We Don't Try to Do Everything.
We Focus on One Thing: Drilling & Tapping.
Duomi is a CNC machine manufacturer based in Dongguan, Guangdong, China, specializing in drilling and tapping solutions for industrial production.
Drilling and tapping may look simple.
In real production, they are not.
Hole size, depth, position, material, thread quality, tool life, chip evacuation, coolant, fixtures, cycle time and operator handling can all affect the final cost of a part.
Maintaining tight diameter tolerances and depth consistency across thousands of parts.
Eliminating cumulative tolerance stack-up during complex multi-surface hole positioning.
High-torque rigid tapping and thermal flow forming with zero stripped threads.
Optimized high-speed spindle dynamics and micro-feed control down to Ø0.15mm.
Rapid, controlled chip evacuation preventing tool jamming and surface scratching.
Precise through-spindle cooling and MQL delivery directly to the cutting edge.
Rigid multi-station clamping allowing 360° rotary multi-face machining in 1 setup.
Compressing auxiliary tool changes and part flipping to shave off crucial seconds.
From Standard Machines to Engineered Solutions
Different workpieces require different approaches.
- Some applications need ultra-high-speed drilling.
- Some require multi-spindle simultaneous processing.
- Some combine drilling, tapping, and countersinking in a single cycle.
- Some require deep-hole or extra-long workpiece machining.
- And some cannot be solved effectively with a standard machine at all.
That's why Duomi develops both standard CNC drilling & tapping machines and application-specific solutions tailored around the customer's production process.
Your part defines the solution.
Our Goal Is Not to Sell You More Machine.
Our goal is to help you produce more efficiently.
When we evaluate an application, we look beyond machine specifications.
The true value of a CNC machine is not how much it costs to purchase.
It is what it changes in your production.
