    DUOMI'S CNC DEEP HOLE DRILLING MACHINE


    Intelligent CNC Control, Easy Operation

    The machine is powered by a Taiwan SYNTEC CNC control system, allowing one-touch machining and intuitive operation. Even complex deep hole drilling CNC processes can be executed smoothly with minimal training, reducing setup time and operator dependency.


    Rigid Structure for Deep Drilling Applications

    An extra-wide base combined with a herringbone-style column forms a one-piece cast structure. This design significantly improves rigidity and vibration resistance, which is critical for deep drilling machine operations involving small diameters and long depths.


    High-Precision Spindle Performance

    The spindle adopts a Taiwan DANNCHUAN servo mechanical spindle, delivering stable torque and precise rotation. Drilling accuracy remains consistent, with surface finish reaching Ra 0.8 or better, even in demanding small diameter deep hole drilling applications.


    Full Servo Drive for Stable Motion

    All axes are driven by servo motors, ensuring precise positioning, smooth movement, and long-term operational stability. This configuration is especially important for cnc deep hole drilling machine processes where alignment and repeatability directly affect hole quality.


    Premium Linear Motion Components

    Each axis uses Taiwan-imported HIWIN / TBI high-precision linear guideways and ball screws. These components offer high rigidity, low noise, and reliable accuracy, supporting both deep hole drilling and boring machine applications.


    Clean and Safe Working Environment

    An integrated oil mist collection system helps maintain a clean workshop environment while improving operator safety. Fully enclosed machine guarding further protects both personnel and equipment during continuous operation.


    Built-In Protection for Daily Production

    The machine is equipped with X / Y / Z axis travel limit protection, effectively preventing damage caused by incorrect operation. This feature adds another layer of security in real production environments.
