High-Precision Industrial CNC Drilling and Tapping Machine

High-Performance CNC Drilling and Tapping Solutions

The DUOMI CNC Drilling and Tapping Machine (Model DNC-1530D) is designed to deliver superior precision, rapid cycle times, and operational reliability for industrial manufacturing. Combining drilling, milling, tapping, and chamfering into a unified automated platform, this machine provides an ideal solution for processing aluminum extrusions, steel, copper, iron, brass, and alloy components.

Built on a heavy-duty stress-relieved bed and validated through API laser interferometer calibration (USA), the machine guarantees overall accuracy within 0.02 mm and repeated positioning accuracy of ±0.02mm.

Core Engineering & Key Technical Features

1. Precision Single Servo-Driven Spindle

Powered by a high-performance servo motor, the main spindle delivers high torque at lower speeds and rapid acceleration up to 24,000 RPM. This dynamic range allows smooth drilling and rigid tapping across non-ferrous alloys and heavy-duty steel parts.

2. Advanced 4-Axis CNC Control System

The machine features a flexible 4-axis CNC controller supporting multiple programming methods: - Direct CAD file import (DXF/G-code) - Computer-assisted CAM programming - On-site manual programming

With storage capacity for approximately 10,000 programs and support for external automation signals, operators can quickly set up jobs and execute short runs or high-volume continuous output.

3. Stress-Relieved Rigid Machine Structure

The heavy-duty machine body undergoes thermal stress relief to eliminate internal material tension. This rigid structural base absorbs micro-vibrations during high-speed cutting, ensuring long-term thermal stability and tool longevity under continuous 24/7 industrial operating conditions.

4. Premium Linear Motion Components

Equipped with HIWIN (Taiwan) high-rigidity linear guideways and ball screws, the motion control system maintains ultra-smooth positioning along the X (1500mm), Y (300mm), and Z (200mm) axes, with rapid traverse speeds reaching up to 60 m/min on the X-axis.

5. Absolute Servo Motor Drive & MPG Control

• Absolute Servo Motors: Eliminate the need for zero-point return after power disruptions, saving setup time and preventing axis offset errors.
• Manual Pulse Generator (MPG): Enables fine manual pulse tuning for effortless workpiece alignment and precise tool setting.

6. Automatic Oil Cooling & Centralized Lubrication

An integrated automatic cooling and lubrication system delivers consistent oil supply directly to spindle bearings and linear guides, minimizing thermal growth, reducing component friction, and eliminating manual routine greasing maintenance.
