High-Efficiency Four-Spindle CNC Drilling and Tapping Machine

Industrial Mass Production Efficiency

The DUOMI DNC-1530DDTT Four-Spindle CNC Drilling and Tapping Machine is an advanced multi-axis machining center engineered specifically for high-throughput component manufacturing. Built to double productivity while maintaining extreme dimensional accuracy, this heavy-duty unit features a dual drilling shaft and dual tapping shaft configuration. By integrating multi-station processing with continuous circular loading, procurement engineers can achieve maximum throughput across aluminum, steel, brass, and alloy components.

Key Engineering Features & Core Capabilities

• Dual Drilling & Tapping Spindle System: Features two dedicated drilling spindles and two dedicated tapping spindles. The Z-axis processes two apertures on one workpiece or single apertures across two workpieces simultaneously, cutting cycle times by 50%.
• Precision Servo Drive & Absolute Control: All transmission axes are driven by high-torque absolute servo motors, achieving positioning accuracy of ≤0.02 mm and repeatable positioning accuracy within ±0.02mm.
• HIWIN Linear Guides & Ball Screws: Equipped with industrial-grade Taiwan HIWIN precision linear guideways and ball screws to ensure low-friction, high-rigidity linear movement under continuous load.
• Flexible 3-Axis CNC Control System: Supports direct CAD file imports, computer programming, and manual input via an intuitive 3-axis CNC interface, accommodating operators of all technical levels.
• Manual Pulse Generator (MPG): Integrated hand pulse control enables quick work-piece setup, fine tool positioning, and easy zero-point calibration.
• Continuous Multi-Station Workflow: Featuring a 1300mm X-axis stroke and semi-closed frame, operators can safely load and unload workpieces on dynamic left/right dual stations without pausing production.

Structural Integrity & Metrology Standards

Stress-Relieved Cast Frame

Engineered with a heavy-duty, stress-relieved base structure (approx. 1700 kg total weight), the machine absorbs operational vibrations to retain micro-scale accuracy during high-speed machining operations (X-axis rapid feed rates up to 60 m/min).

Fully Automatic Oil Cooling & Lubrication

An integrated lubrication system supplies constant oil cooling to both high-speed spindles (up to 24,000 RPM) and linear guide blocks, reducing thermal displacement and mechanical wear without requiring manual maintenance downtime.

Metrology Verification via API Laser Interferometer

Every DUOMI CNC machine undergoes rigorous factory laser calibration using USA API laser interferometers. Overall motion geometry and pitch-error compensation are pre-calibrated to strict international standards (ISO 9001 / CE compliance) before dispatch.
