Full Electric Servo Belt Drive for Everyday Precision
EPB Belt Drive is a full electric servo CNC press brake that connects the servo motor to the bending axis via synchronous belt transmission. No hydraulic power pack means no oil circuit, no pressure lag and no idle energy consumption between strokes.
Positioning accuracy reaches up to ±0.02mm with servo-driven motion and precision feedback — a solid foundation for repeatable precision bending in modern sheet metal workshops.

EPB Electric Series: Find the Right Fit
Two full electric servo CNC press brake series, each positioned for different precision and investment requirements.
EPB Belt Drive
Servo motor connected via belt transmission. A practical full-electric option with good precision at a more accessible investment level.
- Good precision at accessible investment
- Clean operation without hydraulic oil
- Energy efficient vs conventional hydraulic
- Wider workshop compatibility
EPB Direct Drive
Servo motor directly drives the bending axis. No hydraulic power pack. Best for precision and clean production environments.
- Highest precision and repeatability
- Clean room / no oil environments
- 60–80% energy saving vs hydraulic
- Fastest response and shortest cycle time
Choose HPB High-End if...
- Best for everyday industrial sheet metal bending — EPB Belt Drive is ideal if your workshop runs daily production of cabinets, enclosures, brackets and general fabricated parts, and you want cleaner, more energy-efficient electric bending at a practical investment level.
- Good for transitioning from hydraulic to electric — If you are currently using conventional hydraulic press brakes and want to move toward electric operation without the highest precision requirement, Belt Drive provides a practical step in that direction.
- Recommended for OEM and contract manufacturers — Stable CNC repeatability and clean operation make EPB Belt Drive well suited for long-term OEM contracts and contract manufacturing where consistent quality and manageable operating costs are important.

EPB Belt Drive FAQ
- Belt drive uses synchronous belt transmission between the servo motor and bending axis, providing smooth and controllable motion. Direct drive connects the motor more directly for faster response. Belt drive is generally better suited for everyday precision bending at a more accessible investment level.
- EPB Belt Drive typically consumes significantly less energy than conventional hydraulic machines, and there is no wasted energy from maintaining constant hydraulic pressure during idle periods. This makes it more cost-effective to run over long shifts and multi-day production schedules.
- The main options are ESA 875 (visual programming), DELEM DA58TX (Euro-standard), HK 68TX (cost-effective, capable) and Syntec 73BA (for unified CNC ecosystems). We recommend based on your operators, parts and production context.
- Yes. With appropriate configuration, EPB Belt Drive provides stable angle control and crowning for stainless steel enclosures and precision parts. Our team can recommend the right configuration based on your material, thickness and quality requirements.
- Belt Drive eliminates hydraulic oil circuits, reduces energy consumption, lowers noise and simplifies maintenance. It also offers better CNC repeatability and cleaner operation — making it well suited for modern workshops that want to move away from hydraulic complexity without jumping to the very highest precision level.
