How much does the FANUC RoboCut C800iC 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-C800iC is the largest of three sizes, and tall as well as wide: 31.50 × 23.62 in (800 mm × 600 mm) of X-Y travel with 20.08 in (510 mm) of Z. It takes a workpiece up to 49.21 × 38.38 × 19.68 in (1,250 × 975 × 499.8 mm) weighing 6,614 lb (3,000 kg).
Height is what separates it from the rest of the range. The RoboCut α-C600iC stops at 310 mm (12.2 in) of Z on 600 mm (23.6 in) by 400 mm (15.7 in) of X and Y. With 20.08 in (510 mm) here, deep extrusion dies, stacked plates and tall mould cores can be cut through the full section instead of being split. U and V each travel ±100 mm, listed as 7.87 in of U-V travel, though the table gives no taper angle to go with it.
Big work does not mean coarse work on this table. Surface finish is listed at Ra 0.10 µm and wire from Ø0.004 to 0.012 in (0.10 mm to 0.30 mm) is accepted. Threading is by AWF3 and the control is the FANUC 31i-WB Plus.
The size shows up at installation. The machine weighs 12,566 lb (5,699 kg), the dielectric system holds 417 gal (1,578 L), and a full-weight workpiece adds 6,614 lb (3,000 kg) on top. Give all three figures to whoever assesses the floor, and check crane capacity over the tank for loading parts that heavy.

Strengths & Limitations
Strengths
- 20.08 in (510 mm) of Z travel, against 310 mm (12.2 in) on the RoboCut α-C600iC
- Workpieces up to 49.21 × 38.38 × 19.68 in (1,250 × 975 × 499.8 mm) and 6,614 lb (3,000 kg)
- 31.50 × 23.62 in (800 mm × 600 mm) of X-Y travel, the largest of the three sizes
- Surface finish listed at Ra 0.10 µm
- AWF3 automatic wire threading with the FANUC 31i-WB Plus control
Limitations
- At 12,566 lb (5,699 kg) with 417 gal (1,578 L) of dielectric, the floor and rigging need planning
- No taper angle is listed, only ±100 mm of U and V travel
- The table gives no cutting speed, which decides cycle time in sections up to 19.68 in tall
- A 6,614 lb (3,000 kg) workpiece needs lifting gear over the tank

Frequently Asked Questions
01
Z travel is 20.08 in (510 mm) and the maximum workpiece height is 19.68 in (499.8 mm). For comparison, the RoboCut α-C600iC has 310 mm (12.2 in) of Z.
02
X-Y travel is 31.50 × 23.62 in (800 mm × 600 mm). The largest workpiece is 49.21 × 38.38 × 19.68 in (1,250 × 975 × 499.8 mm) at up to 6,614 lb (3,000 kg), so the tank holds a plate larger than the area the wire covers in one clamping.
03
Plan for a machine weight of 12,566 lb (5,699 kg) and 417 gal (1,578 L) of dielectric, plus a workpiece of up to 6,614 lb (3,000 kg). Electrical and air requirements are not in the table and should be taken from the installation documents.
04
The RoboCut α-C400iC is the small end of the range, with 400 mm (15.7 in) of X travel and a weight of 4,840 lb (2,200 kg), against 800 mm (31.5 in) of X and 12,566 lb (5,699 kg) here. Both list the FANUC 31i-WB Plus control.
05
Wire from Ø0.004 to 0.012 in (0.10 mm to 0.30 mm), threaded automatically by AWF3. Surface finish is listed at Ra 0.10 µm; the table does not say how many passes that takes, so allow for skim cuts when estimating cycle time on tall parts.
