In the evolving world of metalworking, efficiency, precision, and automation are no longer luxuries—they're necessities. One of the most revolutionary advancements in this field is the CNC flow drilling and tapping machine, a technology that combines strength, heat, and accuracy to create holes and threads in metals like steel, stainless steel, brass, aluminum, and copper without using traditional cutting methods.

DUOMI CNC Flow Drilling and Tapping Machines
Among the top innovators in this space, DUOMI CNC has become a trusted global manufacturer of flow drilling machines and CNC flow drilling and tapping machines that are transforming how manufacturers handle metal processing tasks.
What Is Flow Drilling?
Flow drilling—sometimes called thermal drilling or friction drilling—is a process that uses frictional heat and axial force to form a hole in metal, rather than cutting or removing material.
A flow drill rotates at high speed, generating enough heat to soften the metal surface and push material aside, forming a smooth, durable bushing around the hole. This bushing becomes a reinforced area for threading, allowing stronger connections for bolts or screws.
Unlike traditional drilling, which removes material, flow drilling redistributes it—resulting in zero chip waste and a stronger joint. It's a sustainable, high-efficiency process used in industries like automotive, aerospace, HVAC, furniture manufacturing, and construction.
Why CNC Flow Drilling and Tapping Machines Are Changing the Game
The integration of CNC (Computer Numerical Control) technology into flow drilling and tapping machines has taken this method to an entirely new level.
1. Precision Meets Automation
CNC control ensures that every movement—from rotation speed to drilling depth—is precisely programmed. This automation eliminates human error, ensuring consistent hole quality across thousands of parts.
With DUOMI CNC flow drilling and tapping machines, operators can easily set parameters on the touch screen, monitor performance, and produce accurate, repeatable results without needing advanced programming experience.
2. Drilling and Tapping in One Setup
One of the biggest advantages of a CNC flow drilling and tapping machine is its ability to complete both processes—hole forming and thread tapping—in a single automated cycle.
This drastically reduces setup time and increases productivity, allowing factories to produce more parts in less time while maintaining impeccable accuracy.
3. Enhanced Structural Strength
Flow drilling creates a bushing that is three to four times the material's thickness. When threads are tapped into this bushing, the connection becomes stronger and more durable than those made using traditional drilling methods.
This makes flow drilling machines ideal for components that must withstand vibration, torque, or pressure—like automotive frames, hydraulic systems, or machinery housings.
