A lot of people
say it's impossible to be fully up to date on developments in technology.
Buy a new computer, they say, and in three or four years it's a
museum piece. With a certain disquiet we do what we can with the
limited capacity of a hard disc, or we suffer the slowness of a
dated computer.
But at ONA Electroerosión
we're winning. We wanted to see our improvement, especially where
technology is concerned, expressed as impartially as possible. So
we engaged two Portuguese clients and two Spanish clients to help
us produce the figures. We asked them to carry out the same job
with two sister machines, one of them old and the other up to date.
The result was
spectacular. Work time, electrode wear, and final surface finish
had been reduced by an average of 50%. The examples are sufficient
to convey the picture. ONA Electroerosión: Cum Laude.
