4-Axis CNC Drill & Tap Machine for Steel Profiles

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 ±0.01 mm, 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
