O/T System 3R Pro's and Con's

[lou]

Hi all,

 

I have been managing the CNC area for a while now. Now upper management threw the CNC EDM in my department now and I have to start using System 3R fixtures for everything.

 

I am just wondering what are the Pro's and Con's in using the 3R automation? I would like to here some success stories and not so successful stories.

 

Thanks in advance for all you input!!

I used the 3R system before for electrodes,its great.

 

We cut the electrode on its 3R system on the machine then straight into the EDM.

 

We used copper electrodes.

We had a 3R system permantly set on the NC machine set as G59 so any Electrode program was made around that so you only had to set the different Z values.

I worked at a place where we bought a couple of their pieces for sinker and wire and then just made our own from then on. Anything modular is the way to go. Good system. They have a indexable, magnetic holding system for electrodes that is world class.

The system 3R macro system is a great system. Great repeatablility and indexing (90 degree).

We use Hirschman fixtures for our wire. They also work quite well too. Check them out.

We use Erowa instead of 3R .

A bit expensive but supergood ,simple and accurate .

It is indexable and I made a lot of special holders that enlarge a lot it`s versatility .

The electrodes from mill ,lathe or wireedm go

to the edm with no need to additional setup .

Great thing for speeding up production
