DNC-630DR Multi-Angle Automatic Rotating CNC Drilling Machine

Industrial Overview & High-Precision Machining Capabilities

The DNC-630DR Multi-Angle Automatic Rotating CNC Drilling Machine from DUOMI CNC is an advanced four-axis machining solution designed specifically for high-speed small hole drilling (0.2 mm to 4.0 mm) and precision tapping. Engineered to handle round tubes, square tubes, and complex non-standard profiles, this compact multi-axis drilling center delivers exceptional throughput and tight-tolerance performance across high-volume B2B manufacturing operations.

Featuring an integrated 360° servo-driven rotary axis combined with a high-rigidity structural frame, the DNC-630DR delivers an ultra-precise repeatability of ±0.02mm and maximum X-axis rapid traverse speeds up to 60 m/min.

Core Engineering Features & Technical Advantages

1. High-Speed Precision Servo Spindle System

• Broad Speed Range: Configurable high-speed servo spindle operating from 1,500 to 60,000 RPM tailored to micro-drilling demands.
• Vibration Damping: Engineered for minimal runout and reduced thermal expansion, ensuring long tool life when machining delicate micro-holes in non-ferrous and hard alloys.
• Servo Torque Control: Maintains consistent torque output during synchronous drilling and tapping cycles.

2. 360° Servo-Controlled Rotary Axis & Dual Station Configuration

• Harmonic Reducer Integration: Driven by high-precision absolute servo motors paired with low-backlash harmonic reducers for accurate angular indexing at any degree.
• Multi-Angle Flexibility: Complete 360-degree positioning enables multi-side drilling on round tubes (10–70 mm clamping diameter) without manual re-clamping.
• Optional Dual Station Processing: Maximizes machine uptime through dual station operation, significantly reducing cycle times per workpiece.

3. Structural Integrity & Linear Motion System

• Stress-Relieved Heavy Cast Base: Built with a high-rigidity, stress-relieved frame structure that absorbs cutting forces and dampens vibration during continuous 24/7 industrial production.
• HIWIN Precision Linear Guides & Ball Screws: Equipped with original Taiwan HIWIN guideways across all linear axes for smooth dynamic response and sustained alignment.
• Absolute Servo Control: All motion axes utilize absolute optical encoders, eliminating the need for homing operations and securing positioning accuracy within 0.02 mm.

4. Fully Automatic Lubrication & Thermal Management

• Automatic Oil Cooling: Micro-mist and automatic cooling systems stabilize spindle temperatures during sustained high-RPM operation.
• Guided Lubrication: Centralized automatic oil lubrication continuously protects ball screws and linear guides, prolonging machine service life and minimizing maintenance overhead.
