Precision is never an accident. At DUOMI CNC, we design and manufacture CNC deep hole drilling machines for manufacturers who work with demanding tolerances, long drilling depths, and small diameters—every day, at scale.

This is not a general-purpose solution. It is a purpose-built cnc deep hole drilling machine developed for stable, repeatable, and efficient deep drilling in metal components where accuracy and surface finish truly matter.

CNC Deep Hole Drilling Machine by DUOMI CNC

Built for Deep, Small-Diameter Accuracy

Deep hole drilling is challenging by nature. As depth increases and diameter decreases, stability, chip evacuation, and tool life become critical. DUOMI CNC addresses these challenges at the engineering level.

Our machines are optimized for:

• Small diameter deep hole drilling with consistent straightness

• High aspect-ratio holes with controlled runout

• Continuous operation without vibration or thermal drift

Whether you refer to it as a deep hole drill machine, a deep drilling machine, or deep hole drilling CNC, the goal remains the same: holes that meet specification, batch after batch.

Why Manufacturers Choose DUOMI CNC

Stable Structure, Predictable Results
Machine rigidity is the foundation of deep hole drilling. DUOMI CNC machines use reinforced frames and precision-guided motion systems to maintain alignment even at extended drilling depths.

Designed for Real Production
This is not lab equipment. Our cnc deep hole drilling machine is designed for factory floors, multi-shift operation, and real workloads—where downtime costs money.

Optimized for Chip Control
Efficient chip evacuation is essential in deep hole drilling and boring machine applications. Our systems are engineered to support stable coolant flow and smooth chip removal, reducing tool wear and protecting surface quality.

Deep Hole Drilling CNC for Multiple Industries

DUOMI CNC machines are widely used in industries where deep, accurate holes are non-negotiable:

• Automotive components and shafts

• Aerospace structural parts

• Hydraulic and pneumatic components

• Medical and precision mechanical parts

• Energy and industrial equipment

From straight deep holes to combined deep hole drilling and boring machine operations, our solutions adapt to your process—not the other way around.

Precision Where It Matters Most

Manufacturers working with small diameter deep hole drilling know that tolerances tighten as depth increases. DUOMI CNC focuses on control, not marketing buzzwords.

What you can expect:

• Consistent hole geometry

• Reliable depth accuracy

• Improved tool life

• Reduced scrap rate

This is deep hole drilling CNC equipment built by people who understand machining realities.

A Manufacturer, Not a Trading Company

DUOMI CNC is a real manufacturer with in-house design, assembly, and testing. Every deep hole drill machine is inspected and run before delivery. We believe trust is built through performance, not promises.

We work closely with customers to match spindle configurations, stroke length, and tooling systems to actual production needs—whether standard or customized.
