Executive Overview: Industrial Horizontal CNC Drilling & Tapping Automation
Modern metalworking and industrial parts manufacturing require high accuracy, rigidity, and rapid tool cycle times. The DUOMI CNC Horizontal Machine (Model DNC-2020N4) integrates automatic 3-axis drilling, precision tapping, and chamfering into a single robust horizontal machining station. By eliminating redundant workpiece setup steps and manual tool changing, this machine boosts production throughput while maintaining exact repeatability.
Designed for structural tubing, metal plates, profiles, and complex side-drilling workpieces, our horizontal CNC machining setup features a BT30 high-speed spindle (1000–6000 RPM), 5.5 KW spindle motor power, and a 4-tool automatic tool changer (ATC) to satisfy versatile B2B manufacturing demands.
Key Technical Advantages & Business ROI
- High-Precision Multi-Process Execution: Performs side drilling (1–20mm), precision tapping (M2–M18), and chamfering in one clamping setup.
- Rigid Clamp System: Guideway sliding double-output fixture firmly presses the workpiece surface, mitigating vibration during heavy drilling/tapping operations.
- Automatic Tool Change Efficiency: Integrated 4-knife row-type tool holder minimizes downtime between tool transitions.
- High-Speed Axis Traversal: Rapid movement on the X-axis (30–60 m/min) and Y/Z axes (25 m/min) drastically cuts non-cutting cycle times.
- ±0.02mm Repeated Positioning Accuracy: Ensures tight tolerance control across extensive production runs.
Solved Industry Pain Points
1. Eliminating Workpiece Shaking During Heavy Machining
- Challenge: Unstable clamping on long profiles leads to drill chatter, inaccurate hole placement, and tool breakage.
- Solution: Adjustable sliding dual-output pressure cylinders adapt to varying workpiece lengths, securing the part firmly against high cutting forces.
2. Multi-Process Machine Transfer Bottlenecks
- Challenge: Moving workpieces across separate drilling, tapping, and chamfering stations increases setup times and error rates.
- Solution: 3-axis linkage paired with an automatic tool magazine executes full-cycle hole processing in a single operation.
3. High Operator Labor Dependency
- Challenge: Manual tool setup and machine operation require skilled technicians and increase operating costs.
- Solution: NC control system with CAD file import capability and support for 10,000 stored programs allows single-operator efficiency with minimal setup overhead.
