Features
Horizontal End-Face & Side Machining: Horizontal spindle layout eliminates awkward vertical fixturing for long shafts and bars.
Natural Gravity Chip Evacuation: Metal swarf and coolant drop freely away from the hole, preventing tool recutting and tap breakage.
Multi-Angle Side-Hole Drilling: Efficiently machines radial oil holes, locking pin bores, and side threads on cylindrical workpieces.
Ultra-Rigid Low Center of Gravity: Robust horizontal casting bed resists axial drilling thrust and maintains long-term alignment.
High-Efficiency Automatic Clamping: Hydraulic/pneumatic self-centering vices speed up repetitive parts changeover.

Executive Overview
The DUOMI DNC-3050N8 Metal CNC Side Hole Drilling Machine is an industrial-grade horizontal machining solution engineered for high-speed drilling, tapping, and chamfering on complex workpiece sides. Powered by a high-rigidity BT30 spindle capable of speeds up to 24,000 RPM and supported by an 8-station automatic tool changer (ATC), the DNC-3050N8 substantially reduces cycle times for medium to high-volume production.
Featuring an extended X 3000 mm × Y 100 mm × Z 100 mm machining envelope and absolute servo motor drives on all axes, this machine delivers consistent high-precision processing across ferrous and non-ferrous metals.
Core Engineering & Key Features
- BT30 High-Speed Spindle System: Delivers 5.5–7.5 kW power with speed ranges from 1,500 to 24,000 RPM, accommodating drilling diameters from 1 mm to 20 mm and tapping ranges from M2 to M20.
- Automatic 8-Tool Carousel: Features dynamic tool change routines that eliminate manual tool setups during multi-hole, multi-diameter machining operations.
- Precision Linear Motion: Utilizes premium HIWIN ball screws and linear guideways across all motion axes, driven by absolute servo systems reaching X-axis rapid traverse speeds of 30–60 m/min.
- API Laser Interferometer Verified: Every unit undergoes strict quality verification using US-imported API laser interferometers, guaranteeing overall machine accuracy within 0.02 mm and repeatability of ±0.02mm.
- Dual-Piston Pneumatic Clamping: Supports 2 to 10 automated workstations, enabling multi-station cycle machining to maximize throughput and minimize loading downtime.
- CAD/CAM Integrated CNC Controller: Supports direct CAD file imports for automatic program generation, eliminating complex G-code programming while offering storage for over 10,000 programs.
Industrial Applications & Materials
Designed for heavy-duty industrial environments, the DNC-3050N8 excel at processing structural profiles, side-hole plates, heat sinks, linear housings, and custom extrusions.
- Compatible Materials: Steel, Cast Iron, Aluminum Alloys, Copper, Brass, Zinc, and Platinum.
- Target Industries: Industrial Machinery, Automotive Components, Structural Engineering, Electronics Enclosures, and Aerospace Assemblies.
