Features
4-in-1 Process Integration: Combines thermal friction drilling, roll form tapping, chamfering, and milling in a single automated setup—eliminating manual transfer bottlenecks and reducing total cycle time by up to 65%.
Chipless Bush-Forming (Zero Rivet Nuts): Displaces parent metal at 600°C to create an extruded integral bushing, tripling thread engagement depth without loose rivet nuts, welded studs, or chip debris inside sealed hollow profiles.
High-Speed 24,000 RPM Spindle & 60 m/min Rapids: High-torque BT30 direct-drive spindle (5.5–7.5 kW) delivers powerful downward thrust and rapid thermal build-up, supported by 60 m/min rapid traverse for maximum throughput.
10-Tool Spindle-Following Servo ATC: Direct-connect servo tool magazine travels synchronously with the spindle carriage, executing ultra-fast tool changes in under 3 seconds to keep production running continuously.
3000mm Extra-Long Machining Stroke: Massive 3000 × 280 mm worktable with quick-clamping pneumatic rail fixtures accommodates long structural steel beams, tubes, and frames, or supports dual-station pendulum batch loading.
Heavy-Duty Anti-Vibration Frame (±0.02mm Precision): Reinforced 2,100 kg stress-relieved machine bed absorbs severe friction-drilling thrust loads, maintaining ±0.02 mm repeat positioning accuracy and cutting defect rates to 0.2%.

Overview: High-Efficiency Thermal Friction Drilling Solution
The DUOMI CNC Flow Drill CNC Machine (Model DHM-3030N10) revolutionizes metal hole processing by combining thermal friction drilling (flow drilling), thread tapping, chamfering, and milling into a single automated station. Designed specifically for structural steel, hollow profiles, and metal tubing, this machine generates frictional heat up to 600°C to displace metal and form an integral bushed sleeve—increasing thread engagement depth by up to 3x without requiring rivet nuts or welded inserts.
Built for high-volume B2B manufacturing, the DUOMI Flow Drill CNC Machine delivers exceptional accuracy with a repeated positioning tolerance of ±0.02 mm and rapid traverse speeds up to 60 m/min.
Key Benefits & Technical Advantages
1. Multi-Process Integration & Rapid Productivity
- Eliminate Bottlenecks: Replaces multiple discrete manual operations (drilling, tapping, deburring) with a single-setup CNC cycle.
- High-Speed Machining: Equipped with a 24,000 RPM spindle and up to 60 m/min X-axis rapid feed, cutting total cycle times by up to 65%.
- 10-Tool Automatic Tool Changer (ATC): Servo-driven direct-connect tool magazine ensures seamless tool transitions in under 3 seconds.
2. Complex & Irregular Workpiece Machining
- Multi-Axis Linkage: Supports up to multi-axis coordinate control to machine complex surface angles, inclined holes, and structural frames.
- Flexible Fixturing: Features pneumatic rail-type clamping fixtures tailored for structural steel beams, liquid-cooling plates, and mobility vehicle chassis.
3. Substantial Defect & Scrap Reduction
- 0.2% Scrap Rate: Automated CNC path control eliminates human operational variance. Case studies show a defect rate reduction from 8.0% down to 0.2% in automotive component production.
- Annual Savings: Substantial waste reduction saves large-scale facilities over $500,000 annually in raw material scrap and rework labor.
4. 24/7 Continuous Automation
- Unmanned Operation: Fully compatible with robotic arm loading/unloading systems for round-the-clock light-out production.
- Lower Operator Threshold: Intuitive CAD/CAM import software allows operators to run multiple CNC flow drilling centers simultaneously.
Industrial Applications
- Structural Steel & Construction: Heavy-duty hollow profile joining and threaded fastenings.
- Automotive & EV Chassis: Engine block oil passages, battery tray frames, and mobility vehicle structures.
- HVAC & Liquid Cooling: Liquid-cooling pipes, manifolds, and thin-walled heat exchangers.
- General Hardware: Steel pipe framing, industrial racking, and agricultural machinery components.
Quality Assurance & Industry Standards
- Manufactured in compliance with CE safety standards.
- Dynamic balance tested spindle ensuring low vibration and long tool life during extended 600°C thermal friction operations.
