ONA not only manufactures a wide range of standard-size EDM machines, it also specialises in the design and manufacture of large models such as the AV130, which has a 10 tonne load capacity as standard (expandable to 25 tonne).

According toONA, the AV130 brings great ideas to life, transforming large-scale projects into simple solutions. Of particular note, the ONA AV130 automatically threads of all types of wires and offers a cutting capacity of up to 800 mm in height. The X-axis travel is 2000 mm, with 1000 or 1300 mm in the Y axis. U/V axis travel is 500 x 500 mm, while the maximum taper angle is 30°.

The company says that the AV130’s high cutting speeds equate to a 30% time saving, complemented by minimum maintenance costs and greater autonomy with wire coils weighting up to 45 kg.

ONA’s versatile modular design of its large wire EDM machines allows more than 20 combinations, providing the ability to work with the largest parts on the market. The machineprovidesusers with speed, autonomy, strength and precision, alongsidegreater execution power.

The company says there are many benefits associated with its AV technology. For instance, the numerical control, designed on the concept of usability, has a 23” touch interface, intuitive and visually friendly menus, applications represented by icons, andreal-time information forgreater control of the EDM process. Furthermore, the new interface displays the workpiece in 3D and allows the operator to rotate and move it according to requirements with a simple tap.

GF Machining Solutions has introduced a new range of wire EDM machines. The AgieCharmilles CUT F series comprises two models (CUT F 350 and CUT F 600), each equipped with the company’s proprietary Uniqua control, ISPS intelligent spark protection system, iWire intelligent functions and RFID smart wire system. Furthermore, at the heart of every machine is the proven high-end IPG-DPS generator.

According to GFMS, CUT F machines deliver improved performance and optimised precision. The range sits in-between the company’s established CUT E and CUT P series’ of wire EDM machines and features the tried and tested SparkTrack technology platform.

The new C-frame machines feature an enhanced design that improves thermal stability and vibration control, resulting in higher part accuracies and superior surface finishes, reports the company. Specific features include axis optical encoders (cooled via the work tank and dielectric fluid) and high-accuracy, high-grade ballscrews that improve positional accuracies.

CUT F machines come with an intuitive iHMI featuring a 19” vertical touchscreen, full keyboard and a mouse. The Uniqua platform interface supports offline and at-the-machine programming, and facilitates sequential and object-oriented programming. The control hasa powerful graphic tool with an integrated CAM system and is compatible with all major CADCAM programs.

Of particular note, the iWire function automatically identifies and adapts the wire speed to changing erosion height conditions during the EDM process and, by sodoing, eliminates wire breakage while reducing overall wire consumption per job – in some instances by as much as 29%.iWire technology works in tandem with ISPS, both of which are accessible from the Uniqua control.

For manufacturers that demand the epitome of precision, component quality and production efficiency, Sodick Europe says it has introduced its new VN series of linear motor-driven wire EDM machines. Presented as a high-quality enhanced range of standard EDM machines, the new arrival offers the added advantage of reduced power consumption and operational costs.

Available in two variants, the new VN400Q and the VN600Q can deliver a 20% decrease in power consumption when compared with standard models. With up to 70% of wire EDM energy consumption used by the dielectric treatment system, the Sodick VN series overcomes this issue with a new fluid control circuit that reduces the energy needed to drive the dielectric processing pump. Utilising an inverter to control the vertical flushing flow rate during machiningdelivers a 20% reduction in power consumption during machine standby.

As well as reducing power consumption, the newly developed energy-saving pump is integrated into the dielectric tank and, along with the LN3W/LP3W power supply unit, the Sodick VN series significantly improves nozzle flushing performance to amplify open cutting speeds by up to 15%. In addition, an intelligent monitoring circuit oversees the vertical flushing flow rate to provide further optimisation of the pump drive energy for flushing.

Also contributing to the efficiency of the Sodick VN series is the linear motor drive system with linear scales. Providing precise high-speed axis motion that is wear-free, it is possible to maintain extremely responsive speed, precision and repeatability for years to come. This performance sees a further enhancement with the latest K-SMC motion controller that governs axis movements and tracks spark-gap adjustments.
