High-Rigidity Structure:

• This machine adopts a high-rigidity moving column structure, capable of supporting workpieces up to 10,000 kgs. This design reduces the load on the machine and minimizes thermal deformation, ensuring permanent mechanical precision.
• The machine base is made of Meehanite cast iron, which has undergone stress-relief heat treatment. It features a high-rigidity, symmetrically balanced design. The worktable is also heat-treated and precision-ground, making it wear-resistant under heavy loads while maintaining a consistent flatness.
• The base design utilizes a moving column structure to ensure that the flatness of the workpiece on the worktable remains unaffected during displacement, thereby achieving the highest possible working accuracy. The robust base design ensures that the machine remains free from deformation, even under prolonged heavy load.

Wide Linear Guideway Span and Precision Ball Screw:

• The X and Y axis utilize low-friction linear guides, ensuring machine precision and smooth operation even during displacement. The wide linear rails and broad span guarantee that the machine maintains accurate positioning and processing feed data during prolonged lateral and longitudinal movements, especially during reaming and vector machining, thereby ensuring long-term precision (backlash value).
• The X-axis linear guide (Φ 45mm) is mounted on the machine's middle base, ensuring the flatness during installation and extending the lifespan of the linear guide, thereby maintaining machine accuracy.
• The Y-axis linear guide (Φ 45mm) is mounted on the machine's upper base, ensuring flatness and lightness (non-load-bearing) during installation, reducing the friction coefficient of the linear guide, and extending its lifespan, thereby permanently ensuring machine precision.
• The X-axis (Φ 50mm) and Y-axis (Φ 50mm) are equipped with precision-grade ball screws paired with low-friction linear guides to ensure long-term machine precision.

Precision Spindle:

• The spindle is designed as an integrated cast structure to ensure stability while machining with large electrodes. It also features alloy steel guides (Φ 30mm) combined with roller bearings, which have a low friction coefficient, ensuring precise spindle feed accuracy.
• The spindle tower is equipped with a 400W servo motor, making the spindle operation lighter (without the need for counterweights) while ensuring displacement accuracy during operation and extending the lifespan of the ball screw (Φ 25mm).

C-Axis Features and Applications:

• The C-axis offers high-precision positioning capabilities, enabling accurate positioning and rotation of parts during the machining process. This ensures more precise machining and improved results, particularly when processing parts that require rotational machining.
• The C-axis can perform indexing machining, allowing fixed angle machining. This is particularly useful for parts that require periodic or repetitive machining, improving consistency and efficiency.
• For parts with complex thread structures, the C-axis can be used to machine threads. These thread structures may have special shapes that require machining at various angles, and the rotational capability of the C-axis allows for precise thread machining.

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.
