Small Punch Tool

<< < (2/3) > >>

BillTodd:
The most accurate machine we had at work was a swiss made Agie (?)  it could handle 100um wire  . They are bloody expensive to run but capable of astonishing accuracy.

The wire edm electrolyte was deionised water from a massive (as big as the edm) filter units.

 The sparkers , die sinkers, used an oil similar to paraffin, with automatic fire suppression systems (that would occasionally go off without prompting).

Yes , the finish is fine but granular, it would need lapping to a cutting edge.

We had an Agiemaspark (not sure how it's spelt) die sinker. As you say it used a paraffin like coolant. It probably went for £100 or so when our toolroom closed! A very useful machine.

My Eurospark H425 die sinker is almost identical to the Agiemaspark, in fact many were badge engineered. Here's an ancient thread describing mine:

philf:
Andrew - haven't you got a wire eroder as well?

awemawson:
Yes Phil, there's a wee little write up about it here on the forum:
