How much does the Fanuc Robocut Alpha C400iA cost?
Estimated price range
Our best estimate for a wire edm in this class — not a quote from Fanuc. Configuration moves it a long way.
Overview
The Fanuc Robocut Alpha C400iA is a wire EDM with listed X and Y travels of 400 x 300 mm and 220 mm of Z. The listed figures put the workpiece limit at 800 kg and the machine weight at 3,800 kg.
Z travel is the figure to read first on a wire machine, because it bounds the thickness of the block that can be cut. At 220 mm it suits die plates, punches and inserts more than tall blocks stood on end. Taper cutting is listed as ±15° / 100 mm height, enough for die clearance and draft angles, though not for steep tapers.
Wire from 0.1 to 0.3 mm is accepted. Thin wire cuts small internal radii and fine detail; thick wire carries more current and cuts faster. The listed maximum cutting speed is 400 mm²/min and the listed finish in finishing mode is 0.25 µm Ra. Those two figures come from opposite ends of the process: the first from a rough cut, the second from skim passes, and no job gets both at once. The control is listed as a Fanuc CNC dedicated to the Robocut.

Strengths & Limitations
Strengths
- Workpieces up to 800 kg on 400 x 300 mm of X and Y travel
- Listed surface finish of 0.25 µm Ra in finishing mode
- Accepts wire from 0.1 to 0.3 mm in diameter
- Taper cutting to ±15° / 100 mm height
Limitations
- Z travel is 220 mm, which limits workpiece thickness
- Taper is limited to ±15° / 100 mm height
- The 400 mm²/min cutting speed is a maximum; finishing to 0.25 µm Ra takes additional slower passes

Frequently Asked Questions
01
Z travel is listed at 220 mm, and that bounds the workpiece thickness. X and Y travels are 400 x 300 mm and the maximum workpiece weight is 800 kg, so heavy but fairly flat blocks are the natural fit.
02
The listed wire diameter range is 0.1 to 0.3 mm. Smaller wire gives tighter inside corners and narrower slots at lower cutting speed; larger wire cuts faster. The listed maximum cutting speed is 400 mm²/min.
03
Surface finish is listed at 0.25 µm Ra in finishing mode, which means after skim passes, not from the first cut. Maximum taper is ±15° / 100 mm height.
