Delem, Cybelec and ESA are the three leading press brake controller brands. Delem offers the widest 2D-to-3D range (DA-53T to DA-69T), Cybelec's CybTouch is the easiest to learn, and ESA (S630 to S875) blends value with high-end 3D features. Choose based on part complexity, number of axes and budget.
The press brake controller is the single component that decides how accurate, fast and easy your bending will be. It is the CNC brain that drives the ram, positions the back gauge, calculates the bending sequence and controls the angle. When you buy a press brake, you are really choosing between three control systems - Delem, Cybelec and ESA - and getting this decision right matters more than almost any other option on the machine.
This guide compares all three brands across their full model ranges, explains the real differences between 2D and 3D control, and helps you match the right controller to your parts, your operators and your budget.
What Is a Press Brake Controller?
A press brake controller is the CNC unit - usually a touch-screen panel - that turns a hydraulic press brake into a precise bending machine. It manages several things at once:
- Ram (Y-axis) control - Drives the top beam to the exact depth needed for the programmed angle.
- Back-gauge axes - Positions the sheet for each bend (X, R, Z and more on advanced models).
- Bend-sequence calculation - Works out the order of bends and checks for collisions.
- Angle & crowning control - Compensates for material spring-back and deflection across the bed.
The main dividing line between controllers is 2D versus 3D programming, the number of axes supported, whether offline programming is available, and Industry 4.0 connectivity. Everything below comes back to those four factors.
Why does the choice matter so much? The controller directly affects three things you feel every day on the shop floor: bending accuracy (how tightly you hold the angle), setup time (how fast you go from drawing to first good part), and scrap (how many parts you spoil dialling a job in). A better-matched controller pays for itself in faster changeovers and fewer rejects - which is exactly why it deserves more attention than the tonnage sticker on the side of the machine.
2D vs 3D Programming: What Is the Difference?
2D controllers let you enter each bend by its length and angle, usually with a cross-section view of the part. They are fast, simple and perfect for brackets, panels, boxes and most everyday sheet-metal work. An operator can learn a good 2D controller in a day.
3D controllers let you draw or import the full three-dimensional part, then automatically calculate the bend sequence and check for collisions between the part, the tools and the machine before you make a single bend. For complex, multi-bend components and high-mix production, 3D simulation dramatically cuts trial-and-error and protects expensive tooling. The trade-off is a higher price and a slightly longer learning curve.
Delem vs Cybelec vs ESA at a Glance
| Brand | Entry Model | Flagship | Best For |
|---|---|---|---|
| Delem | DA-53T | DA-69T | The widest 2D-to-3D range and Industry 4.0 |

Delem Press Brake Controllers
Delem (Netherlands) is the most widely used press brake controller brand in the world, with a model for every level of work.
Delem DA-53T
The entry-level 2D controller. It has a 15.6" touch screen with "hot-key" navigation, supports up to 4 axes (Y1, Y2 plus auxiliary axes), integrated crowning control and a tool/material library. It is ideal for shops doing straightforward 2D bending.
Delem DA-58T
A step up with an 18.5" screen, 2D graphical programming and automatic bend-sequence calculation for more complex parts and faster setups.
Delem DA-66T
The popular mid-to-high-end choice. In the Delem DA-53T vs DA-66T decision, the DA-66T adds a 24" screen with full 2D and 3D graphical touch programming, 3D visualisation for simulation and production, and Industry 4.0 OPC-UA connectivity. If you bend complex, varied parts, the DA-66T is usually worth the jump.
Delem DA-69T
The flagship. Full 3D programming, an open system architecture with Profile-S offline software, and advanced shop-floor control - built for high-mix production and lights-out efficiency.
Cybelec Press Brake Controllers
Cybelec (Switzerland) is known for the Cybelec CybTouch range, prized for how quickly a new operator can learn it.
CybTouch 8
An economical, icon-based controller. Its "EasyBend" page handles quick single bends, and it automatically calculates bending angle, main pressure, deflection compensation and upper-die depth. Perfect for simple, high-efficiency bending.
CybTouch 12
The versatile mid-range unit. You can draw parts directly on the screen, it auto-calculates the best bending sequence, and it moves seamlessly from sampling to mass production.
CybTouch 15
The high-end flagship - durable and glove-compatible, with simple-touch 2D programming, large program capacity, internal backup, and remote diagnostics with laptop-free upgrades.
ESA Press Brake Controllers
ESA Automation (Italy) offers strong value across its S-series. The ESA S630 and its siblings cover everything from basic to premium 3D bending.
- ESA S630 / S640 - 2D controllers for standard bending, with an ergonomic HMI, integrated PLC and support for multiple axes - a cost-effective entry into CNC control.
- ESA S875 - The flagship, with a 21.5" frameless multi-touch screen, finger-tip workpiece design, .dxf file support, advanced tool/die library management, 3D bend visualisation and a standard Industry 4.0 Modbus TCP interface.
Delem vs Cybelec vs ESA: The Key Differences
In a practical press brake CNC controller comparison, the three brands separate on five points:
- 2D vs 3D - Delem (DA-66T/69T) and ESA (S875) lead on true 3D simulation; Cybelec focuses on fast, clean 2D.
- Ease of use - Cybelec CybTouch is the easiest for a new operator to pick up; Delem and ESA offer more depth for complex work.
- Axes & scalability - Delem scales furthest across its range; ESA and Cybelec cover most sheet-metal needs well.
- Offline programming - Delem Profile-S and ESA offline tools let you program from the office and send jobs to the shop floor.
- Industry 4.0 - Delem OPC-UA and ESA Modbus TCP make it easier to connect the machine to your production system.
A quick way to remember it: Delem gives you the deepest range and the strongest 3D and Industry 4.0 story; Cybelec wins on out-of-the-box simplicity; and ESA delivers premium features such as DXF import and 3D at a competitive price. None of them is “best” in the abstract - the right one is the one that matches the parts you actually bend.
How to Choose the Right Press Brake Controller
Weigh these factors against your real workload:
- Part complexity - simple 2D parts vs complex 3D geometry
- Production type - one-off jobs vs repeat mass production
- Number of back-gauge axes your parts need
- Operator skill level and how fast you need them productive
- Offline / office programming requirement
- Industry 4.0 and factory-network integration
- Budget and payback period

Frequently Asked Questions
1. Can I retrofit a new controller onto an older press brake?
In many cases yes - an older or NC press brake can be upgraded to a modern Delem, Cybelec or ESA CNC controller, provided the hydraulics and axes are compatible. A technician should assess the machine first to confirm feasibility and cost.
2. Are spare parts and service support for these controllers available in India?
Yes. Delem, Cybelec and ESA are all supported in India through machine suppliers and service partners, so spares, software updates and on-site service are available - always confirm local support with your machine supplier before buying.
3. Does the press brake controller come included with the machine, or is it bought separately?
On a new CNC press brake the controller is supplied and integrated with the machine as part of the package. You simply choose the brand and model that suits your work when you configure the machine.
4. How long does it take to train an operator on a CNC press brake controller?
A basic operator can learn a Cybelec CybTouch in a day or two, while the full 3D features of a Delem DA-69T or ESA S875 take longer to master. Most suppliers, including CES, provide operator training with the machine.
