How much does the FANUC ROBOCUT C800iB 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 C800iB is a large-table wire EDM. The listed travels are 800 mm (31.5 in) in X, 600 mm (23.6 in) in Y and 310 mm (12.2 in) in Z, and the tank takes a workpiece of 1,250 x 970 x 310 mm (49.2 x 38.2 x 12.2 in) weighing up to 2,000 kg (4,409 lb). It has dropped off FANUC's current pages, which makes the listed figures a checklist for inspecting a used machine, not a confirmed specification.
Set beside the RoboCut α-C800iC, the plan travels are identical at 800 mm (31.5 in) by 600 mm (23.6 in), but that machine has 20.08 in (510 mm) of Z and ±100 mm on U and V. This one lists ±60 mm on U and V. Its taper rating is ±15°, quoted over the whole 310 mm height, so the angle is modest but it is available on the thickest part the machine accepts.
Unusually, the listing states a roughing rate with its conditions: about 300 mm²/min in 60 mm D2. That gives a basis for estimating cycle time in tool steel, and a number a seller can be asked to reproduce. Positioning accuracy is listed at ±0.002 mm and repeatability at ±0.001 mm, with Ra 0.18 µm after skim passes. Wire of 0.10 to 0.30 mm is fed by the AWF2 automatic wire feed under the FANUC Series 31i-WB. The machine weighs 6,500 kg (14,330 lb).

Strengths & Limitations
Strengths
- 800 mm (31.5 in) by 600 mm (23.6 in) of X-Y travel, the same plan travels as the RoboCut α-C800iC
- Carries workpieces up to 2,000 kg (4,409 lb) and 1,250 x 970 x 310 mm (49.2 x 38.2 x 12.2 in)
- ±15° taper is rated over the full 310 mm height
- Positioning accuracy of ±0.002 mm and repeatability of ±0.001 mm are listed
- A roughing rate of about 300 mm²/min in 60 mm D2 is stated with its conditions
Limitations
- Z travel is 310 mm (12.2 in), against 20.08 in (510 mm) on the RoboCut α-C800iC
- U and V travel is ±60 mm and taper is limited to ±15°
- Surface finish is Ra 0.18 µm and needs skim passes to reach it
- Dropped from FANUC's current pages, so every listed figure needs checking on the machine itself

Frequently Asked Questions
01
X and Y match at 800 mm (31.5 in) and 600 mm (23.6 in). The RoboCut α-C800iC has 20.08 in (510 mm) of Z, ±100 mm of U and V travel and the FANUC 31i-WB Plus control, while this machine lists 310 mm (12.2 in) of Z, ±60 mm on U and V and the FANUC Series 31i-WB.
02
The listed cutting speed is about 300 mm²/min when roughing 60 mm D2. Finishing is slower: the Ra 0.18 µm surface finish is listed with skim passes, which add to the cycle after the rough cut.
03
Positioning accuracy of ±0.002 mm and repeatability of ±0.001 mm. These are axis figures, not a guarantee of part accuracy, and on a used machine they are worth confirming with a test cut or a calibration report.
04
Up to 1,250 x 970 x 310 mm (49.2 x 38.2 x 12.2 in) and 2,000 kg (4,409 lb). The machine itself weighs 6,500 kg (14,330 lb), so the combined load matters when choosing where it stands.
