Overview
The Hyundai WIA i-CUT400TD is a high-speed tapping and drilling center designed for rapid production of small-to-medium parts requiring numerous holes, taps, and light milling operations. The TD (Tapping/Drilling) designation signals a machine optimised for short-cycle, high-throughput work where tool-change speed and rapid traverse rates matter more than heavy cutting capability. The i-CUT400TD competes directly with the Fanuc Robodrill, Brother Speedio, and Haas DT-1 in the high-speed tapping center segment.
The machine features axis travels of 400 x 300 x 300 mm (15.7 x 11.8 x 11.8 in), which is compact but well-suited for the small electronics housings, connector bodies, valve blocks, and automotive components that define this machine class. The BT30 spindle reaches 20,000 RPM with 5.5/3.7 kW (7.5/5 hp), delivering the high-speed capability needed for small-diameter drilling, tapping, and finish milling in aluminium and light alloys.
Rapid traverse rates of 60 m/min (2,362 ipm) in all axes are among the fastest in the compact tapping center class. The 21-tool servo-driven ATC delivers chip-to-chip times under 1.5 seconds, which is critical when programs involve 15-20+ tool changes per part. The combination of fast rapids, fast tool changes, and high spindle speed produces short cycle times that justify the machine in high-volume production cells.
The Fanuc 0i-MF Plus control is standard, providing rigid tapping capability, nano-interpolation, and compatibility with all major CAM systems. At an estimated $60,000-$90,000 new, the i-CUT400TD offers an attractive entry point for shops adding high-speed tapping and drilling capacity without the premium pricing of Fanuc Robodrill or Brother Speedio machines.

Strengths & Limitations
Strengths
- 60 m/min rapid traverse in all axes minimises non-cutting time on multi-hole tapping and drilling programs
- 20,000 RPM BT30 spindle enables high surface speeds on small-diameter tools for fast aluminium machining
- Sub-1.5-second chip-to-chip tool changes keep cycle times low on programs with 15-20+ tool changes per part
- Compact footprint fits into tight production cells and allows multiple machines in the floor space of one large VMC
- Competitive pricing at $60K-$90K undercuts Fanuc Robodrill and Brother Speedio by 15-30%
- Fanuc control with rigid tapping provides reliable, repeatable thread quality at high speeds
Limitations
- BT30 taper limits cutting force capability and is not suitable for heavy milling in steel or hard materials
- 5.5 kW spindle power restricts material removal rate compared to BT40 VMCs for heavier cuts
- 300 mm Y and Z travel constrains workpiece size to small-to-medium components only
- 21-tool magazine capacity may be limiting for complex programs requiring more unique tools

Frequently Asked Questions
01
Both are high-speed BT30 tapping centers with similar travel envelopes. The Fanuc Robodrill has a stronger brand reputation and denser service network. The i-CUT400TD offers competitive specs at a lower price point, typically 15-30% less than a comparably equipped Robodrill. Both run Fanuc controls. The Robodrill has a slight edge in chip-to-chip speed and high-speed contouring accuracy.
02
The i-CUT400TD excels in aluminium, aluminium alloys, brass, copper, and plastics where high spindle speed and fast rapids translate directly to productivity. It can machine mild steel and stainless steel at reduced parameters, but the BT30 taper and 5.5 kW spindle are not designed for heavy steel cutting. For steel-dominant work, a BT40 VMC is a better choice.
03
Rigid tapping synchronises spindle rotation with Z-axis feed to cut threads without a floating tap holder. This produces more accurate threads, eliminates tap holder cost, and allows higher tapping speeds. On a machine like the i-CUT400TD where tapping is a primary operation, rigid tapping capability is essential for achieving the short cycle times the machine is designed for.
04
No. The i-CUT400TD is a specialised high-speed drilling and tapping machine, not a general-purpose VMC. Its BT30 spindle and compact travel envelope are designed for light-duty, high-speed operations on small parts. For heavier milling, larger parts, or general-purpose 3-axis work, a BT40 machine like the Hyundai WIA KF4600 is more appropriate.
