Overview
The DUOMI CNC Drill & Tap Machine (Model DNC-640N6) with Auto Tool Changer is an all-in-one industrial metalworking solution engineered for high-throughput precision manufacturing. By integrating drilling, tapping, chamfering, and milling operations into a single clamping cycle, this machine eliminates frequent fixture re-adjustments and machine changeover delays.
Built for demanding international production environments, the DNC-640N6 drastically cuts cycle times and delivers extreme dimensional consistency across diverse alloys and complex geometries.
Key Features & Production Advantages
- Multi-Process Efficiency: Perform drilling (1–12mm), tapping (M2–M8), chamfering, and milling in one single setup.
- Rapid Automatic Tool Changer (ATC): Features a 6-knife rotary tool magazine for seamless tool swaps and uninterrupted production workflows.
- High-Speed Machining Capability: Variable spindle speeds reaching 1,500 to 24,000 RPM combined with X-axis feed rates up to 60m/min minimize non-cutting cycle times.
- Precision Engineering: Achieves tight repeated positioning accuracy of ±0.02mm, ensuring near-zero scrap rates across continuous batch manufacturing.
- Flexible CAD/CAM Integration: Supports direct CAD file imports, computerized program transfers, and standard manual programming storing up to 10,000 operational programs.
- Robotic Automation Ready: Fully compatible with external signal controls for automated robotic loading/unloading, enabling 24/7 unmanned operations.
Proven ROI & Operational Precision
In high-volume manufacturing, precision directly dictates profitability. In automotive engine cylinder head production involving complex internal oil passage holes, conventional multi-machine processes frequently experience failure rates around 8%.
Upgrading to the DUOMI CNC Drill & Tap Machine reduced part defect rates to under 0.2%, yielding annual raw material savings exceeding $500,000 USD for high-volume production facilities.
Multi-Industry Applications
- 3C Electronics & Heat Sinks: High-speed micro-drilling and tapping for aluminum enclosures and precision radiator modules.
- Automotive Components: Engine cylinder heads, valve bodies, and die-cast aluminum housings.
- Hardware & Fasteners: Copper, brass, steel, and zinc architectural or industrial components.
- Tubing & Extrusions: Precision hole-pattern processing for aluminum structural profiles and steel tubing.
