Executive Overview
The DUOMI 4-Axis CNC Drill & Tap Machine (Model: DNC-3003DDDD(R1)) is engineered specifically for heavy-duty, high-volume machining of structural steel profiles, square tubing, and round steel stock. By integrating drilling, tapping, chamfering, and milling into a single setup with 360° A-axis rotation and a 3000mm X-axis stroke, this machine eliminates frequent workpiece re-clamping and reduces total machining cycles by up to 60%.
Manufactured under CE compliance standards, the system delivers exceptional repeatable positioning accuracy of ±0.02mm, driving scrap rates down from industry averages of 8% to just 0.2%.
Key Performance Indicators & Technical Advantages
- Multi-Process Integration: Combines drilling (1–16mm dia.), chamfering (1–20mm dia.), tapping, and face milling in a single clamping cycle.
- High-Speed Axis Travel: X-axis traverse speeds up to 60 m/min and Z-axis speeds of 25 m/min ensure minimal non-cutting idle time.
- Extended Machining Envelope: X3000mm × Z200mm stroke with full 360° continuous A-axis rotation handling tube/profile clamping diameters from 10mm to 200mm.
- Dual Spindle Power: Features dual vertical spindles (3.7 kW × 2) and dual horizontal spindles (2.3 kW × 2) operating at variable speeds from 100 to 3,000 RPM.
- ROI & Defect Reduction: Real-world automotive and structural steel manufacturing data proves a drop in hole-positioning defects from 8% to 0.2%, yielding upwards of $500,000 in annual raw material savings.
Industrial Applications & Market Sectors
- Structural Steel & Heavy Fabrication: Beam drilling, gusset plate alignment, and frame assembly holes.
- Automotive & Electric Vehicle (EV) Mobility: Customized steel chassis frames, battery tray supports, and cylinder head oil passages.
- 3C Electronics & Hardware: High-density mounting holes and threaded connections in complex metal housings.
- General Machinery & Energy Sector: Precision gear plates, bearing lubrication holes, and round stock pipe processing.
Operational Flexibility & Control
- Seamless CAD Import: Directly import standard CAD/CAM files, generate NC code automatically, or program manually via an intuitive graphical touchscreen HMI.
- Substantial Program Memory: On-board memory stores up to 10,000 distinct machining programs for instant product changeovers.
- Automation-Ready: Supports external signal handshake for integration with robotic loading/unloading arms to facilitate 24/7 unmanned lights-out manufacturing.
