How much does the FANUC RoboCut α-C400iC 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 α-C400iC is the smallest of three sizes of this wire EDM: 15.75 in × 11.81 in of X-Y travel, a 1,100 lb (500 kg) workpiece limit and a machine weight of 4,840 lb (2,200 kg). X travel is also given as 400 mm (15.7 in). The RoboCut α-C600iC, the next size up, has 600 mm (23.6 in) of X and weighs 7,937 lb (3,600 kg).
The tank accepts far more plate than the axes cover. A workpiece can measure 28.74 in × 24.80 in × 9.84 in (730 mm × 630 mm × 250 mm), yet the wire reaches a 15.75 in × 11.81 in window of it in one setup. That is useful for cutting a cluster of openings in an oversize plate, as long as the datum scheme allows for re-clamping to reach the rest.
Height needs a second look. The table lists 20.08 in (510 mm) of Z travel but caps the workpiece at 9.84 in (250 mm) tall, so plan around the workpiece figure and have the Z travel confirmed on the quotation. Taper is ±15°, with 4.72 in (119.8 mm) of U-V travel behind it.
Wire from Ø0.004 to 0.012 in is listed, threading is by AWF3 and the control is the FANUC 31i-WB Plus. The dielectric system holds 145 gal (550 L), and that fluid sits on the floor along with the 4,840 lb (2,200 kg) machine, so give both figures to whoever checks the foundation.

Strengths & Limitations
Strengths
- Accepts a workpiece up to 28.74 in × 24.80 in × 9.84 in (730 mm × 630 mm × 250 mm) and 1,100 lb (500 kg)
- Lightest of the three sizes at 4,840 lb (2,200 kg); the RoboCut α-C600iC weighs 7,937 lb (3,600 kg)
- AWF3 automatic wire threading, run from the FANUC 31i-WB Plus control
- Wire range of Ø0.004 to 0.012 in for both fine detail and general die work
- Taper cutting to ±15° with 4.72 in (119.8 mm) of U-V travel
Limitations
- X-Y travel of 15.75 in × 11.81 in covers only part of the 28.74 in × 24.80 in plate the tank accepts, so large plates take more than one setup
- Taper is listed at ±15°, which rules out steeper relief angles
- Workpiece height is capped at 9.84 in (250 mm), although Z travel is listed as 20.08 in (510 mm)
- No surface finish or cutting speed figure appears in the table

Frequently Asked Questions
01
X-Y travel is 15.75 in × 11.81 in, with X also given as 400 mm (15.7 in). U-V travel is 4.72 in (119.8 mm). Z travel is listed as 20.08 in (510 mm), which is more than the 9.84 in (250 mm) maximum workpiece height, so confirm the Z figure when you ask for a quotation.
02
Up to 28.74 in × 24.80 in × 9.84 in (730 mm × 630 mm × 250 mm) and 1,100 lb (500 kg). The plan size is larger than the 15.75 in × 11.81 in the axes travel, so a full-size plate cannot be reached everywhere in a single clamping.
03
Size and weight. This machine has 400 mm (15.7 in) of X travel and weighs 4,840 lb (2,200 kg); the RoboCut α-C600iC has 600 mm (23.6 in) of X, 400 mm (15.7 in) of Y and weighs 7,937 lb (3,600 kg). Both tables name the 31i-WB Plus control.
04
Wire from Ø0.004 to 0.012 in, threaded automatically by the AWF3 system. The table does not state a minimum start-hole size for this model, so ask if your parts depend on small start holes.
05
The machine weighs 4,840 lb (2,200 kg) and the dielectric system holds 145 gal (550 L). The table gives no electrical or air requirements, so those have to come from the installation documents supplied with the quotation.
