Next-Gen Hybrid Servo CNC Press Brakes: Max Precision, Up to 35% Energy Savings

Empower your metal fabrication with CAMT’s Eco-Smart Hybrid Servo System. Engineered with premium Bosch Rexroth hydraulics and ESTUN closed-loop servo technology, our equipment delivers faster cycle times, ultra-quiet 50 dB operation, and over 30% oil savings—without compromising bending force or accuracy.

Hybrid ECO system

CAMT® Eco-Smart Hybrid Servo System

Engineered for high-precision, heavy-duty metal fabrication, CAMT’s Hybrid ECO System redefines press brake performance. By replacing traditional continuous hydraulic flow with a high-torque brushless servo motor and dynamic double-pump setup, the system delivers oil strictly on demand.

When the ram is idling or holding pressure, energy consumption drops near zero. During high-speed bending cycles, it dynamically regulates motor RPM to match exact tonnage requirements—slashing overall power consumption by up to 35%, cutting hydraulic oil volume by 30%, and drastically eliminating excess heat and noise in your facility.

CAMT® Hybrid Servo System Function

Experience the next evolution in metal fabrication. The CAMT® Hybrid Servo System brings together premium ESTUN closed-loop servo motors and Bosch Rexroth proportional valve technology to create a seamless, eco-smart bending platform.

  • Ultra-Responsive Servo Pump Dynamics: The pump system reads load sensors in real time, delivering high pressure instantly during the pressing cycle, and ramping down to near-zero load the millisecond the ram stops.
  • Uncompromising Repeat Consistency: Eliminates thermal displacement caused by overheating hydraulic oil, allowing your press brake to maintain uniform bending accuracy from the first piece in the morning to the last piece of the night shift.
  • Maximum Throughput with Minimum Wattage: Fast-forward and rapid return speeds are optimized via intelligent frequency control, cutting overall cycle time while using up to 35% less power than standard hydraulic models.

Why Choose CAMT® Hybrid Servo Press Brakes

Why Choose CAMT® Hybrid Servo Press Brakes

  • Boost Daily Throughput via Faster Cycle Times: Equipped with an advanced closed-loop AC servo-motor and high-dynamic hydraulics, the system accelerates ram positioning and rapid-return speeds. This minimizes non-productive waiting time between bends, drastically boosting your daily workpiece output.
  • Cut Power Bills by Up to 35%: Unlike standard hydraulic machines that consume energy 100% of the time, our closed-loop speed regulation adjusts power strictly based on actual bending tonnage. By eliminating idle power draw, you reduce overall electricity consumption by up to 35%, delivering quick ROI and lower operational costs.
  • Transform Your Shop Floor with 50 dB Acoustic Comfort: Operating at a whisper-quiet 50 dB sound pressure level, the hybrid servo drive practically eliminates the high-frequency motor whine of traditional hydraulic pumps. This creates a safer, lower-stress working environment for operators and reduces worker fatigue.
  • EU CE Certified for Global Export Standards: Full compliance with EU Directives ensures top-tier safety, electromagnetic compatibility, and eco-friendly performance. Lower energy use and extended hydraulic oil life significantly reduce your carbon footprint, helping your facility meet modern green manufacturing standards.

FAQs When Purchase CNC Press Brake Eco-Smart Hybrid Servo System

What makes the CAMT® Eco-Smart Hybrid Servo System fundamentally different from traditional hydraulic systems?
Traditional press brakes use standard AC motors that run hydraulic pumps continuously at full speed, constantly churning oil and wasting power even when idle. The CAMT® Hybrid Servo System replaces this with a high-torque brushless AC servo motor coupled with a dynamic servo pump. It operates strictly “on demand”—delivering precise oil pressure and flow only during active bending stroke, and stopping completely during operator loading or standby periods.
Energy reduction is achieved through dynamic closed-loop speed regulation. During a typical bending cycle (Fast Down $\rightarrow$ Pressing $\rightarrow$ Decompression $\rightarrow$ Rapid Return $\rightarrow$ Standby), the CNC controller calculates the exact wattage needed for each millisecond. The brushless motor drops to zero power during idle/standby and draws only proportional power during the pressing stroke, cutting cumulative daily power consumption by up to 35% compared to non-servo models.
Because the servo motor stops spinning when pressure is not required, oil friction and heat buildup are drastically minimized. Lower thermal stress allows us to design a 30% smaller, more compact fluid reservoir without risking oil overheating. Furthermore, keeping oil temperatures below $45^\circ\text{C}$ prevents thermal degradation and oxidation, effectively doubling the lifespan of the hydraulic oil and lowering fluid replacement frequency by more than 30%.
No. Traditional machines generate massive heat because excess pressurized oil bypasses relief valves continuously, requiring high-power oil chillers that consume additional electricity. Thanks to the “zero-heat at idle” nature of the Eco-Smart Servo Pump, oil temperatures remain exceptionally low even during intensive 24/7 production runs, completely eliminating the need for external oil cooling units and reducing maintenance points.
Conventional press brakes generate persistent high-frequency whine (often exceeding 75–80 dB) from continuously running gear/vane pumps. The CAMT® Hybrid System combines a smooth-running brushless AC servo motor with low-noise internal gear technology. Because the pump stops or spins at low RPMs for the majority of the cycle, ambient noise drops to an ultra-quiet 50 dB sound pressure level, creating a noticeably quiet, operator-friendly working environment.
Absolutely not. On the contrary, dynamic performance is improved. Powered by dynamic closed-loop servo control and Bosch Rexroth proportional valves, the system responds in milliseconds to pressure commands. Ram positioning repeatability reaches micron-level accuracy ($\pm 0.005\text{ mm}$), ensuring that angle consistency across complex or batch-produced workpieces is superior to traditional hydraulic press brakes.

To guarantee high durability and global reliability, the system is built with world-class components:

  • Servo Motor: High-torque closed-loop AC servo motors from ESTUN.
  • Hydraulic Valves & Manifold: Precision proportional valve technology from Bosch Rexroth (Germany).
  • Servo Pump: High-pressure, low-noise specialized servo gear pumps.
  • Linear Scales: Precision glass scales from Givi Misure (Italy) for real-time Y1/Y2 feedback.
Heat is the primary enemy of hydraulic systems; temperatures above $60^\circ\text{C}$ cause rubber seals to harden, crack, and leak, while degrading internal valve spools. By keeping hydraulic fluid consistently under $45^\circ\text{C}$, the Eco-Smart System prevents thermal stress on O-rings, polyurethane seals, and proportional valve armatures, effectively doubling the service life of internal seals and eliminating fluid leakage risks.

Depending on local electricity tariffs and daily production hours, most metal fabrication shops recover the price difference within 12 to 18 months. The payback comes from three direct financial sources:

  1. Up to 35% monthly electricity bill savings.
  2. Over 30% reduction in hydraulic oil purchase and disposal costs.
  3. Elimination of oil chiller maintenance, seal replacements, and heat-induced machine downtime.
Extremely straightforward. The system is managed via standard Delem or ESA CNC controllers, which feature built-in diagnostic screens for real-time monitoring of servo drive status, motor temperature, and valve signals. Should a replacement be needed, all core components (ESTUN servos, Bosch Rexroth valves) use standardized international mounting dimensions, enabling quick overnight express supply from CAMT or local sourcing through global distributor networks.
