When it comes to single or multi-hole high-speed EDM drilling, the Engineering Technology Group (ETG) says it is breaking the boundaries of convention with the introduction of the Winbro HSD6-III high-speed EDM drilling system.

Designed and manufactured in the UK by the Winbro Technologies Group, the HSD6-III high-speed EDM system is said to offer industry-leading performance while maintaining stringent metallurgical requirements that are commonplace in the aerospace and IGT markets. Winbro’s HSD6-III is for the machining of cooling holes, forms and features in turbine blades, nozzle guide vanes, seal segments and other components that require high-speed EDM drilling. The machine is capable of producing round, elliptical and 2D/3D shaped diffusers.

Offering production rates up to five times faster than conventional EDM machines, the Winbro HSD6-III is suitable for processing round holes from 0.3 to 3 mm diameter with a maximum depth up to 100 mm. Precision is assured with Winbro’s advanced and patented six-point probing system.

The work envelope of the Winbro HSD6-III offers an X, Y and Z axis of 200 x 200 x 250 mm that can accommodate workpieces up to 225 x 225 x 225 mm. In addition, the rotary A axis of ±185°, B axis of 135° +100° and a rotary C axis of ±8° enables component interpolation for complete five-sided part processing in a single set-up.

The tooling configuration of the Winbro HSD6-III is flexible to suit the demands of the end-user with the choice of a single-point rotational or static electrode for non-line-of-sight, or (for high-productivity environments) a multi-tool option with up to 45 sensed electrodes.

Chesterfield-based manufacturer CBE+ has recently acquired new machinery and team members from aerospace industry leader Aerodyn. The investment comprises three EDM machines – a Mitsubishi MV2400S and two Mitsubishi FX20 – along with a team of two operators. These machines will add new wire EDM capabilities that complement CBE+’s existing range of CNC milling and turning services. CBE+ will use the machines to create tapers, small radii, complex contours and surface finishes within tolerances of just a few microns, either as a stand-alone subcontract offering or as part of supply-complete projects.

The machines, owned previously by Aerodyn, have been programmed and operated by two technical engineers. Ensuring a comfortable transition for these experienced and knowledgeable employees has been a key priority, as they move from Aerodyn to CBE+.

Operations director Lindsay Atkins says: “These machines increase our core capabilities and add to our existing offering, which revolves around precision engineering, electroless nickel plating, gear manufacture and metal testing. We can provide any of our services independently or combine multiple capabilities to create tailored, integrated supply chain solutions. The new employees are vital to the success of this new investment and I’m pleased to see them settle in so quickly.”

Fabio Cosenza, business development manager, adds: “This acquisition comes with a long-standing portfolio of customers, many in the aerospace sector, a target market for CBE+. Enhancing the existing relationships being transferred from Aerodyn is key and will be pivotal in supporting and raising the profile of our business, and allowing us to showcase our multiple capabilities.”

At the EMO Milano 2021 exhibition earlier this month, GF Machining Solutions highlighted EDM technologies designed to help manufacturers increase productivity and accuracy.

The show marked the unveiling of the new AgieCharmilles CUT P Pro series of wire EDM machines that are designed for increased productivity. Included in the series is the CUT P 350 Pro, 550 Pro and 800 Pro with robust designs and an intuitive HMI, as well as several automation options for lights-out operation.

At EMO Milano, GF Machining Solutions also announced the AgieCharmilles CUT X series of wire EDM machines, featuring new technologies that significantly increase operating precision. This new range, which includes the CUT X 350 and CUT X 500, is capable of offering extreme pitch positioning and contouring capabilities for high part quality, says the company.

For mould makers in microelectronics, telecommunications, medical technology, connectors and optical systems, GF Machining Solutions demonstrated its AgieCharmilles FORM X 600 die-sinking EDM at EMO. The machine delivers positioning accuracy within 1 μm, and general machining accuracy on the workpiece down to 5 μm, combining speed and precision.

The new Uniqua HMI, available for the CUT P Pro and the CUT X series, capitalises on more than a century of EDM technology, with optimal functionality and ergonomics in a 19-inch vertical touchscreen, full keyboard and mouse. It is suitable for every skill level, every approach and every user, reports GF Machining Solutions.

For the utmost compatibility, Uniqua supports legacy file types from various EDM manufacturers. The HMI also creates, imports, modifies and executes sequential (ISO-based) and object-oriented (dynamic) programs from previous versions of VISION and AC CUT. With offline and at-the-machine programming, ISO-based functionality and object-oriented programming, Uniqua provides a comprehensive graphic tool with integrated CAM, while ensuring compatibility with major CADCAM programs.

With up to 30% of its machined components manufactured from hard metals, Longford, Ireland-based N&E Precision acknowledged a requirement for EDM technology to complement its extensive CNC machine shop facilities. In September 2019, the subcontract manufacturer invested in its first Mitsubishi wire EDM machine and, such was its success that the company has now purchased a second Mitsubishi machine from the Engineering Technology Group (ETG).

Discussing the arrival of the first Mitsubishi wire EDM machine, N&E Precision joint managing director Noel Farrell recalls: “As a first-time EDM user, ETG’s Scot Elsemere was a major factor in our decision process. He provided expert advice, demonstrations and feedback. The technology and new software interface with the Mitsubishi MV2400R were also huge factors, but our decision was sealed by a number of recommendations from trusted contacts in the industry.”

With the company outsourcing a considerable amount of work, the Mitsubishi MV2400R immediately stemmed the flow.

“Our lead times for many components fell from weeks to 2-4 days, with some parts turned around in less than 24 hours,” says Farrell. “This wouldn’t have been possible with an external subcontract supplier involved.”

With the first Mitsubishi MV2400R making such an impact, the company invested in a second machine, a Mitsubishi MV1200R.
“The two Mitsubishi machines have added greater flexibility to our business,” states Farrell. “Some parts have tight tolerance bores and, instead of machining, we can put them on the EDM machines and achieve tolerances better than ±5 µm with excellent surface finishes.”

From a productivity standpoint, the Mitsubishi MV1200R and MV2400R are running across the company’s two-shift pattern, with many jobs set up to run unmanned overnight or at the weekends.

Three key aspects make ONA’s new IRIS its most advanced EDM machine to date: an unprecedented integration of digital tools, a powerful graphics engine together with easy-to-use touchscreen, and a 100% digital, configurable and programmable generator.

The ONA IRIS offers digital tools that include improvements in terms of data download and transfer, external connections, security, integration with other software, and remote process management. In addition, the IRIS can integrate ONA’s Security Pack, a system that allows for the creation of an administrator, the configuration of different profiles, the limiting of file modification or deletion, as well as the blocking of external access.

Thanks to its graphics engine, users will be able to simulate processes before executing them, verify results, and change the configuration as necessary, all while the machine is in full production of another job. Its large touchscreen also allows for use in tablet mode and, together with a user-friendly interface and digital JOBS manager, ONA says that customers can expect a significantly improved project management experience.

ONA reveals that IRIS has the market’s first CNC that visualises the real execution of a die-sinking job in 3D. The ONA IRIS CNC also displays 3D models of parts and electrodes in a wide variety of file formats, including STEP, IGES, VRML and BREP.

Thanks to the digital JOBS manager with user-friendly interface, operators will be able to manage everything from simple programs to complete manufacturing orders. All the information necessary to process an EDM job can be contained in the JOB, including its priority in the JOBS queue. On the other hand, the large touchscreen and the ability to use it in tablet mode will facilitate the management work of any task.
