In a world where precision determines success or failure, Mitsubishi Electric says it is setting new standards in wire EDM with the company’s latest MX900 series. What makes this machine special is not just its accuracy of less than 1 µm – it is the combination of advanced technologies that make this precision possible in the first place.

The heart of the MX900 is its well-thought-out gantry design, where the massive machine bed made of spheroidal cast iron is completely decoupled from all peripheral units. This innovation virtually eliminates all vibrations and thermal influences. The eight-fold mounted linear guides with precisely executed mounting surfaces ensure smoothness and virtually no running resistance.

Tubular direct drive technology operates completely contactless and is therefore wear-free. It converts electrical energy directly into motion – without mechanical intermediate stages. Unlike conventional drives, there is no disruptive cogging torque that could impair precision. Communication takes place via polymer fibre optic cables, enabling 400% faster data transmission. The result: positioning accuracies below ±1 µm over the entire travel path – Mitsubishi Electric provides a 12-year manufacturer‘s warranty on this precision.

The MX900 thinks thermally ahead: even before heat can develop, the machine compensates accordingly. The sophisticated two-column concept combines the physical decoupling of heat sources such as pumps and aggregates with predictive temperature control. This forward-looking strategy is crucial, as thermodynamic processes exhibit a certain inertia – pure reactive adjustment would come too late for the required accuracies.

Mitsubishi’s newly developed nPV (Nano Pulse V-Power) generator works with pulses in the nanosecond range and produces a uniform, controlled spark pattern across the entire erosion path. This enables surface qualities up to Ra 0.04 µm in carbide and below Ra 0.06 µm in steel.

Rotary indexing table specialist Carl Hirschmann GmbH says it was thrilled to attend the recent GF Technology Forum 2025, a two-day event for end users at EDM machine manufacturer GF Machining Solutions’ facility in Schorndorf, Germany. Hirschmann’s design manager Eugen Grossmann praised the event, which offered a great opportunity to exchange ideas and explore the potential of new technology.

Participants were able to choose from a total of 54 practical workshop slots at workshop and CAM level, including 31 different topics. In addition to practical modules, break-out stations offered the opportunity to obtain specific information about innovative technologies and engage in direct discussions with +GF+ experts and exhibitors.

“Especially in the current very challenging situation, the continuous improvement of production processes is of crucial importance for competitiveness, because the most efficient way to boost manufacturing is often to optimise the use of existing resources,” says Hirschmann CTO Rainer Harter. “As a partner and co-exhibitor, we were delighted to have a stand on site. In addition, our design manager Eugen presented the advantages of our newly developed FJRD-120 rotary dividing table to the participants in one of the numerous workshop slots.”

Hirschmann sales manager Jürgen Früh adds: “The high level of organisational effort was evident in every detail of the event – from the smooth execution to the first-class catering and the evening event, which provided the participants with an all-round very successful technology forum We’re already looking forward to the 2026 event – full of innovation, team spirit and enthusiasm.”
