ONA Introduces NX Series of Die-Sinking Erosion Machines

The NX series of die-sinking erosion machines from ONA Electro-Erosion S.A. consists of 44 standard configurations. The smallest is the ONA NX3, with X-Y-Z travel of 15.8 x 11.8 x 11.8 inches. The largest model is the TX10, whose travels in those axes are 119, 59 and 39.4 inches, respectively, and which features two heads commanded by two independent CNC generators, allowing two cavities to be eroded simultaneously and independently in big workpieces with a mass as great as 44,000 pounds.

The new high speed ONA Standard NX4C die-sinking machine is the latest in the series and features a rise-and-fall work tank. The ONA-S64 CNC has an open control and supervision protocol, and its design that facilitates automation of all sorts of applications. The NX4C has an X-Y-Z travel capability of 23.6 x 15.8 x 15.8 inches. Its fixed table design allows loading of workpieces up to 3,300 pounds. The NX4C features a Z-axis speed of 590 inches per minute and an acceleration of 1.0 G which is useful in deep no-flush rib cuts and can decrease the time by as much as 35% on certain simple ribs. The Z-axis maximum weight capacity is 440 pounds which adds versatility while providing speed and acceleration, the company said.

The entire ONA Modular series die-sinking machines NX7, NX8, NX10, TX8 and TX10 have also been improved, the company said. The "T" in the series designates that the machines are the twin headed versions. The Z-axis speeds for the current machines are now nearly three times faster and with double the acceleration of last year's models. All while maintaining the maximum weight capacity of 440 pounds on the Z-axis ram.

All models in the ONA NX series come equipped with micro fine circuitry for achieving surface finishes to 0 VDI (0.10 m Ra) and over 10,000 hours long-life filtration system without consumable cartridges.
