Mitsubishi SG-R: Superior Machining Performance


SG-R – Precision Empowered

The solid machine base of the SG series guarantees precision and durability. Opting for top-notch components ensures the machine system's enduring reliability.

The straightforward control and programming, a hallmark of Mitsubishi Electric's EDMs, enable operators to concentrate on crucial tasks, like planning eroding assignments effectively. Additionally, an intelligent control strategy, coupled with integrated job planning and efficient evaluation of various operational data, streamlines the process, including job costing.

Completing the package, the full standard equipment of the SG-R includes a fire extinguishing system, C-axis with a zero-point clamping tool, and external programming software. These components are essential parts of the standard setup, with supplementary features available for tailoring the configuration to individual requirements.
