Overview

The Fanuc Robocut C600iA is a large-format wire EDM machine designed for high-precision cutting of oversized workpieces in aerospace, automotive tooling, and heavy die/mold applications. With a generous X/Y travel of 600 x 400 mm and the ability to handle workpieces weighing up to 1,000 kg, it addresses the demanding requirements of large stamping dies, progressive dies, and thick extrusion tooling.

At its core, the C600iA runs Fanuc's proprietary CNC-dedicated wire EDM control, offering an intuitive conversational interface alongside full ISO code programming. The machine's intelligent pulse control technology minimizes wire breakage while maximizing cutting speed, enabling operators to maintain high throughput on complex 3D taper cuts and multi-pass finishing operations.

Fanuc's i-CUTTM active control continuously monitors discharge conditions and adjusts power parameters in real time, achieving surface finishes down to Ra 0.2 µm in fine finishing mode. The automatic wire threading system (AWT) operates reliably even in submerged conditions, dramatically reducing downtime during unattended overnight runs.

The C600iA is built on a robust cast-iron structure with thermally compensated ballscrews and linear scales, ensuring long-term accuracy across extended cutting sessions. It is a compelling choice for shops that need maximum workpiece capacity without sacrificing the surface quality and precision expected from Fanuc's Robocut line.

Frequently Asked Questions

01 What wire diameters does the Robocut C600iA support?

The C600iA accepts wire diameters from 0.1 mm to 0.3 mm, with 0.25 mm brass wire being the most common choice for general-purpose cutting. Thinner 0.1 mm wire is used for fine-detail or small-radius features.

02 Can the C600iA run unattended overnight?

Yes. The machine's automatic wire threading (AWT) system re-threads after a wire break without operator intervention, and Fanuc's active discharge control reduces break frequency, making extended unattended runs highly practical.

03 How does the C600iA's cutting speed compare to competitors?

At up to 500 mm²/min, the C600iA is competitive with other premium large-format wire EDMs. Actual throughput depends on material, thickness, and required surface finish, but Fanuc's pulse control technology helps maintain speed while protecting wire integrity.
