Industrial Product Overview
The 12 Meters CNC Drilling Machine (Model DNC-1203 2DR) by DUOMI CNC is an industrial-grade, multi-axis machining system designed for high-speed, automated drilling, tapping, and hole perforation across extra-long structural metal profiles and heavy-walled tubes. Featuring an expansive 12,000 mm X-axis stroke and dual asynchronous spindles, this heavy-duty CNC pipe and profile drilling system delivers maximum throughput with exceptional accuracy for global fabricators.
Built to rigorous ISO 9001 quality management standards, the machine integrates precision linear guides, high-torque servo drives, and an extended rotary clamping unit capable of handling tube diameters from 80 mm to 160 mm. It provides an all-in-one solution that eliminates manual layout, template jigs, and multi-stage re-clamping.
Technical Features & Performance Capabilities
Extended 12-Meter Machining Envelope
- 12,000 mm X-Axis Travel: Single-pass machining capability for ultra-long architectural structural channels, automotive frames, and oilfield filter screen pipes.
- Rotary Axis (A-Axis 360°): Automated 360-degree rotation allows multi-sided drilling and circumferential hole indexing without manual workpiece re-clamping.
- Repeated Positioning Accuracy: High-precision ball screws and linear guides deliver ±0.02mm repeatability across the entire travel length.
Dual Asynchronous Independent Spindles
- Synchronized & Independent Operation: Twin spindles run independently on distinct program coordinates or in tandem to double production output.
- Multi-Size Tooling Capability: Run different drill bit diameters or carry out simultaneous drilling and tapping operations on opposite spindle heads.
- Zero Distortion Thermal Friction Drilling (Optional): Optimized spindle drive supports thermal friction drilling (flow drilling) for chip-free, extruding thread bushings on thick-walled carbon steel, stainless steel, and aluminum pipes up to 8 mm wall thickness.
Advanced CNC Controls & Automation Interface
- Flexible CNC Programming: Direct G-code execution, CAD/CAM file import, or intuitive touch-panel manual programming.
- Massive Storage Capacity: On-board memory stores up to 10,000 system programs for instant job recall and minimal changeover downtime.
- External Automation Signal Control: Seamless integration into automated conveyor lines, robotic loading units, and Industry 4.0 shop floor networks.
