Overview
The FANUC Robodrill α-D14MiBADV Plus is the medium-bed Advanced variant in FANUC’s current-production DiB Plus platform. The Mi designation places it in the sweet spot with 500 mm X-travel and 400 mm Y-travel, while ADV delivers the fastest tool change times. The 14-tool turret version is the most common entry point for the Robodrill ecosystem.
The 500 x 400 x 400 mm travel envelope covers the majority of small-to-medium production parts in automotive, electronics, medical, and general manufacturing. This bread-and-butter configuration accounts for a significant share of nearly half a million Robodrills installed worldwide. The D14 means 14 tools in the servo-driven turret, changing at 0.7 seconds tool-to-tool and 1.3 seconds chip-to-chip.
Spindle options include 10,000 RPM standard, 24,000 RPM high-speed for aluminum, high-torque at approximately 100 Nm for steel, and 12,000 RPM tapping-optimized. All BT30 taper. Rapids hit 54 m/min. The 31i-B Plus control provides high-speed look-ahead, AI contour control, and nano interpolation.
At approximately 2,200 kg, it requires roughly 2,200 x 2,100 mm of floor space. New pricing is 0,000-30,000. Methods Machine Tools distributes in North America. It competes directly with the Brother Speedio S500X2, Haas DT-2, and Haas DM-2.

Strengths & Limitations
Strengths
- 500 x 400 mm X/Y travel covers the majority of small-to-medium production parts while maintaining speed
- 0.7-second tool-to-tool change saves 15-20 minutes per shift versus conventional VMCs
- 54 m/min rapids minimize non-cutting time over thousands of parts
- High-torque 100 Nm spindle option enables steel machining unusual for BT30 platforms
- 31i-B Plus with AI contour control delivers excellent surface finish on 3D contours
- Nearly 500,000 Robodrills installed ensures exceptional parts availability and service
Limitations
- BT30 taper limits rigidity for heavy roughing in hardened steel and cast iron
- 14-tool turret may be insufficient for complex parts; D21 has 21 tools
- FANUC 31i has a steeper learning curve than Haas or Mazak controls
- 400 mm Z-travel may restrict tall fixtures or deep-cavity parts

Frequently Asked Questions
01
D14 has 14 tools; D21 has 21 plus B5 five-axis-ready control. D21 has 330 mm Z vs 400 mm. Choose D14 for simpler parts; D21 for complex or 5-axis work.
02
ADV achieves 0.7s tool-to-tool vs 0.9s standard. Includes high-speed look-ahead, AI contour control, and nano interpolation as standard.
03
Yes, especially with the 100 Nm high-torque spindle. Shops cut mild steel, 4140, stainless with lighter cuts at higher speeds.
