Servo Voltage Stabilizer for EDM Machines Protection

Electrical Discharge Machining (EDM), also known as spark machining, die sinking, spark eroding, burning, wire burning/wire erosion etc. This is a manufacturing process whereby a desired shape is obtained by using electrical discharges. In this process material get removed from the workpiece by a series of rapidly recurring current discharges between two electrodes, separated by a dielectric liquid. It is a subject to electric voltage and due to voltage fluctuation; machine would not give a desired performance. Hence, Servo voltage stabilizer gives complete stable output supply in case of unbalanced Voltage under any severe condition. It is available to suit the input voltage variations to protect EDM machines.

Before we discuss more about the benefits of the servo stabilizer with EDM machine, let’s talk about main problem area of the EDM machine accrued due to the voltage fluctuation. When the voltage between the two electrodes is increased, the intensity of the electric field in the volume between the electrodes becomes greater than the strength of the dielectric which breaks down, allowing current to flow between the two electrodes. This phenomenon is the same as the breakdown of a capacitor/condenser. As a result, material would be removed from the electrodes. Therefore these machines require a grounding electrode conductor for electrical power system to building the grounding electrode system.

These grounding electrode conductor and electrode system are meant to provide a low-impedance path to earth for electrical fault currents and reference in building electrical system for the surrounding areas.

servo stabilizer with EDM Machine

Usually, an EDM machine’s signal reference is a common wire of its computer logic power supply connected to ground plates. These ground plates are bonded to the machine’s enclosure, equipment grounding conductor/conduit and to the building grounding electrode system. So the equipment ground establishes the local signal reference within the EDM machines.

EDM machines contained in a cabinet with good grounding, bonding that may be relatively immune to noise or stray currents. Therefore, these machines with data links may be quite susceptible to stray currents. It’s just because the other area of the factory would also have a signal reference ground. These different reference ground points may increase an EDM machine’s sensitivity to voltage fluctuation. That is the main reason for the malfunctioning of the EDM machines which may not be noticed by the responsible person or by the owner of a company.

Servo voltage stabilizer provides optimal solution for any problem related to EDM Machine. It would not only save the money but it would also save their priceless time of an EDM machine owner.
Servo stabilizer is used with EDM machines to protect it from unbalanced voltage. As EDM machines are costly & key components of any manufacturing company. If there is a voltage fluctuate these machine may malfunction because EDM machine comprises of the several micro parts that acts as the controller unit. These machines are available with different types such as: EDM Measuring Machine, Small Hole EDM and wire EDM but every machine requires Servo Star stabilizer for the better results. Let’s have a look on its benefits & features.

Features of a Servo Stabilizer for EDM Machine:

1. Automatic & manual operation
2. Based with low and high voltage limits
3. EDM can be accurate to +/-1%
4. Correction rate with 20 to 90v/as
5. Response timing – 10 milliseconds
6. High- technique grade component reliable for special sensing
7. Consistent performance & Authentic
8. Ensures constant Output Voltage even with distorted input from DG set
9. No noise by the system because of isolated servo drive
10. Highest efficiency up to 98.%
11. Insures trouble free operation
12. Built-in digital metering for measurement of voltage

Benefits of Servo Stabilizer with EDM Machines:

1.   Instantly steady & accurate the voltage fluctuation
2.  Surge suppression, voltage cut-off, Low & High Voltage overload
3.  Protection by MCB, audio-visual alarms, Oil filling exclusive, Single phase prevention, bypass of servo with main Line
4.  Constant output voltage and despite load current variations
5.  Balanced output voltage, irrespective of input imbalance
6.  Energy saving with 98% efficiency
7.  Reduces heating and increases the life of EDM machines

Therefore, Servo Voltage Stabilizer is best suited for EDM Machines automation and computer controlled systems. EDM machines cannot sustain voltage fluctuation for the time. Servo Star Stabilizer is a perfect solution, if there is line voltage correction speed requirement is slow like EDM Machines, AC drives and other computer controlled machines.

When we talk about the industrial application Servo Voltage Stabilizer will always be a better option, to eliminate break downs and to ensure better functioning of EDM machines such as EDM Measuring Machine, Small Hole EDM and other important appliances of any company.
