System Overview & Thermal Friction Drilling Technology
The DUOMI DHM-2040N10 Automatic Tool Change Flow Drilling CNC Machine combines thermal friction drilling (flow drilling), thread tapping, chamfering, and light milling into a single setup. By utilizing high rotational speeds (up to 24,000 RPM) and controlled axial pressure, the tungsten carbide flow drill generates localized frictional heat (600°C–800°C) to plasticize thin-walled metals, forming a solid bushing up to 3–5 times the original wall thickness. This eliminated the need for weld nuts, press inserts, or riveted fasteners while ensuring high thread pull-out strength.
Equipped with a 10-station servo-driven Automatic Tool Changer (ATC) mounted directly to the spindle assembly, the DHM-2040N10 reduces tool-to-tool change time to under 1.5 seconds, delivering continuous 24/7 industrial production capability.
Core Engineering Features & Performance Advantages
- High-Speed BT30 Spindle System: Choose between a high-speed direct-drive spindle (up to 24,000 RPM) for high-friction flow drilling or a heavy-duty mechanical spindle for larger tapping diameters (up to M16).
- Superior Repeatability & Rigidity: Built on a heavy cast iron base, the machine achieves ±0.02mm repeatability across X/Y/Z axes (X: 2000mm, Y: 400mm, Z: 200mm) with rapid movement speeds up to 60 m/min on the X-axis.
- Defect Rate Reduction to 0.2%: Industrial field data shows a defect rate drop from 8.0% to 0.2% compared to manual drilling and tapping setups, yielding annual scrap savings exceeding $50,000 per production line.
- Multi-Axis Linkage & CAD/CAM Integration: Supports G-code, direct CAD DXF file import, and flexible multi-axis positioning for machining complex profiles, round tubes, square tubing, and angled structural frames.
- Automated Load/Unload Compatibility: Seamlessly integrates with industrial robot arms and pneumatically clamped fixtures for automated unmanned cell operation.
