Industrial Overview
The DNC-1650D Small CNC Gantry Drilling Machine by DUOMI CNC is engineered to solve core B2B metalworking bottlenecks: labor dependency, long setup times, and high defect rates. Designed with a robust gantry structure, it integrates multi-process operations—drilling, tapping, chamfering, and milling—into a single setup. Built under stringent ISO 9001 and CE standards, the DNC-1650D provides exceptional structural rigidity and positioning accuracy for precision components across automotive, mold, hardware, and electronics manufacturing.
Key Advantages & Performance Metrics
- Multi-Process Integration: Eliminates separate drilling and tapping station transfers, significantly reducing cycle times and handling errors.
- Superior Precision: Features imported linear guides and high-precision ball screws delivering repeated positioning accuracy of ±0.02mm.
- High-Speed Axis Dynamics: Fast X-axis moving speeds of 30m/min to 60m/min combined with Y/Z axis speeds of 25m/min substantially cut non-cutting transition times.
- Defect Reduction & ROI: Case studies in automotive engine cylinder head manufacturing demonstrate a defect rate reduction from 8% down to 0.2%, yielding annual material cost savings exceeding $500,000.
- Flexible CAD/CAM Automation: Features direct CAD drawing file auto-import, computer programming, and support for automated loading/unloading robotic integrations for 24/7 lights-out operation.
Industrial Applications & Material Capability
The DNC-1650D small CNC gantry drilling machine processes a wide spectrum of industrial materials including ferrous and non-ferrous metals: - Supported Materials: Iron, Steel, Aluminum, Copper, Brass, Zinc, Platinum, and alloy plates/castings. - Machining Range: Drilling hole diameters from 1mm to 16mm, rigid tapping from M2 to M16, and chamfering up to 20mm. - Target Industries: Automotive parts, mold plates, heat exchangers, structural sheet metal, aerospace brackets, and general precision engineering.
