Features
High-Speed Rigid Tapping: Synchronized servo spindle reversal with precise depth control prevents thread stripping.
Heavy-Duty Ribbed Cast Iron Bed: Stress-relieved Meehanite casting absorbs cutting harmonics and guarantees rigidity.
Fast Rapid Axis Traverse: Axis rapid speeds (30–48 m/min) dramatically reduce non-cutting cycle times.
Precision Servo Drive System: Closed-loop servo motors on all axes maintain ±0.02mm repeatable accuracy.

Industrial-Grade High-Precision CNC Drilling & Tapping Machine
The DUOMI CNC drilling and tapping machine (Model DNC-4030DT) is an engineered solution built for high-throughput precision machining across aluminium profiles, steel tubes, copper, and stainless steel components. Featuring a long-bed 4000mm X-axis stroke and dual servo-driven spindles, this heavy-duty CNC drill and tap center provides exceptional dynamic stability, thermal friction capability, and micro-meter precision for demanding industrial production environments.
Core Engineering Highlights & Technical Advantages
- Dual Servo-Driven Spindle Architecture: Dual high-speed spindles operating up to 24,000 RPM support simultaneous or independent drilling operations, dramatically reducing cycle times while preserving dimensional repeatability.
- Precision-Relieved Structural Frame: Fabricated from heavy-duty, stress-relieved cast frame components to dampen operational vibration during high-speed feed rates up to 60 m/min on the X-axis.
- Premium Motion Control Components: Integrates authentic HIWIN linear guideways and precision ball screws, delivering a repeated positioning accuracy of ±0.02mm and overall machine accuracy controlled within 0.02 mm.
- API Laser Interferometer Calibration (USA): Every machine unit undergoes strict metrological verification using an American API laser interferometer prior to dispatch, guaranteeing compliance with ISO/CE accuracy standards.
- Flexible 3-Axis CNC Control: Supports 3D CAD file import, computer-aided programming, and manual programming via intuitive hand pulse control (MPG) for seamless workflow setup.
Advanced Machining Capability: Thermal Friction & Conventional Operations
In addition to standard drilling (1–12 mm diameter) and tapping (M2–M12), the DNC-4030DT supports thermal friction drilling (flow drilling). This process utilizes frictional heat to form extruded bushings in thin-walled steel profiles, eliminating the need for riveted nuts or threaded inserts in sheet metal and tubular assemblies.
Applications & Multi-Station Processing
Designed for flexibility in metal fabrication workshops and high-volume industrial lines: - Long Profile Machining: Uniformly processes single long structural profiles from 1 to 4 meters in length. - Multi-Station Continuous Processing: Allows loading multiple smaller workpieces across the 4000mm x 280mm table surface for continuous, non-stop machining cycles.
