Press Brake

In CNC press brake operation, setting up dies on the ESA S875 controller is a pivotal step for achieving precise bending results and ensuring safe, collision-free production. If you’re seeking the correct procedures for ESA S875 die setup and proper methods to select, input and configure dies on the controller, this guide will provide clear and actionable answers. This article breaks down the full ESA S875 die setup process into practical, step-by-step instructions, helping you understand how die selection, drawing and data management impact bending accuracy and machine performance. Whether you’re new to the ESA S875 controller or looking to optimize your existing setup workflow, this guide will enable you to perform die setup correctly and boost the overall operational efficiency of your press brake.

Accessing the Die List on the ESA S875 Controller

Step 1: Displaying the Die List on the ESA S875

To start the ESA S875 die setup process, you first need to access the tool list on the controller interface.

Press the corresponding key to display either the punch list or the die list.

If the punch list appears on the screen, press the same key again to switch to the die list.

Once the die list is displayed, the screen is divided into three functional sections:

• Left window: Displays the full list of available dies

• Center window: Shows detailed dimensional data for the selected die

• Right window: Provides a graphical preview of the selected die

This interface layout allows operators to quickly identify the required die, which is particularly helpful when managing a large inventory of tools.

Step 2: Utilizing the Preview and Selection Functions

For quicker die identification during ESA S875 setup, you can enable the preview function to show a visual graphic of the selected die.

If the preview function is not needed, it can be disabled via the system menu by selecting the [Preview] option and toggling it off; the same operation will re-enable it when required.

To improve navigation efficiency on the interface:

• Press [List] to return the cursor to the die list

• Press [Selection] to manually enter a die’s name and locate a specific tool quickly

Direct scrolling on the touch panel is also supported, making it easier to browse through a large number of dies.

Managing Die Data on the ESA S875

Step 3: Copying, Renaming and Deleting Dies

Efficient die data management is a key aspect of long-term, effective use of the ESA S875 controller.

The system offers the following core management functions for dies:

• Copy a die: Create a new die based on the dimensions of an existing one, ideal for bending applications with similar requirements

• Rename a die: Establish clear, standardized naming conventions for dies for easy identification

• Delete unused dies: Keep the die database uncluttered and reduce the risk of selection errors

These functions help maintain an organized tool library, an essential practice in high-mix production environments or facilities with multiple work shifts.

Inputting a New Die into the ESA S875

Step 4: Selecting Between Drawn Dies and Preset Dies

When inputting a new die into the ESA S875 system, two setup methods are available:

• Preset dies: Predefined die types with fixed, adjustable parameters

• Fully drawn dies: Custom dies created from scratch with unique dimensions and shapes

Preset dies are recommended when the actual tooling closely matches one of the system’s predefined die types, as this can significantly cut down setup time. Fully drawn dies are necessary in the following scenarios:

• The die does not conform to any of the preset categories

• The die features multiple cavities

• The die has a special shape, square cavity or pressing cavity

Accurate die input is critical: the die drawing is used for the system’s collision detection, while bending depth calculations depend entirely on the dimensional data entered into the controller.

Step 5: Creating a Fully Drawn Die

For non-standard tooling, the ESA S875 allows for full custom die drawing via the [New Drawing] function.

After entering the die’s height and width parameters, the system will open the drawing interface, which consists of two main parts:

• A main drawing window on the left for visual die design

• Parameter input windows on the right for entering polar, Cartesian, V-cavity and square cavity dimensions

Dies must be drawn in a clockwise direction, with the stop position positioned on the right-hand side. This ensures the CNC system interprets the die’s design correctly.

Step 6: Modifying and Saving Preset Dies

Preset dies are displayed as pre-drawn shapes with adjustable parameters. As you scroll through the data fields and modify values, the corresponding dimension on the die drawing is highlighted in real time, making parameter adjustments intuitive and precise.

After modifying the required parameters, confirm the changes by pressing [ENTER]—the system will automatically update the die drawing to reflect the new values.

Once the preset die setup is complete, save the die by entering a unique name and pressing [OK]. Saved dies can be retrieved and reused in future bending programs, streamlining subsequent setup processes.

Best Practices for ESA S875 Die Setup

Proper die setup on the ESA S875 controller not only improves bending accuracy but also reduces the risk of tool collisions and enhances production consistency. For optimal results, always adhere to the following best practices:

• Ensure the entered die dimensions match the actual physical tooling exactly

• Follow the correct orientation rules when drawing custom dies

• Remove unused or outdated die data from the system regularly

Consistent and accurate die management ensures the press brake operates safely and efficiently across a wide range of bending applications.

Frequently Asked Questions (FAQ)

When should I use preset dies instead of fully drawn dies on the ESA S875?

Use preset dies when the actual tooling closely matches one of the predefined die types in the ESA S875 system. Preset dies offer faster setup and simpler parameter modification. Fully drawn dies are the better choice when the die has multiple cavities, a special shape or does not fit any of the system’s preset categories.

Can I copy an existing die during ESA S875 die setup?

Yes. The ESA S875 controller allows you to copy an existing die and save it under a new name. This function is extremely useful for creating similar dies with minor dimensional adjustments, as it reduces setup time and maintains consistency in tooling data across your production processes.

What are the common mistakes to avoid during ESA S875 die setup?

The most common mistakes include entering incorrect die dimensions, drawing dies in the wrong orientation and using outdated or inaccurate die data from the system. To avoid these issues, always verify the actual measurements of the die before inputting data, follow the system’s specified drawing direction for custom dies and perform regular maintenance on the ESA S875’s die database.

Conclusion

Proper ESA S875 die setup is fundamental to achieving precise bending results, reliable collision detection and stable press brake performance. By following the standard procedures—accessing the die list, using the preview and selection functions, managing die data effectively, inputting new dies and selecting the appropriate setup method (fully drawn or preset)—operators can configure the ESA S875 controller efficiently and minimize setup errors. Accurate die dimensional data and adherence to correct drawing conventions directly translate to improved bending precision and safer machine operation.

For the best production outcomes, we recommend keeping the die library well-organized, verifying all die parameters before starting production and using preset dies whenever possible to save valuable setup time.
