Multi-Spindle CNC Drilling & Tapping Machine Manufacturer

Executive Overview: High-Throughput Multi-Spindle Machining

As a premier Multi-Spindle CNC Drilling & Tapping Machine Manufacturer, DUOMI CNC provides high-precision automated solutions designed to maximize industrial manufacturing throughput. The flagship DNC-3030DDTT integrates dual drilling and dual tapping capabilities into a single heavy-duty platform, specifically optimized for high-volume processing of long metal profiles, tubes, and sheet metal workpieces.

Featuring an expansive X-axis travel of 2800mm, Y-axis travel of 300mm, and Z-axis travel of 200mm, this unit supports flexible left-right dual-station or multi-station clamping setups. By enabling simultaneous processing across four servo-driven spindles, the system eliminates non-productive loading cycles and delivers up to 300% efficiency gains compared to single-spindle alternatives.

Key Engineering Advantages & Performance Features

1. Four Servo-Driven Spindle Array

Equipped with four independently controlled servo spindles operating from 100 to 24,000 RPM, the system enables simultaneous multi-hole processing. Each spindle delivers high torque and dynamic acceleration to optimize cycle times across varying hole diameters: * Drilling Capacity: Ø1mm – Ø16mm * Tapping Capacity: M2 – M14 * Chamfering Range: Ø1mm – Ø20mm

2. High-Rigidity Heavy-Duty Frame & Linear Motion

• Stress-Relieved Machine Base: Annealed cast structure resists dynamic deflection and damps harmonic vibrations during high-speed feed movements.
• Premium Motion Hardware: Utilizes precision HIWIN (Taiwan) linear guideways and ground ball screws to deliver fast traverse speeds (X: 30–60 m/min, Y/Z: 25 m/min).
• Absolute Servo Control: Closed-loop absolute servo motors on all motion axes guarantee a repeated positioning accuracy of ±0.02 mm without requiring zero-point homing after shutdown.

3. Advanced 3-Axis CNC Control & Programming Flexibility

The intuitive CNC controller provides seamless integration with modern CAD/CAM workflows: * Direct File Import: Import 2D CAD/DXF graphics or 3D models directly for rapid program generation. * Multi-Mode Programming: Supports automated computer programming and manual G-code input. * MPG Hand Pulse Generator: Allows micro-inch manual pulse adjustments during job setup and tool positioning.

4. Automated Thermal Management & Lubrication

• Centralized Lubrication: Fully automatic oil delivery system continuously meters lubricant to guideways and drive ball screws to minimize component wear.
• Spindle Cooling System: Integrated oil cooling system actively dissipates heat generation during high-RPM continuous operation, maintaining long-term accuracy.

Metrology & Quality Assurance Standards

To ensure conformity with strict international industrial requirements, every unit undergoes full linear axis measurement and compensation: * API Laser Interferometer Inspection: Calibrated using an API (USA) laser system to guarantee positioning tolerances within 0.02 mm over the full stroke. * Quality Standards Compliance: Built under strict ISO quality control protocols with full CE safety compliance.
