Features
Unmatched Structural Rigidity:Built on a double-aged, heavy-duty cast iron bed with 45mm roller linear guides. Eliminates the spindle chatter that causes stainless steel tube deformation.
High-Torque BT40 Spindle:Delivers the aggressive downward thrust and rotational stability required to effortlessly thermal-drill work-hardening alloys like 304 SS.
5-in-1 Automated Process:Milling, thermal drilling, tapping, counterboring, and deburring—all executed in one seamless setup. Zero manual intervention required.
100% Leak-Proof & Burr-Free Guarantee:Automated back-chamfering ensures zero micro-burrs clog server cooling channels, while precision counterbore milling creates a flawless seat for O-ring fittings.
Lightning-Fast Tool Changes:Equipped with a 24-tool spindle-following arm-type ATC, executing tool changes in just 2 seconds to maximize production throughput.
High-Capacity Batch Processing:The massive 600mm wide T-slot worktable accommodates multiple long manifolds simultaneously, drastically reducing load/unload idle times.

Overview
The CNC Thermal Friction Drilling and Tapping Machine for Liquid-Cooling Stainless Steel Pipes (Model DHM-3060N24) engineered by DUOMI CNC provides automated, high-precision hole-making and threading for thermal management components. Utilizing high-speed rotational thermal friction, this machine liquefies localized metal to form drawn bushings, creating thread depths up to 3 times the wall thickness without chips, burrs, or material waste.
Designed specifically for data center liquid-cooling manifolds, server cooling modules, heat exchangers, and industrial refrigeration systems, the DHM-3060N24 combines drilling, tapping, and milling into a single continuous clamping cycle for maximum production throughput and zero-leak reliability.
Key Features & Production Capabilities
- Single-Clamping Process Integration: Complete thermal friction drilling, high-speed tapping, and face milling in one setup to ensure perfect hole coaxiality (±0.02mm/1000 mm parallelism).
- High-Power BT40 Direct-Drive Spindle: Powered by a 7.5 kW motor delivering up to 48 N·m torque and 8,000 RPM spindle speed for optimal friction heat generation.
- 24-Tool Automatic Tool Changer (ATC): Disc-type magazine with rapid tool change capabilities minimizes idle downtime during multi-size drilling and tapping operations.
- Precision Axis Control: Heavy-duty linear guideways with X-axis travel of 3000 mm, Y/Z-axis travel of 600 mm, and rapid feeds up to 60 m/min.
- Chip-Free Thread Extension: Thermal flow drilling forms clean bushings from the parent material, delivering high-strength M3 to M24 threads suitable for high-pressure fluid fittings.
- Automated Lubrication & Cooling: Programmed timed lubrication for ball screws and guideways paired with dedicated tool cooling systems for extended tool longevity.
