Our best estimate for a sinker edm (ram edm) in this class — not a quote from ONA Electroerosion. Configuration moves it a long way.

Overview

The ONA NX 10 is a die-sinking EDM listed with a 128 A peak generator on mid-size travels: 450 mm in X, 350 mm in Y and 400 mm in Z, over a 700 mm × 500 mm table. Workpieces can weigh up to 700 kg and the machine itself approx. 5,500 kg.

That is a lot of current for the envelope. A 128 A peak rating, on what the table calls an advanced digital generator, gives room to rough with broad electrodes, so on medium mould cavities the limit is more likely to be flushing than available current. The other end of the range is listed too: Ra 0.1 µm in ultra-fine finish mode.

Two rows concern process stability and shop integration. The dielectric is oil with temperature control, which limits thermal drift over a long unattended burn. The control is ONA-CNC with Industry 4.0 connectivity, naming OPC-UA and MTConnect, so machine status can be read by a monitoring system that speaks either protocol.

The listed figures leave out the electrode weight limit, tank size and positioning accuracy. Ask for those, and check the generator rating on the machine's own plate, before sizing a job to this machine.

Strengths & Limitations

Strengths

128 A peak advanced digital generator on a machine with 450 mm of X, 350 mm of Y and 400 mm of Z
Ra 0.1 µm listed in ultra-fine finish mode
Dielectric oil with temperature control
ONA-CNC with Industry 4.0 connectivity over OPC-UA and MTConnect
700 kg workpiece limit on a 700 mm × 500 mm table

Limitations

No electrode weight limit is listed
Positioning accuracy and tank dimensions are missing from the listed figures
Approx. 5,500 kg calls for a floor-loading check before installation
Y travel of 350 mm leaves part of the 500 mm table depth out of reach

Best For

Medium mould cavities roughed with broad electrodes at up to 128 A Ultra-fine finishing to Ra 0.1 µm Shops collecting machine data over OPC-UA or MTConnect Mould and die blocks weighing up to 700 kg

Frequently Asked Questions

01 How powerful is the generator on the ONA NX 10?

The generator row reads 128 A peak, described as an advanced digital generator. A separate power pack row in the same table shows a lower current figure, so confirm the rating on the generator plate of the machine you are considering before planning roughing work around it.

02 Does the NX 10 connect to shop monitoring systems?

The control is listed as ONA-CNC with Industry 4.0 connectivity, and names OPC-UA and MTConnect. A monitoring or MES system that reads either protocol should be able to collect status from the machine; which data items are exposed is not listed.

03 What are the travels, table size and load of the NX 10?

Listed travels are 450 mm in X, 350 mm in Y and 400 mm in Z. The table is 700 mm × 500 mm and the workpiece limit is 700 kg. The machine weighs approx. 5,500 kg. No electrode weight limit or tank size is given.

04 What surface finish is listed for the NX 10?

Ra 0.1 µm in ultra-fine finish mode. Reaching a figure like that takes a dedicated finishing technology, small burn areas and stable dielectric temperature, and the table does list the dielectric as oil with temperature control.
