Executive Overview
The DUOMI DHM-1003DT(R1) is an advanced industrial CNC thermal drilling and tapping system designed to streamline pipe and profile processing. By integrating thermal friction drilling (flow drilling), chamfering, and thread tapping into a single setup, this solution eliminates multi-machine transfers, drastically lowers labor overhead, and increases throughput for automotive, HVAC, and structural steel manufacturing.
Key Benefits & Operational ROI
- Multi-Process Integration: Perform thermal friction drilling, high-speed tapping, chamfering, and light milling in one continuous CNC cycle, reducing cycle times by up to 65%.
- Drastic Defect Reduction: Lower component rejection rates down to 0.2% with automated multi-axis positioning and rigid workpiece clamping, minimizing scrap and material rework.
- High-Speed Axis Dynamics: Fast X-axis rapid traverse rates of 30–60 m/min and Z-axis speeds up to 25 m/min ensure rapid indexing across long workpiece layouts.
- Flexible 360° Rotary Axis: Equipped with a servo-driven A-axis and high-precision harmonic reducer to drill and tap square, round, or custom extruded profiles at any angle.
- Unmanned Automation Support: Seamlessly connects with robotic arms, automated loading/unloading systems, and external signals for continuous 24/7 industrial production.
Technical Advantages & Engineering Precision
Our specialized CNC thermal drilling platform leverages high spindle speeds (up to 6,000 RPM) to generate frictional heat, creating a reinforced collared bushing out of parent pipe material. This eliminates the need for weld nuts or press inserts while providing maximum thread engagement in thin-walled steel tubes.
