When it comes to CNC press brake operation, ESA S875 Dies Setup is one of the most critical steps for achieving accurate bends and safe, collision-free production. If you are wondering what the correct steps for ESA S875 dies setup are and how to properly select, enter, and configure dies in the controller, this guide is designed to give you a clear answer. In this article, I explain the complete ESA S875 dies setup process in a practical, step-by-step way, helping you understand how die selection, drawing, and data management affect bending accuracy and machine performance. Whether you are new to the ESA S875 controller or looking to optimize your current setup, this overview will help you set up dies correctly and improve overall press brake efficiency.

How to Access the Dies List on ESA S875 Controller

Step 1: Displaying the Dies List in ESA S875

To begin the ESA S875 dies setup, you must first access the tools list on the controller interface.

If the punches list appears, press the same key again to switch to the dies list.

Once the dies list is displayed, the screen is divided into three functional areas:

• Left window: Displays the list of available dies
• Center window: Shows detailed data for the selected die
• Right window: Provides a visual preview of the selected die

This layout allows operators to quickly identify the correct die, especially when managing a large number of tools.

Step 2: Using Preview and Selection Functions

For faster identification during ESA S875 dies setup, the preview function can be enabled to display a graphical representation of the selected die.
If preview is not required, it can be disabled through the system menu by selecting the [Preview] option and toggling it off. Repeating the same operation will re-enable it.

To improve navigation efficiency:

• Use [List] to move the cursor back to the dies list
• Use [Selection] to manually enter the die name and quickly locate a specific tool

Scrolling can also be performed directly on the touch panel, which is especially useful when many dies are available.

Managing Dies Data in ESA S875

Step 3: Copying, Renaming, and Deleting Dies

Efficient die management is an important part of long-term ESA S875 controller usage.
The system allows users to:

• Copy a die to create a new tool based on existing dimensions, ideal for similar bending applications
• Rename a die to maintain clear and standardized tool naming
• Delete unused dies to keep the database clean and reduce selection errors

These functions help maintain an organized tool library, which is especially important in high-mix or multi-shift production environments.

How to Enter a New Die in ESA S875

Step 4: Choosing Between Drawn Dies and Preset Dies

When entering a new die, ESA S875 provides two setup methods:

• Preset dies with fixed, adjustable parameters
• Fully drawn dies created from scratch

Preset dies are recommended when the actual tooling closely matches one of the predefined die types, as this significantly reduces setup time. Fully drawn dies are required when:

• The die does not match preset categories
• Multiple cavities are used
• Special shapes, square cavities, or pressing cavities are involved

Accurate die entry is critical because the die drawing is used for collision detection, while bending depth calculations rely on the dimensional data.ng depth calculations rely on the dimensional data entered.

Step 5: Creating a Fully Drawn Die

For non-standard tooling, ESA S875 allows full die drawing through the [New Drawing] function.
After entering the die height and width, the system opens the drawing mask. The drawing interface includes:

• A main drawing window on the left
• Data input windows for polar, Cartesian, V-cavity, and square cavity parameters on the right

The die must be drawn in a clockwise direction, keeping in mind that the stop position is located on the right-hand side. This ensures correct interpretation by the CNC system.

Step 6: Modifying and Saving Preset Dies

Preset dies are displayed as pre-drawn shapes with adjustable parameters. When scrolling through data fields, the corresponding dimension is highlighted directly on the drawing, making adjustments intuitive and precise.

After modifying the required values and confirming with [ENTER], the system automatically updates the drawing.
Once the setup is complete, save the die by entering a unique name and confirming with [OK]. This allows the die to be reused in future bending programs.

Best Practices for ESA S875 Dies Setup

Proper dies setup on the ESA S875 controller improves bending accuracy, reduces tool collision risks, and enhances production consistency. For optimal results, always ensure that:

• Die dimensions match the actual tooling
• Drawn dies follow correct orientation rules
• Unused or outdated dies are removed from the system

Consistent and accurate die management allows press brake systems to operate safely and efficiently across a wide range of bending applications.

Frequently Asked Questions(FAQ)

Conclusion

Proper ESA S875 dies setup is essential for ensuring accurate bending results, reliable collision detection, and stable press brake performance. By following the correct steps—accessing the dies list, selecting and previewing tools, managing die data, entering new dies, and choosing between fully drawn or preset dies—operators can configure the ESA S875 controller efficiently and reduce setup errors. Accurate die dimensions and correct drawing conventions directly contribute to improved bending precision and safer machine operation.

To achieve the best results, it is recommended to keep the die library well organized, verify die parameters before production, and use preset dies whenever possible to save setup time.
