The servo module is design to allow it to be removed easily and quickly from the Texturing Head Assembly – regardless of its position.

Each servo can be extended or retract, to allow the operator to change the electrodes quickly and easily.

The Servo Module consists of a Servomotor, precision ballscrew, Electrode Holder and Hot Rod.

The Servomotor and precision ballscrew provides the electrode movement. The Servomotor is controlled by the EDT Servo control cards.

The Electrode holder provides ‘electrical isolation’ from the EDT Power and it is used to hold the electrode.

The Hot Rod supplies the EDT Power and Dielectric oil to the Electrode.

The Dielectric Oil is supplied to each side of the manifold. The Dielectric Manifold is positioned on the roll surface – a pool of Dielectric is form around each electrode. The Electrode is submerged in Dielectric fluid.

The Dielectric Manifold ensures there is adequate Dielectric around each electrode. There are a number of holes, around each electrode, which provides dielectric oil to the tip of each electrode.

The brush material allows the dielectric oil to creates a pool of oil around each electrode – submerging the electrode in dielectric oil. The Electrode passes through the manifold.

Dielectric oil is supplied to the texturing gap via the Dielectric Delivery Manifolds, and the oil which flows through the centre of the electrode (centre flush dielectric).

1. Inside the Texturing Head Assembly are a number of electrically operated solenoid valves, which are used to control the centre flush dielectric. All the solenoid-operated valves are supplied with dielectric from a common manifold. This assures that all the electrodes in the Texturing Head Assembly are operating at the same dielectric fluid pressure. Each solenoid valve can be individually operated.

2. The SMS Smart EDT system uses a Dielectric Delivery Manifold to ensure there is a continuous pool of dielectric around each electrode. Each manifold supplies the dielectric for one row of electrodes. Each electrode is supplied with its own dielectric fluid via eight (8) holes surrounding the electrode. A brush material is also used to hold the dielectric around each electrode.

3. The dielectric fluid flow, temperature and pressure are monitored by sensors mounted on the Texturing Head Assembly and relayed back to the CNC controller. If any of the sensors cause a fault condition, texturing stops and a message is displays on the CNC controller.
