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 α-C1200iB is a large-format wire EDM. The listed figures give 1,200 mm (47.2 in) of X travel, 800 mm (31.5 in) of Y and 400 mm (15.7 in) of Z, with a tank that accepts a workpiece of 1,600 x 1,200 x 400 mm (63.0 x 47.2 x 15.7 in) weighing up to 4,000 kg (8,818 lb).
Plan area is what this machine is for. The RoboCut α-C800iC is listed with 800 mm (31.5 in) of X and 600 mm (23.6 in) of Y, so X travel here is half as long again. Height is a different matter: the RoboCut α-C800iC table shows 20.08 in (510 mm) of Z against 400 mm (15.7 in) on this one, so a tall block is no reason to pick the larger machine. U and V each travel ±150 mm (±5.91 in), and the maximum taper angle is ±30° at 100 mm height.
Wire from 0.10 to 0.30 mm is listed, with a cutting accuracy of ±0.002 mm and a surface finish of Ra 0.15 µm that the table qualifies as achievable with skim passes. Budget those extra passes when a drawing calls for that finish over a long profile. Threading is by AWF3, listed as submerged capable, and discharge is managed by AI Pulse Control II on the Fanuc Series 31i-WB control. The dielectric is deionized water.
The machine weighs approx. 12,000 kg (26,455 lb) before a workpiece of up to 4,000 kg (8,818 lb) and the water go in, so floor loading and crane access need settling early.

Strengths & Limitations
Strengths
- 1,200 mm (47.2 in) of X travel and 800 mm (31.5 in) of Y for large die plates and mould bases
- Accepts workpieces up to 1,600 x 1,200 x 400 mm (63.0 x 47.2 x 15.7 in) and 4,000 kg (8,818 lb)
- U and V travel of ±150 mm (±5.91 in), against ±100 mm on the RoboCut α-C800iC
- AWF3 automatic wire threading, listed as submerged capable
- Listed cutting accuracy of ±0.002 mm, with Ra 0.15 µm achievable with skim passes
Limitations
- Z travel is 400 mm (15.7 in), less than the 20.08 in (510 mm) listed for the smaller RoboCut α-C800iC
- Machine weight of approx. 12,000 kg (26,455 lb) calls for a checked floor and heavy rigging
- Taper cutting is bounded at ±30° at 100 mm height
- The Ra 0.15 µm finish is stated for skim passes, which add cutting time on a large profile

Frequently Asked Questions
01
The listed maximum workpiece is 1,600 x 1,200 x 400 mm (63.0 x 47.2 x 15.7 in) and 4,000 kg (8,818 lb). The wire reaches less than that: travels are 1,200 mm (47.2 in) in X, 800 mm (31.5 in) in Y and 400 mm (15.7 in) in Z, so a blank at the maximum size can only be cut inside that window in one setup.
02
The listed maximum taper angle is ±30° at 100 mm height, produced by U and V axes that each travel ±150 mm (±5.91 in). Taper capability depends on workpiece thickness, so read the angle and the height together when checking a part against it.
03
The RoboCut α-C800iC is listed with 800 mm (31.5 in) of X, 600 mm (23.6 in) of Y and 20.08 in (510 mm) of Z, with ±100 mm on U and V. This model has 1,200 mm (47.2 in) of X, 800 mm (31.5 in) of Y and ±150 mm (±5.91 in) on U and V, but less Z at 400 mm (15.7 in).
04
Wire diameter runs from 0.10 to 0.30 mm. Cutting accuracy is listed at ±0.002 mm and surface finish at Ra 0.15 µm, the latter stated as achievable with skim passes. The dielectric is deionized water and threading is by AWF3.
