1. What Is the Delem DA-66S?

The Delem DA-66S is a modular high-end press brake CNC in the DA-60S family. It is designed for sophisticated press brake applications that need accurate machine control, a large touch interface, flexible machine integration, and advanced production support.

Delem describes the DA-66S as a 2D graphical front-end CNC. Product programming is performed in 2D, while the controller provides a full 3D representation of the machine during simulation and production.

This distinction matters. The DA-66S is not positioned as Delem's 3D product-programming model; that role is associated with the DA-69S. The DA-66S instead combines efficient 2D product programming with 3D machine feedback so operators can evaluate feasibility, handling, tooling, and collision risk.

The controller uses Delem's renewed touch interface, allowing direct navigation between programming and production. Functions are placed where they are needed in the workflow to reduce unnecessary menu navigation.

The DA-66S is particularly suitable for premium electro-hydraulic press brakes, multi-axis machines, machines with advanced backgauges, sensor-bending systems, part supports, tandem applications, and other configurations where modularity and integration matter.

The real value of the DA-66S is not only the screen. It is the combination of control algorithms, modular architecture, graphical workflow, machine representation, and integration with high-end press brake functions.

2. DA-66S Features and Technical Specifications

Delem's current DA-66S technical data lists a 24-inch high-brightness color TFT display with 1920 × 1080 Full HD resolution, industrial PCT touchscreen control, LED backlighting, and 3D graphics acceleration.

The controller provides 4 GB of storage capacity and 3 GB of product and tool memory. Standard Windows networking and USB flash memory are included.

Standard functional highlights include 2D graphical touchscreen programming, full 3D machine representation in simulation and production, Modusys compatibility, USB and peripheral interfacing, user-specific application support within the multitasking environment, sensor-bending and correction interfaces, and Profile-S2D offline software.

Delem lists a range of options including part-support control, X1-X2 angle programming, barcode reader interfacing, protractor interfacing, frame-deflection compensation, sheet-thickness measurement and compensation, TandemLink, a second HSB Modusys bus, an additional control panel, and an OPC UA interface for Industry 4.0 connectivity.

The DA-66S is therefore designed not only as a user interface but as a scalable platform that machine builders can adapt to sophisticated press brake configurations.

3. 2D Programming vs Full 3D Machine Representation

One of the most important things to understand about the DA-66S is the difference between product programming and machine visualization.

The DA-66S provides 2D graphical product programming. The operator creates and edits the product profile in a two-dimensional graphical environment.

During simulation and production, the DA-66S provides a full 3D representation of the press brake machine. This allows the operator to see the machine, tooling, workpiece, and handling situation in a more realistic way.

This combination gives the operator a simple 2D programming workflow while still providing rich 3D feedback about feasibility and machine interaction.

For companies comparing the DA-66S with the DA-69S, this distinction is important. The DA-69S is Delem's 3D graphical front-end CNC, while the DA-66S remains a 2D graphical programming control with 3D machine representation.

For many fabrication shops, 2D product programming is faster and easier for the majority of sheet metal parts, while 3D machine simulation provides enough visual information to verify the production process.

4. Delem Modusys and Modular Machine Control

The DA-60S family is built around Delem's Modusys architecture. Modusys allows machine builders to scale axes, I/O, and real-time interfaces according to the application.

This modular approach is valuable on high-end press brakes because different customers may need very different machine configurations. One machine may use a relatively simple backgauge, while another may use multiple auxiliary axes, front supports, sensor-bending systems, or specialized automation.

Delem states that Modusys can add Y axes, auxiliary axes, I/O expansion, and real-time interfacing for functions such as sensor bending.

The architecture also allows distributed I/O and autonomous subassemblies to be added through power supply and HSB-bus connectivity.

For the machine buyer, the practical message is that the DA-66S is designed to grow with complex machine requirements. However, only the axes and modules actually installed on your press brake are available to the operator.

When requesting a quotation, ask the machine supplier to list the complete axis configuration and included Modusys modules rather than relying only on the DA-66S controller name.

5. Hardware and Machine Integration

The DA-66S uses a large 24-inch industrial touchscreen, giving operators substantial screen space for product programming, machine visualization, tool information, and production guidance.

Above the display, Delem reserves a panel area for machine functions and OEM application switches. The actual functions located in this panel depend on how the press brake manufacturer integrates the machine.

The controller runs on an embedded real-time Linux operating system, which Delem uses across the DA-60S family to provide reliable and smooth machine start-up and operation.

The control communicates with the press brake's hydraulic or drive system, encoders, backgauge axes, crowning or deflection systems, sensors, I/O, safety-related machine circuits, and optional production aids.

Because the control is deeply integrated into the machine, an alarm shown on the DA-66S can originate from many places. A drive, sensor, encoder, hydraulic function, limit, I/O signal, or machine option may be the real source.

Internal electrical work, safety-system modification, Modusys configuration, drive tuning, and hydraulic synchronization should only be performed by qualified service personnel.

6. User Interface and Touch Navigation

The DA-66S uses Delem's touchscreen navigation philosophy to move directly between programming and production.

Functions are located close to where they are needed in the workflow. This reduces unnecessary menu navigation and allows operators to move quickly from a product definition to tooling, sequence calculation, simulation, and production.

The large Full HD screen makes it easier to see product geometry, tool stations, machine representation, axes, and production instructions.

Before starting a cycle, operators should verify the active product, current bend step, selected tooling, axis positions, machine status, and any active correction.

Warnings and alarms should be read before they are cleared. Record the exact message and machine state if the problem may require technical support.

Machine builders can add OEM-specific functions, so two DA-66S machines may have different switches, pages, options, or axis displays.

7. Startup and Axis Referencing

Before starting the press brake, inspect the working area and remove loose parts, tools, measuring devices, and other objects that could interfere with machine motion.

Follow the machine builder's specified startup procedure. This normally includes powering the machine, allowing the controller to boot, releasing emergency stops when safe, enabling the hydraulic or drive systems, verifying safety functions, and referencing axes where required.

Referencing establishes a known physical position for an axis. If the machine requests referencing, complete the approved procedure before production.

Advanced machines may have several auxiliary axes, supports, or additional mechanisms. Make sure all required systems reach their ready state before running a product.

Before loading a saved program, verify the product revision, material, actual thickness, tools, tool station, and backgauge setup.

Perform a controlled first piece and measure the bend before releasing the job for full production.

8. How to Program the Delem DA-66S

Start with the correct drawing revision and confirm material grade, thickness, bend angles, flange dimensions, inside radius requirements, and tolerances.

Create or select the product using a clear naming convention. A good system can include customer code, part number, revision, and material.

Program the product graphically in 2D. Verify every flange direction and bend relationship against the drawing.

Select the actual punch and die geometry from the tool library. The simulation is only useful when the tool data reflects the real tools installed in the machine.

Select the correct material and enter the actual thickness where required. Material strength and thickness variation influence springback and bending results.

Use automatic bend-sequence calculation to prepare a production sequence. Review the result rather than assuming the first calculated sequence is always ideal for real-world handling.

Use the 3D machine representation to evaluate feasibility, tool stations, machine clearance, part handling, and collision risk.

Run a measured first bend, apply controlled production corrections, and save the final proven program so repeat orders can start from a known setup.

9. Automatic Bend-Sequence Calculation

The DA-66S includes automatic bend-sequence calculation as part of its 2D programming workflow.

A multi-bend part can often be produced in several different sequences, but some sequences are inefficient or physically impossible because an earlier flange blocks a later bend.

The controller uses the programmed product, tooling, and machine information to calculate a sequence and evaluate feasibility.

Automatic sequencing can reduce setup time and make complex parts easier to program, particularly when operators are less familiar with a part.

The calculated sequence should still be reviewed. Part weight, surface finish, operator ergonomics, support requirements, and shop-specific handling preferences may influence the preferred sequence.

If the operator changes the sequence manually, run simulation again and verify every bend before production.

10. Collision Detection and 3D Machine Simulation

The full 3D machine representation is one of the strongest features of the DA-66S.

During simulation, the controller can display the machine, product, and tooling to give feedback on production feasibility and handling.

Collision detection is especially valuable on parts with return flanges, deep boxes, gooseneck tooling, multiple tool stations, or complex rotations.

Simulation is only as accurate as the data in the system. Incorrect machine dimensions, tool geometry, adapters, or product geometry can make the digital representation differ from reality.

Treat collision detection as an important programming aid, not as a replacement for physical setup verification or machine safety systems.

Before the first bend, confirm that the actual tools, adapters, workpiece orientation, and machine clearances match the simulated setup.

11. Multiple Tool Stations

The DA-66S supports a full 3D machine setup with multiple tool stations, allowing the operator to visualize different tooling arrangements across the machine.

Multiple tool stations can reduce setup time when a part requires different punches or dies for different bend steps.

Instead of changing the complete tool setup between operations, the operator can move the part to the required station when the machine and product design allow it.

Tool stations must be represented accurately in the control. The installed segment lengths, positions, punch profiles, dies, and adapters should match the digital setup.

Always verify that the workpiece can be handled safely between stations and that neighboring tools do not create unexpected collision risks.

For high-mix production, standardized tool stations can be an effective way to reduce daily setup time.

12. Tool Library: Punches, Dies and Adapters

The tool library stores the geometries used for programming, sequence calculation, and simulation.

Punch data can include height, angle, tip radius, profile shape, and segmentation. Gooseneck tools require accurate geometry because their profile affects flange clearance.

Die data should accurately represent the V-opening, height, angle, and shape. V-opening strongly affects tonnage, natural inside radius, and minimum flange.

Tool adapters should also be represented correctly when they influence the total tool height or clearance.

Use tool names that match physical labels on your tooling racks. A clear naming system reduces setup errors and helps operators find the correct tools quickly.

Inspect actual tooling before production. Worn or damaged tools can produce poor results even when the controller library is perfectly accurate.

13. Material Library, Thickness and Springback

Material properties are a major source of variation in press brake bending.

Mild steel, stainless steel, aluminum, and high-strength materials do not bend the same way even when sheet thickness is identical.

Stainless steel generally requires more force and shows greater springback than comparable mild steel.

Aluminum varies widely by alloy and temper. Some grades can tolerate tight bends while others require larger bend radii to avoid cracking.

Springback is the elastic recovery that occurs after bending force is removed. It depends on material strength, thickness, tooling, bend radius, and bending method.

The DA-66S can be integrated with optional sheet-thickness measurement and compensation systems. This can be useful on demanding applications where incoming sheet thickness variation affects accuracy.

Build a material database that reflects the grades your shop actually uses and preserve stable production corrections when they are repeatable.

14. Axes and Backgauge Programming

The DA-66S is designed for modular high-end machines, so the exact axis configuration can vary significantly from one press brake to another.

Y1 and Y2 normally control the synchronized sides of the ram. Auxiliary axes may control backgauge depth, vertical movement, lateral finger positions, independent gauge movement, part supports, or other machine functions.

Delem lists X1-X2 angle programming as an option. This is useful on suitable backgauge systems where independent gauge positions are required.

Because the DA-60S architecture is modular, additional axis functionality can be added through Modusys according to the machine design.

Do not assume that every DA-66S press brake has the same axes. Check the technical specification supplied by the machine manufacturer.

If a flange dimension is wrong, determine whether the error is repeatable or random. A stable offset can indicate program or calibration issues, while random error often points to gauging contact, handling, or mechanical play.

15. Crowning and Frame-Deflection Compensation

Long press brake bends can show angle variation because the machine frame, bed, ram, and tooling deflect under load.

Crowning compensates for this deflection so the bend angle is more uniform along the workpiece.

Delem also lists advanced frame-deflection compensation as an option for the DA-66S.

If the ends of a long bend are correct but the center is too open, crowning or deflection compensation is a logical area to investigate.

If the complete part is equally open or closed, a general bend correction may be more appropriate.

Measure several points along the bend before changing compensation. Tool seating, machine alignment, material variation, and tool wear can also create angle differences.

16. Sensor Bending and Correction

The DA-66S includes sensor-bending and correction interfacing as a standard controller feature, with the actual sensor system depending on machine integration.

Sensor bending allows a compatible measurement system to provide bending information back to the control so that the process can be corrected.

This can reduce dependence on trial bends and help compensate for material variation in demanding production environments.

Delem also lists protractor interfacing and sheet-thickness measurement and compensation as optional aids.

The benefit of sensor bending depends on the actual sensor hardware, calibration, tooling, machine configuration, and production requirements.

Buyers interested in angle measurement or automatic correction should ask the machine supplier exactly which sensor system is included and how it is integrated with the DA-66S.

17. Production Mode and Operator Guidance

After the product, tools, bend sequence, and machine setup are verified, the DA-66S provides graphical production guidance using its 3D machine representation.

The operator can follow the bending sequence while seeing the machine and product configuration on the large screen.

This visual guidance is especially useful when a part must be rotated, flipped, moved between tool stations, or positioned differently for each bend.

Before cycle start, verify the active product, revision, material, thickness, tooling, station, bend step, and machine-ready state.

Measure the first parts and define an appropriate inspection frequency for the production batch.

If corrections begin drifting during production, investigate material changes, tooling, temperature, support conditions, and machine state before applying increasingly large corrections.

18. USB, Networking, Barcode and Industry 4.0 Options

The DA-66S includes standard Windows networking and USB flash memory support.

Networking can simplify product transfer between engineering, offline programming stations, and the press brake, but the company should maintain revision control and access permissions.

USB storage is useful for backup and data exchange. Use a reliable drive reserved for machine data and keep an additional backup outside the machine.

Barcode reader interfacing is listed as an option. In suitable production environments, barcode-based product selection can reduce manual program-selection errors.

Delem lists an optional OPC UA interface for Industry 4.0 integration. This can support structured communication with higher-level manufacturing systems when configured.

Connected functions should be implemented together with the machine supplier and the customer's IT or automation team.

19. Profile-S2D Offline Programming

Delem lists Profile-S2D as the offline software for the DA-66S.

Offline programming allows production preparation to be performed away from the press brake so the machine can continue bending while future jobs are being prepared.

The offline workflow can be used for product programming, tooling verification, bend-sequence preparation, simulation, production notes, and operator training.

Accurate offline programming requires an accurate representation of the actual press brake, tools, and machine options.

Use revision control when programs can be edited both offline and at the machine. Operators should always know which version is approved for production.

On high-mix production, moving programming and feasibility work away from the machine can significantly improve press brake utilization.

20. Preventive Maintenance

Keep the 24-inch touchscreen clean and free from abrasive workshop contamination.

Inspect the press brake daily for visible leaks, unusual noise, damaged tooling, backgauge problems, and safety-device issues.

Follow the machine manufacturer's hydraulic oil, filtration, cooling, lubrication, and electrical cabinet maintenance requirements.

Check electrical cabinet filters and fans at the specified interval. Excess heat can reduce the life of electronic components and drives.

Back up product and tool data regularly and after important configuration changes.

Do not perform random machine-parameter changes when troubleshooting. Modusys settings, sensor interfaces, drive tuning, safety systems, and hydraulic synchronization should be handled by trained service personnel.

21. DA-66S Troubleshooting Guide

Troubleshooting should begin with a precise symptom. Record the exact alarm, machine mode, active product, axis positions, and what happened immediately before the problem.

If the machine will not start, check emergency stops, safety functions, machine-ready status, active alarms, hydraulic or drive state, and required axis references.

If a bend sequence looks impractical, verify the product geometry, tool data, tool station layout, machine representation, and any manual sequence changes.

If a collision warning appears, do not simply bypass it. Review the programmed geometry, tooling, adapters, machine clearance, and part orientation.

If a flange dimension is wrong, verify the programmed backgauge target, calibration, finger position, and actual workpiece contact.

If bend angle is wrong, check actual material thickness, material strength, tooling, corrections, sensor data where fitted, and crowning or deflection compensation.

Random service-parameter changes should be avoided. High-end machines can have complex interaction between axes, sensors, I/O, hydraulics, and machine modules, so documented diagnosis is essential.

22. DA-66S vs DA-58TX vs DA-69S

The DA-58TX is a high-feature compact DA-50Touch controller with 2D graphical programming, sequence calculation, collision detection, and an 18.5-inch display.

The DA-66S moves into Delem's modular DA-60S platform. It keeps 2D graphical programming but adds a 24-inch Full HD screen, full 3D machine representation, Modusys compatibility, advanced integration, sensor-bending interfaces, and extensive machine options.

The DA-69S is the 3D graphical front-end CNC in the DA-60S family. It is intended for users who want 3D product programming in addition to the high-end modular machine platform.

For many production environments, the DA-66S provides an excellent balance: efficient 2D product programming with sophisticated 3D machine feedback and high-end machine integration.

The correct choice depends on part complexity, machine architecture, desired programming method, automation, sensor requirements, and budget.

For more detail on the compact controllers, read our DA-53T guide, DA-53TX guide, and DA-58TX guide.

23. Who Should Choose the DA-66S?

The DA-66S is a strong choice for manufacturers purchasing a high-end press brake with a sophisticated axis configuration or advanced machine functions.

It is particularly suitable when the machine includes multiple backgauge axes, part supports, sensor bending, special compensation systems, multiple tool stations, or other functions that benefit from modular integration.

Companies that prefer fast 2D product programming but still want a full 3D machine representation can find the DA-66S especially attractive.

The large 24-inch Full HD screen is useful in production environments where operators need a clear view of complex tool setups, machine geometry, and product handling.

For simpler press brakes, the DA-53TX or DA-58TX may provide sufficient capability at lower cost.

If 3D product programming is a key requirement, compare the DA-69S. Always choose the controller together with the complete press brake specification rather than by model number alone.
