The NX4C is the latest in the company’s NX series of ram EDM machines. Featuring a rise-and-fall tank, the NX4C offers XYZ travels of 23.6” x 15.8” x 15.8” and has a fixed bed that allows the machine to accommodate workpieces as heavy as 3,300 pounds. Its open-architecture S64 CNC, which allows the machine to be connected with robots, palletization systems and plant controllers, has been upgraded. The CNC ensures effective movement and workpiece erosion in simultaneous-six-axis operation while its a-Space function enables any programmable CNC erosion function to be carried out in any spatial direction, the company says. The S64 CNC also includes an extensive set of automatic measurement cycles that simplify the tasks of completing the workpiece and electrode in the machine.
According to the company, all models in the ONA NX series come equipped with “microfine” circuitry for achieving surface finishes to 0.10 µm Ra as well as a long-life filtration system without consumable cartridges. The NX series of ram EDM machines consists of 44 standard configurations. The smallest model is the NX3 with XYZ travels of 15.8” x 11.8” x 11.8” and the largest is the TX10 with XYZ travels of 119” x 59” x 39.4”. The TX10 model also features two heads commanded by two independent CNC generators, allowing two cavities to be eroded simultaneously and independently in a workpiece as heavy as 44,000 lbs.
