Product Introduction
In ES-8A EDM operation, the X and Y axis of the EDM machine is not move during the whole machining process, whereas the Z axis is keep moving up and down, the most important mission of the EDM machining is control the depth of the machining precisely.
Since the Z axis is keep moving up and down during the whole machining process, it is very difficult for the operator to decide the depth of electrode, ES-8A EDM provides specialized EDM operating display to show the deepest position that the electrode have ever reached and the target machining depth. It greatly help the operator to understand and control the EDM machining process.
ES-8A EDM provides relay output to stop the EDM machine automatically once the electrode reached the target machining depth.
Relay output circuit for ES-8A EDM
Because most EDM machine are equipped with big capacitors in their power circuit, therefore, they normally not affected by short power black out which may be caused by storming weather or the voltage drop triggered by the start up of a big machine in the same power line or etc. However, DRO are not equipped with big capacitor and hence much more sensitive to power failure and will reset after power failure. In the case if the EDM machine won't reset but the DRO reset during EDM machining operation, the DRO will lost the Z axis electrode position during the reset , it will cause a mistaken machining.
To avoid such problem, ES-8A EDM using the opposite output design. In case the ES-8A EDM lost power or being reset, it's output always in "Activate" state to stop and lock the EDM machine to avoid any possible mistaken machining.
Connecting Pin Configuration
Normally "Open", Activated "Close" : Pin 6 & 7;
Normally "Close", Activated "Open" : Pin 6 & 8
EMC Testing equipment
To Make sure all Easson DRO products can be pass the EMC standard specification, we have a complete set of EMC test ESD immunity tester.
