Overview

The Mitsubishi MV2400S is a large-table CNC wire EDM from Mitsubishi Electric's Machine Tool Division, designed for precision cutting of large die sets, progressive die tooling, and large aerospace structural features. The MV2400S offers a 600x400 mm XY travel with a UV taper axis capable of ±45° over 300 mm workpiece height, making it one of the most capable production wire EDMs in the large-format segment. Mitsubishi Electric is one of the world's largest wire EDM manufacturers and their MV series uses the GR digital generator, which Mitsubishi claims delivers 20-30% faster cutting speed compared to their previous series with equivalent surface finish quality. The GR generator also includes Mitsubishi's AI Automatic Expert System, which learns from previous cuts and automatically adjusts machining conditions for similar materials and geometries in subsequent programs. The machine is operated via Mitsubishi's own B-board controller with full G-code compatibility, integrating with offline programming systems including Mitsubishi's own EIDOS software.

Frequently Asked Questions

01 What is Mitsubishi's AI Automatic Expert System?

The AI Expert System monitors current machining conditions and compares them to historical data accumulated from previous jobs. It automatically selects optimal generator parameters for new materials, thicknesses, and finish requirements based on this learning database, reducing setup time for experienced operators.

02 Does the MV2400S support automatic wire threading?

Yes. The MV2400S includes automatic wire threading (AWT) that rethreads the wire at break points or at new start locations without operator intervention, enabling unattended multi-start programs overnight.

03 What is the maximum workpiece height the MV2400S can accommodate?

The Z-axis provides 375mm of headstock travel, accommodating workpiece heights up to approximately 350mm with standard setup. The UV taper system is rated to ±45° over a 300mm workpiece height reference.
