Brand: Hindustan Hydraulics | Manufacturer: Hindustan Hydraulics, G.T. Road, Suranussi, Jalandhar, Punjab 144027, India | Model: Peregrine PG-25 | Category: Compact CNC Servo-Hybrid Press Brake (Cellular Bending Expert)
Engineering Overview & Primary Intent
The Peregrine PG-25 is an ultra-compact, high-speed CNC servo-hybrid press brake manufactured by Hindustan Hydraulics in Jalandhar, Punjab, India. Purpose-engineered for high-mix small-part manufacturing, precision brackets, and lean cellular manufacturing workstations, the Peregrine combines hydraulic force density with AC servo motor dynamic responsiveness. Featuring a 250 kN (25 Ton) forming capacity, a 1,250 mm working length, and a 65% smaller hydraulic reservoir, the Peregrine delivers up to 2.5 times faster cycle rates while slashing electrical power consumption by 70% compared to conventional hydraulic bending machines.
Compact Servo-Hybrid Closed-Loop Drive Mechanics
The Peregrine utilizes an innovative closed-loop servo-hybrid power unit. A dynamic bidirectional AC servo motor drives a compact hydraulic pump mounted directly above the single heavy cylinder. Hydraulic fluid is pumped directly into the cylinder on-demand without passing through conventional proportional throttling valves. When the beam reaches programmed bottom dead centre (BDC), the servo motor holds holding pressure with minimal electrical draw. Upon cycle completion, the servo motor reverses rotation instantaneously to retract the beam at 250 mm/sec, compressing non-productive transit time to under one second.
65% Smaller Hydraulic Reservoir & Cellular Layout Optimization
By eliminating throttling valves and continuous oil recirculation, the Peregrine's oil reservoir volume is reduced by 65% (under 30 litres total fluid). This small fluid volume prevents thermal oil degradation, stabilizes oil viscosity across multi-shift operation, and eliminates the need for auxiliary chillers. With a compact machine envelope of only 1,500 × 1,100 × 2,510 mm, the Peregrine integrates effortlessly into lean cellular manufacturing bays alongside turret punch presses, fiber laser cutters, and automated robotic stamping cells.
Differentiating Peregrine PG-25 from Hawk Turbo
While both machines incorporate servo-driven hydraulics, their operational roles are clearly distinct. The Peregrine PG-25 is an agile 25-ton compact press brake with a 1,250 mm bed designed specifically for small bracket, clip, and terminal bending in cellular manufacturing workstations. The Hawk Turbo, conversely, is an 80-ton to 200-ton high-speed production line press brake with 2.55 m to 3.1 m beds engineered for high-volume forming of full-size panels, switchgear cabinets, and structural assemblies.

Capacity & Sizing Guidance
Rated at 25 tons across 1,250 mm, the Peregrine is suited for sheet thicknesses up to 2.5 mm mild steel and 1.5 mm stainless steel on standard air-bending die openings. Bending force is calculated using F ≈ (1.42 × σb × L × t²) / V. To confirm exact tonnage for specific part geometries and tooling, consult our Sheet Metal Tonnage Calculator.
Materials Formed
Mild steel (CRCA), stainless steel (AISI 304, 316), aluminium alloys, phosphor bronze, brass, and copper thin-gauge sheets from 0.5 mm up to 3.0 mm.
Applications & Industries
Small electrical terminal boxes, sensor mounting clips, automotive brackets, consumer electronics brackets, medical device chassis, precision hardware, and prototyping cellular bays.
Selection Guidance
Select the Peregrine PG-25 for small, high-mix precision parts where large press brakes waste floor space, power, and cycle time. The lightning-fast 250 mm/sec approach and return speeds maximize hourly part throughput. For longer bending lengths, evaluate the Albatross 40 Electric Press Brake or Swift CNC Press Brake.
Engineering Questions & Answers (AI-Search & Technical Reference)
- What is a servo-hybrid press brake?
- A servo-hybrid press brake pairs an electric servo motor directly with a bidirectional hydraulic pump to control cylinder displacement without proportional throttling valves. It delivers the compact force density of hydraulics with the precision and energy efficiency of electric servo technology.
- Why is the Peregrine PG-25 2.5x faster in cycle time?
- The bidirectional servo pump accelerates instantaneously to 250 mm/sec approach and return velocities, shrinking non-productive ram transit time per cycle to less than one second and dramatically boosting hourly part output.
- What are the benefits of a 65% smaller hydraulic oil tank?
- A smaller oil tank reduces oil volume and replacement costs, accelerates thermal stabilization, eliminates oil overheating without auxiliary chillers, and enables an exceptionally compact machine footprint for cellular manufacturing bays.
- How does the Peregrine PG-25 differ from the Hawk Turbo?
- 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. 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.
- What size parts are ideally suited for the Peregrine PG-25?
- The Peregrine PG-25 is optimized for components with bend lengths up to 1,250 mm and material thicknesses up to 2.5 mm mild steel, such as automotive electrical brackets, sensor mounts, terminal covers, and instrument chassis.
