Key benefits

Dual Servo-Driven Spindle for High Efficiency
The machine is equipped with a dual servo-driven spindle system, enabling simultaneous or independent drilling operations. This significantly improves machining efficiency while maintaining exceptional accuracy and stability.

Advanced CNC Control System
Flexible Programming Options
The machine is equipped with an advanced 4-axis CNC control system, supporting both:
Computer-based programming.
Manual programming.
This flexibility allows operators of different skill levels to easily control the machine.

Stress-Relieved Heavy-Duty Machine Structure
The machine body is built with a rigid, stress-relieved structure, providing excellent vibration resistance and long-term dimensional stability. This ensures consistent machining accuracy even under continuous industrial operation.

Premium Linear Guides and Ball Screws
The machine adopts HIWIN (Taiwan) linear guides and ball screws, known for their high rigidity, smooth motion, and excellent durability. This guarantees long-term stability and high-precision performance.

Precision Rotary Axis Design
Equipped with a high-precision rotary axis, the machine enables accurate positioning and multi-angle drilling on round tubes, making it suitable for complex hole patterns and multi-sided processing.

Absolute Servo Motor Control System
All transmission axes are driven by absolute servo motors, ensuring precise positioning and repeatability. The machine achieves a positioning accuracy of within 0.02 mm, meeting high-end industrial standards.

Fully Automatic Oil Cooling and Lubrication System
An integrated automatic oil cooling and lubrication system is applied to both the spindle and linear guideways. This system reduces heat generation, minimizes wear, and ensures long-term stable operation without manual maintenance.

Precision Assurance with Laser Interferometer Calibration
Before delivery, each machine undergoes full inspection using an API laser interferometer (USA). The system performs precise measurement and compensation to ensure overall machine accuracy is controlled within 0.02 mm.

This guarantees that every unit meets strict international precision standards before reaching the customer.
