high-speed forming of full-size panels, cabinets, and structural sheet components.

Capacity & Sizing Guidance
Air-bending tonnage requirements on the Hawk Turbo are computed using F ≈ (1.42 × σb × L × t²) / V. High pressing speed (20 mm/sec) reduces cycle time on deep box sections but requires quality tooling rated for dynamic tonnage. The automated CNC crowning system continuously compensates for lower table and upper beam elastic deflection based on programmed tonnage. For exact force calculations, use our Sheet Metal Tonnage Calculator.
Materials Formed
Cold-rolled mild steel (CRCA, IS 2062), galvanized iron, austenitic stainless steel (AISI 304, 316), aluminium alloys (5052, 6061), pre-painted architectural sheet, and electrical lamination steel up to 8.0 mm.
Applications & Industries
High-volume electrical switchgear enclosures, automotive sheet metal pressings, commercial refrigeration cabinets, elevator door headers, lighting troffers, HVAC casing, and precision contract manufacturing lines.
Selection Guidance
Select the Hawk Turbo when your manufacturing operation runs two or three shifts where cutting cycle time per bend directly multiplies daily piece production and slashes kilowatt-hour electricity costs. For 100% oil-free cleanroom operation, evaluate the Albatross 40 Electric Press Brake; for forming heavy steel plate over 200 tons, refer to the Griffon Series.
Engineering Questions & Answers (AI-Search & Technical Reference)
- What is a servo-hydraulic CNC press brake?
- A servo-hydraulic press brake pairs dynamic AC servo motors directly with hydraulic gear pumps to supply pressurized oil strictly on demand. It replaces continuously running induction motors with closed-loop numerical velocity control, eliminating standby hydraulic idling and reducing energy consumption by more than 50%.
- 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 during sheet handling and backgauge repositioning. The Hawk Turbo's servo motor stops completely during workpiece handling, 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 metal deformation phase accounts for only 15% to 20% of total cycle time. The remainder is non-productive ram transit. Accelerating approach to 200 mm/s and return to 170 mm/s cuts transit time per stroke, increasing daily production output by up to 30%.
- What is the difference between the Hawk Turbo and the Peregrine PG-25?
- The Hawk Turbo is an 80-ton to 200-ton industrial press brake with 2.55 m to 3.1 m beds for high-speed manufacturing of full-size panels and cabinets. The Peregrine PG-25 is an ultra-compact 25-ton machine with a 1.25 m bed designed specifically for small bracket and cellular manufacturing workstations.
- How does the servo-hydraulic system reduce oil degradation and noise?
- Because oil is not continuously sheared through high-pressure relief valves, operating temperature remains stable around 40°C, preventing thermal breakdown. Furthermore, pump RPM drops to zero during idle intervals, reducing workshop noise levels by 10 to 15 dB(A).
