To ensure more stable positioning accuracy during machining, the EB433 is equipped with 1μm optical scales on all three axis, ensuring precision throughout the machining process. For added ease of operation and to enhance machining accuracy, the EB433's screen is positioned on the right side of the Z-axis and is equipped with a swivel arm, allowing operators to more conveniently align molds and adjust parameters based on machining conditions.
Additionally, the EB433 can be optionally equipped with a C-axis and ATC (Automatic Tool Changer) to achieve high-efficiency automated machining.
In summary, the EB433 is a powerful, highly precise, and user-friendly CNC EDM machine, ideal for various precision machining needs, making it an excellent choice in industrial manufacturing.

Machine Introduction

The EB433 is a high-precision CNC EDM machine that utilizes precision-grade ball screws and linear guides in its components, ensuring accuracy in both orbit and vector machining. It is also equipped with Delta's AC servo motors, providing reliable power support.
The machine's specifications include an XYZ axis travel of 400 / 300 / 300mm and a table size of 600 x 350mm, making it suitable for processing medium to small-sized workpieces.

Here are three application examples of the EB433:

• Bottle Caps: The internal spiral structure requires CNC jogging functionality for machining, while the external anti-slip patterns also need EDM processing. The EB433, with its high-precision machining capabilities, can effectively produce complex internal and external structures, ensuring the quality and functionality of the bottle caps.
• Screw Thread Repair: When the thread holes in a mold are damaged or worn, they need to be repaired. The EB433 can perform precise thread repairs using its XY, YZ, and XZ jogging functions, allowing accurate repairs regardless of whether the thread hole is located on the top or the side.
• Seatbelt Components: The internal parts of a seatbelt assembly often have complex shapes and structures that require precision machining. The EB433's side-placement feature allows operators to easily perform machining, ensuring the accuracy and integrity of the internal components.

High-Rigidity Structure:

• The machine body structure utilizes CAE (Computer-Aided Engineering) to simulate structural analysis of each axis during actual operation. Therefore, we have adopted a high-rigidity T-shaped body structure to reduce load and thermal deformation issues, ensuring long-term precision of the machine.
• Made from Meehanite cast iron and stress-relieved through heat treatment, the structure features a high-rigidity, symmetrically balanced design, which helps reduce load and thermal deformation.

XYZ-Axis Travel Structure:

• The X, Y, and Z axis use low-friction linear guides and ball screws, ensuring precision even under heavy loads while allowing for agile operation during machining. This design guarantees both accuracy and flexibility throughout the machining process. Additionally, the wide span of the linear guides ensures that the parallelism of the worktable remains unaffected during movement in any direction under load, thereby ensuring machining quality and stability.
• A belt-driven servo system is employed to reduce the size of the machine. By utilizing gear ratio, even a low-wattage servo motor can drive the entire machine, meeting energy-saving requirements. This design not only enhances the machine's operational efficiency but also reduces energy consumption, aligning with environmental and energy-saving goals.

Features and Applications of the C-axis:

• The C-axis features high-precision positioning capabilities, enabling accurate positioning and rotation of parts during machining. This allows for more precise machining and better results, especially when processing parts that require rotational machining.
• The C-axis can achieve indexed machining, allowing parts to be machined at fixed angles. This function is particularly useful for parts that require periodic or repetitive machining, significantly improving consistency and efficiency.
• For parts with complex thread structures, the C-axis can perform thread and complex shape machining. If the part has special-shaped threads that need to be machined at different angles, the rotational capability of the C-axis can precisely achieve the required shapes.

Automatic Tool Changer (ATC) and the Advantages of Automation:

• Allows quick and precise tool changes, reduces tool change time and thereby increasing machining efficiency.
• Ensure that it is precise in every tool change, avoiding errors caused by human factors, which in turn improves machining accuracy.
• Can automatically complete tool changes during the machining process, reducing downtime and increasing machine uptime.
• Minimizes the need for manual intervention, reducing labor requirements while also lowering the risk of errors and accidents caused by human operation.

Controller Performance and Features

● Automatic Indexing: The system allows users to directly select material type and area, input machining depth and starting height, and then automatically search for the optimal conditions to generate the machining program. Users can also edit and save the generated program, which can be reloaded for future use without altering the original database content.
● High-Efficiency Discharge Module: The discharge circuit uses MOSFET transistors and a fast discharge device (POWER SINK) to enhance machining efficiency and reduce electrode wear. The machining circuit employs FPGA IC components for faster monitoring of discharge conditions (up to single discharge waveform monitoring), providing more effective prevention of carbon buildup (ARC). Users can set ARC voltage levels, ARC time, and ARC sensitivity to further improve machining efficiency. Additionally, it offers two-stage gap and two-stage off-time functions to assist users in automatically adjusting machining parameters when ARC occurs, leading to better machining efficiency. These features and designs aim to improve machining efficiency, reduce wear, and provide better operability and stability.
● Servo Control: The servo control system uses DSP digital processing, allowing for faster response times, with loop control occurring every 0.2ms, which is faster than the typical 1ms or more response time of PC-based controllers. This characteristic enhances spindle stability during machining, ensuring smoother machine operation.

Additionally, the CNC EDM machine offers a multi-stage debris removal mode, suitable for deep hole machining and thin sheet processing, providing more flexible machining options.
Moreover, the servo protection function is an important feature that prevents electrode damage caused by improper user operation, such as mold crushing. This protection function ensures the safety and longevity of the electrode during the machining process.
These combined features make the CNC EDM machine's servo control more flexible, stable, and safe, capable of meeting various machining demands while ensuring high-quality machining results.
