Industrial Precision Drilling for Extended Metal Profiles
The DUOMI DNC-3030HD CNC Drilling Machine for Long Metal Profiles is engineered for high-throughput, sub-millimeter micro-hole machining across extended workpieces up to 3,000 mm in length. Engineered to solve traditional manufacturing bottlenecks, this machine integrates multi-process functionality—including micro-drilling, tapping, chamfering, and milling—into a single high-efficiency setup.
Equipped with a high-frequency water-cooled spindle capable of reaching 60,000 RPM and full servo drive control, the DNC-3030HD guarantees micro-level spindle runout and repeatable positioning accuracy within ±0.02mm. Whether processing structural steel, aluminum extrusions, copper plates, or specialty alloys, DUOMI CNC delivers uncompromising dimensional consistency.
Core Technical Advantages
- Extended Machining Envelope: Generous X/Y/Z stroke of 3000mm x 300mm x 200mm paired with a 3000mm x 280mm heavy-duty table for long structural components.
- Micro-Hole Capability: Precision micro-drilling from 0.05 mm to 3.0 mm diameter, ideal for heat exchangers, fluidic channels, and aerospace components.
- Ultra-Fast Axis Dynamics: Rapid movement speed up to 60 m/min on the X-axis and 25 m/min on Y/Z axes to eliminate non-cutting cycle time.
- Thermal Stability: Spindle water-cooling cycle controls thermal expansion, maintaining constant temperature and operational stability during continuous 24/7 manufacturing runs.
- Automation Ready: Optional Automatic Tool Changer (ATC), robot loading/unloading interface, and pneumatic clamping reduce labor requirements and lower defect rates to 0.2%.
Industrial Applications & Material Compatibility
Designed for rigorous industrial demands, the DNC-3030HD is widely implemented across automotive, aerospace, structural engineering, electronics, and medical equipment manufacturing.
- Compatible Materials: Structural Iron, Copper, Aluminum Alloys, Brass, Stainless Steel, Zinc, Platinum, Graphene Plates, and Ceramic Substrates.
- Typical Workpieces: Extended pipes, structural metal beams, heat sink plates, engine oil passage heads, aerospace fasteners, and long architectural profiles.
