The rock-solid machine base of the SG series is your assurance of precision and durability. The choice of high-class components ensures the long-term reliability of the machine system.
The simplicity of the control and the programming itself – a hallmark of EDMs by Mitsubishi Electric – allows the operator to focus on the essential, i.e. the proper planning of the various eroding tasks. And here, too, this is aided by the intelligent control strategy with integrated job planning and an efficient evaluation of a wide range of operating data, including actual job costing.
The full standard equipment of the SG-R completes the package. A fire extinguishing system, C axis with a zero-point clamping tool, external programming software – all this is part of the standard equipment. Additional useful features enable you to tailor the configuration to your individual requirements.
