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.”

Dubral, a Portuguese company specialising in the manufacture of aluminium and PVC carpentry products such as hinges, once again trusts ONA as its supplier of EDM machines. The acquisition of the ONA AV35 model has allowed the company to improve precision in its cutting and raise the standard of quality in its manufacturing process, increasing efficiency and productivity.

In Dubral’s constant search for improvements it faced the challenge of finding a solution that guaranteed maximum precision and quality, with a specific effective travel of 600 x 400 x 400 mm. All this without compromising efficiency and maintaining minimal maintenance costs. In response to this demanding requirement, the 120-employee company turned to ONA.

The solution presented by ONA was its AV35 wire EDM, equipped with a mineral filter. This machine, which incorporates the latest EDM technology, met all the required specifications, offering high performance and low maintenance costs. With the implementation of the AV35, Dubral can make precision cuts in special alloys, raising the quality standard of its manufacturing process.

“It’s very gratifying for us to arrive at our premises every morning and witness the way in which the ONA machine continues working,” say Dubral’s executive directors Carla Costa and João Costa.

The AV35 model is not the only ONA EDM machine present on site. Dubral had already demonstrated its trust in the manufacturer with the previous acquisition of an NX3 die-sink EDM. This latest collaboration reflects the company’s satisfaction with the performance, quality and reliability of ONA products.

The CHMER UA432L green energy three-in-one wire cutting machine has won the 33^rd Taiwan Excellence Gold Award, while its GV5043L high-precision wire cutting machine won the Taiwan Excellence Award. Both machines shine together, meeting the smart, green energy and high-precision manufacturing needs of precision moulds and parts processing.

CHMER is the first wire cutting machine manufacturer in Taiwan to obtain ISO14955 green machine tool certification. The UA432L is also the first wire cutting machine in Taiwan to receive the Green Machine Tool Energy Saving Gold Mark.

General manager Wang Chenhong of Qinghong Mechatronics says: CHMER actively seeks innovative solutions for non-traditional processing and green intelligent manufacturing. The award-winning honours of UA432L and GV5043L affirm our unremitting pursuit of smart machinery and green machine tools. We hope to help our customers improve precision machining and production efficiency through innovation and respond to the global net-zero carbon emission challenge.”

CHMERs’ UA432L demonstrates its strength in energy conservation and carbon reduction from multiple aspects, including: a new three-in-one design that greatly reduces footprint, which can be 20% less than traditional models; the ‘High-Efficiency Energy Management System’ (HEMS) that reduces overall processing energy consumption by 40%; and a built-in green processing mode which cuts copper wire consumption by 42%

The GV5043L linear motor-driven wire cutting machine focuses on high-end applications. It features independently developed linear motor technology to ensure friction-free, backlash-free and low-energy operation, making it suitable for the manufacture of complex parts and precision moulds. The machine combines high precision and stable performance, says CHMER.

Looking ahead, CHMER will focus more on new business opportunities in the machine tool industry using AI and further energy-saving technologies.
