In today's world of advanced manufacturing, precision is everything. Whether it's electronics, aerospace, automotive, or medical equipment, the ability to drill micro and small holes with flawless accuracy defines product quality. Traditional drilling systems can't meet such demanding standards — and that's where CNC drilling machines for micro and small holes come in.
DUOMI CNC Micro and Small Hole Drilling Machine DNC-430D
Among global manufacturers, DUOMI CNC has earned a reputation for engineering high-speed, high-precision CNC drilling machines that specialize in micro and small hole processing. These machines have redefined what's possible in fine metal machining.
What Are Micro and Small Hole Drilling Machines?
A micro hole drilling machine or small hole drilling machine is a type of CNC drilling equipment designed to process holes ranging from 0.03 mm to 3 mm in diameter — sizes that demand exceptional accuracy, stability, and tool control.
Unlike conventional drills that rely on high cutting force, CNC drilling machines for micro holes operate with controlled feed rates, optimized spindle speeds, and vibration suppression technology. This ensures that even in ultra-thin materials or tough alloys, the holes remain clean, round, and burr-free.

The Challenge of Drilling Micro and Small Holes
Drilling holes smaller than a millimeter is one of the most complex tasks in machining. The issues include:
Tool breakage due to high rotational stress
Heat accumulation leading to material distortion
Chip evacuation difficulties
Positional errors caused by vibration or tool deflection
That's why advanced CNC micro hole drilling machines like those developed by DUOMI CNC are essential. They solve these challenges through smart automation, dynamic stability control, and high-speed precision spindles.

Why Choose DUOMI CNC for Micro and Small Hole Drilling?
1. Precision-Driven Design
Every DUOMICNC small hole drilling machine is built with ultra-fine motion control and linear guide systems that achieve positioning accuracy within ±0.01 mm.
This ensures consistent performance even during mass production — a critical factor for manufacturers in industries like semiconductors, watchmaking, and aerospace where every micron counts.
2. Ultra-Fast Spindle Technology
The heart of a CNC drilling machine for micro holes is its spindle. DUOMI CNC machines feature high-speed spindles capable of reaching up to 60,000 RPM, allowing for smooth, stable drilling even at microscopic diameters.
This spindle precision guarantees excellent surface finish, minimal burr formation, and longer tool life.
3. Customization for Every Industry
DUOMI CNC doesn't believe in “one-size-fits-all.” Every micro hole CNC drilling machine is custom-built to match specific production requirements — from hole diameter and depth to material type and drilling speed.
Whether you're working on stainless steel, aluminum, copper, brass, titanium, or carbon fiber, DUOMICNC engineers fine-tune the machine's configuration for optimal results.
