ONA KE 350 and KE 450: the least large in the "KE" series of big ONA machines


At 22nd BIEMH of Bilbao, ONA shows two new models of the revolutionay range of machines ONA KE.

Some of the features of these models

  • All the ONA KE series thanks to its new CNC with Expert Erosion System offer the maximum productivity, ensuring long machining times without any operator intervention.
  • New "Automatic strategy": a simple, effective tool for programming at the highest level.
  • New, quicker, friendlier CNC for enhancing human-machine interface
  • Fixed bedframe, so that the machines will accommodate very heavy workpieces, from 3.000 kg (ONA KE 350 unit) up to 10.000 kg (ONA KE 1000 unit).
  • Wide taper ungles. ±30º tapered cutting along the entire X-Y traverse to cut up to a height of 400 mm on the KE 1000 model, 28º/400 mm on the KE 500.
  • Built in is a new automatic threading system that can handle a large variety of diameters and wire types (ONA patent).
  • Height of 600 mm in the immersion cutting mode on the KE 1000 model. 400 mm on the KE 500, KE 450 and KE 350 models.
  • Filter with zero maintenance cost (ONA patent).

Ram EDM new developments

New ONA CS and HS series

Proven advances in performance, precision, and surface quality

On the basis of the widely known ONA TECHNO models, ONA has produced the new CS and HS series.

The improved design where mechanics and electronics are concerned means that machines in the CS and HS series are notably more efficient, especially in the case of jobs that involve very difficult flushing. These improvements have been possible thanks to a new high-speed pulse technology, which is based on faster head action and servomotor control. Thanks to the perfect combination of this technology with the advanced generator of the machine and its Erosion Expert System, becomes feasible obtaining deeper machining and flushing is no longer a problem. Also, precision is higher.

  
 

ONA HS 700 Model

Comparative of performances:

 

 

 

 

  
   


Electrode: graphite rib
Width: 1 mm
Length: 60 mm
Workpiece: steel
Final obtained rugosity: 22 VDI - Ra 1,26 µm
Surface finish: 22 VDI - Ra 1,26 µm


New features incorporated to the CNC of the ONA CS and HS series:

  • The CNC incorporates new technology tables specifically for the machining of grooves. Very deep grooves can be machined (deeper than 100 mm), with the highest quality and precision guaranteed.
  • More homogeneous finish on large surface areas. The CNC belonging to units in the CS and HS ranges incorporates new technology tables specifically intended for an excellent, homogeneous surface finish where the working area is large.
  • New submarine injection (subgate) function.
