Servo Electric Press Brakes

Why Go Electric

The Case for Servo Drive

Servo electric press brakes aren't just hydraulic machines without the oil — they represent a fundamentally different approach to bending that delivers real production advantages.

⚡

Zero Hydraulic System

No hydraulic oil, no hoses, no seals, no pump, no oil changes. Eliminate the single largest maintenance source on a traditional press brake. The servo motor drives the ram directly — cleaner, simpler, more reliable.

📌

Up to 50% Energy Savings

A hydraulic pump runs continuously during operation regardless of whether the ram is moving. Servo motors only draw power on demand — during actual bending motion. The energy savings add up fast at production volumes.

🔇

Quieter Shop Floor

No hydraulic pump means significantly lower noise levels during both idle and active cycles. Operators work in a noticeably quieter environment — important for multi-shift production and operator wellbeing.

⏳

Faster Cycle Times

Servo motors respond instantly and accelerate faster than hydraulic systems. Approach, bending, and return speeds are all faster — delivering 35% improvement in cycle times over comparable hydraulic machines.

🎯

Higher Repeatability

Direct servo drive eliminates hydraulic pressure variation and thermal drift. The ram position is servo-controlled to micron-level precision — bend after bend, without warm-up periods or mid-shift recalibration.

🆘

Cleaner Production Area

Hydraulic oil contamination risk is eliminated. Suitable for food processing equipment fabrication, medical device manufacturing, and other industries where oil leaks pose a serious production or compliance risk.

Dener Series

Servo Electric Models

Two servo electric series from Dener — engineered for different production profiles. Both are 100% hydraulic-oil-free with servo motor direct drive.

Dener

DDM Series

DDM Servo Electric Press Brake

The DDM (Direct Drive Motor) series is Dener's primary servo electric platform. Servo motors drive the ram directly with no mechanical transmission losses — delivering precise, repeatable bending with fast cycle times. Available in multiple tonnage and bed length configurations up to 200T.

DDS Series

DDS Servo Electric Press Brake

The DDS series offers a compact servo electric solution for shops transitioning from hydraulic to electric drive. The same zero-oil, servo-motor precision as the DDM series in a footprint-optimized configuration. Suited for medium-volume production where floor space and energy efficiency are priorities.

Key Features

Built for Precision & Efficiency

🎯

ESA S 530 CNC Control

Graphical 2D programming with automatic bend sequence calculation. Program complex parts in minutes. Stores hundreds of part programs with tool and material libraries pre-loaded.

⚡

Servo Motor Direct Drive

The servo motor drives the ram directly — no hydraulic conversion, no pressure variation, no thermal drift. Ram position is servo-controlled to ±0.01 mm throughout the full stroke.

📌

Energy on Demand

Power is consumed only during actual ram movement. Idle periods and backgauge repositioning draw minimal current. Real-world energy savings of 40–50% vs. hydraulic are consistently measured in production.

🔧

4-Axis Back Gauge

Standard 4-axis (X, R, Z1, Z2) back gauge on DDM series provides precise sheet positioning for complex bending sequences. Motorized stops with position feedback ensure consistent part accuracy.

🚫

Light Curtain Safety Standard

CE and CSA certified light curtain protection included as standard. The guarding system meets EN 12622 press brake safety requirements — no additional safety upgrades required for Canadian market deployment.
