The DC pulse generator of your machine has to ( 1) ensure an adequate supply of voltage/current to initiate the spark discharge and later to maintain it and ( 2) to vary the intensity of the discharge current and duration of the discharge as per needs. The electrical panel box of your machine has a voltmeter, ammeter, DC pulse generator, and power supply to the dielectric pump, servo motor, etc. The platen and the fixture of your machine are suitably insulated since the electrode and the workpiece are connected to the DC electric source.Ī small gap (approximately 0.25 millimeters, exact value depends on the work-piece material and other parameters) is maintained between the electrode and the work-piece of your Sinker-EDM, and this gap is called spark-gap. You must mount the workpiece on a fixture (insulated) and clamp the fixture to the table using T-slots. The dielectric tank in your machine has a level controller to ensure no overflow of dielectric fluid. The dielectric tank of your machine is mounted on the machine table and moves along with it the front of the tank (door) can be opened during the setting of the electrode (tool) and the workpiece. The sinker-EDM machine table can be moved in the X and Y axis for locating the workpiece with reference to the electrode (tool) the electrode-head moves vertically up and down on the column and carries the platen (insulated) mounted with the electrode. General arrangement of a Die Sinker-EDM Machine How Sinker-EDM worksĪ Sinker-EDM machine has the standard features required for the EDM process like Table, Electrode-head mounted on the ram, DC Pulse Generator, Servo motor, or CNC System for the vertical movement of the electrode (Z-axis) and dielectric fluid system. Your Sinker-EDM machine is generally used for forming blind cavities since open cavities can be machined comparatively faster and economical by Wire-EDM Machine. The machine you use for Die Sinking is known by many names like Sinker-EDM, Ram EDM, and plunge EDM. Your EDM process literally sinks the profile of the electrode (tool) onto the work-piece surface and this can be the reason for the name ‘ Die Sinking’. The profile of the electrode of your machine is duplicated onto the work-piece surface by continuous recurring electric spark discharges, applied in pulses. You use Die Sinking EDM ( Electrical Discharge Machining) process to create intricate and complicated cavities in the workpiece the electrode (tool) and the workpiece are connected to DC electric source and submerged in a continuously flowing dielectric fluid.
