Features
Horizontal End-Face & Side Machining: Horizontal spindle layout eliminates awkward vertical fixturing for long shafts and bars.
Natural Gravity Chip Evacuation: Metal swarf and coolant drop freely away from the hole, preventing tool recutting and tap breakage.
Multi-Angle Side-Hole Drilling: Efficiently machines radial oil holes, locking pin bores, and side threads on cylindrical workpieces.
Ultra-Rigid Low Center of Gravity: Robust horizontal casting bed resists axial drilling thrust and maintains long-term alignment.
High-Efficiency Automatic Clamping: Hydraulic/pneumatic self-centering vices speed up repetitive parts changeover.

Overview
As a premier Horizontal CNC Drilling Manufacturer, DUOMI CNC delivers advanced industrial machining solutions engineered for high-speed, heavy-duty metal fabrication. The DNC-3050N8 Horizontal CNC Drilling and Tapping Machine integrates high-precision drilling, rigid tapping, and edge chamfering into a unified automated platform. Featuring a 3000mm X-axis stroke, high-speed BT30 spindle, and automatic 8-tool changer, this system delivers optimal throughput and accuracy for profile machining, tube processing, and multi-station production.
Technical Superiority & Performance Engineering
Our horizontal CNC drilling machinery is built for high-rigidity and vibration-free operation under multi-shift production conditions:
- BT30 High-Speed Spindle Unit: Variable speed control ranging from 1,500 to 24,000 RPM, delivering 5.5kW to 7.5kW of driving power to effortlessly handle drilling diameters from 1mm to 20mm and tapping sizes from M2 to M20.
- Linear Motion & Servo Drivetrain: Driven by high-torque absolute servo motors and equipped with precision HIWIN linear guideways and ground ball screws. Achieves rapid traverse rates of up to 60 m/min along the X-axis and 25 m/min along Y/Z axes.
- Precision Laser Alignment: Every machine is verified using imported US API laser interferometers, ensuring absolute positioning accuracy with compensated machine tolerances held within 0.02 mm and repeatable accuracy of ±0.02mm.
Key Operational Features
Intelligent CAD/CAM CNC Controller
The integrated DUOMI CNC control unit features an intuitive color LCD display supporting English and Chinese interfaces. Key software highlights include direct CAD drawing import with automatic G-code generation—eliminating the necessity for expert programmer intervention—alongside visual dynamic zoom path previewing and storage capability for over 10,000 machining programs.
8-Station Automatic Tool Changer (ATC)
An integrated 8-tool holder magazine arranged on the left and right positions enables seamless tool changes during complex multi-specification aperture processing. This reduces non-cutting idle time and boosts productivity by up to 40% over manual tool change systems.
Dual-Piston Pneumatic Workholding System
Equipped with dual output sliding cylinder clamps designed to secure workpiece surfaces firmly, eliminating chatter during dynamic side drilling operations. Supports 2 to 10 automated workstations for continuous shuttle machining, dramatically reducing operator loading and unloading cycles.
Automated Lubrication & Chip Filtration
Equipped with a metered, timed automatic drivetrain lubrication system for all linear motion components. The secondary chip filtration and coolant recirculating system continuously evacuates metal debris, protecting tooling investment and maintaining clean shopfloor operations.
Industrial Applications
Designed to handle various non-ferrous and ferrous metal substrates, including carbon steel, stainless steel, aluminum alloy extrusion, copper, brass, iron, zinc, and platinum components. Common production line integrations include: * Structural aluminum frame profile side-hole drilling * Flange, heat exchanger, and manifold pipe tapping * High-volume automotive, aerospace, and electrical housing component machining
