How to fix HPEDM EROWA sinker EDM machine electrode

A good EROWA  EDM electrode holder combination, not only to use advanced machine production, but also skilled workers to assemble. Once the assembly is not good, it will seriously affect the positioning accuracy function of the product, which will lead to a decline in the yield. Therefore, the installation of the EROWA electrode holder assembly is notoriously “troublesome” and requires a lot. But it is also the “trouble” EROWA fixture positioning accuracy is so high!

Firstly, the electrode holder assembly is composed of several parts: a centering plate and an electrode holder. The centering plate  includes an M5 screw, a hexagonal nail, an inside piece, and a outside piece.

  • 1. Before installation, the assembler first checks the above parts. The contents of the inspection include whether the parts are damaged or not. The error of each hex nail is not within the required range and the parts are clean and flawless.
  • Check that the parts are correct before starting the installation. The first step of the installation is alignment. Firstly, the outside plate has the HPEDM logo and the direction of the  HPEDM logo marked on the electrode holder; the centering plate has a blistering base, smooth and engraved  was be on outside
  • Install the hex nail. First install the M5 screws. Note that the M5 screws and the hexagonal nails are installed in the same direction. Install the mounted M5 screws on the electrode holder.
  • It is not enough to manually install the M5 screw on the electrode holder. Also use the special torque wrench to adjust the position to 5kg (5N).

The M5 screw receives the proximity positioning surface, and then tightens it with a wrench until the wrench vibrates (ie, 5N locking force).

  1. Finally,  Adjust the electrode holder . Place the assembly on a flat table and check

that the four hex nails are flat. If unevenness occurs, adjust the balance with a normal wrench and then test on the test instrument. The precision is required to be ±0.002 mm.

Advantages of  Graphite electrode processing

 

Graphite electrodes are used for mold making and are processed by EDM  die sinking .

The increasing complexity of die geometries and the diversification of product applications have led to higher and higher demands on the accuracy of spark discharge. Graphite electrodes have the advantages of easier processing, higher discharge machining efficiency, and lower graphite loss. Therefore, EROWA fixtures are the most suitable, and some spark machine customers have abandoned copper electrodes and switched to graphite electrodes. In addition, some special-shaped electrodes cannot be made of copper, but graphite is easier to form, and the copper electrodes are heavier and are not suitable for processing large electrodes. These factors have caused partial spark machine customers to use graphite electrodes.

For the processing of the mold electrode, accuracy is the primary condition, graphite electrode processing is more complex, it is recommended to use flexible positioning fixture, HPEDM professional manufacturing flexible positioning fixture, repeatability  is 0.002mm. Products can be compatible with EROWA, 3R fixture system perfectly.

How to Maintain CNC EDM workholding toolgrinding EROWA chuck system

HP CNC EDM tool system Most workholding tool systems are made of hard and corrosion-resistant steel. When using on-line cutting machines, in order to maintain the corrosion resistance of the products.

Please do as the following needs:

  1. Due to the conduction of the current, ensure a stable contact between guide rail and

workpiece

  1. It’s necessary that has Solid contact with the machine table ; this will be ensured by suitable cable connections
  2. Pat attention to the conductivity of water. Incorrect conduction performance will not only affect the processing performance of your wire-cutting machine, but will also destroy the corrosion resistance of the fixture. Please confirm that the conduction value is between 5mS and 20mS. The pH of the dielectric should not be lower than PH 5.5, ideally up to PH7

 

  1. In order to maintain the working performance and corrosion resistance of CNC EDM  fixtures, it is necessary to remove the discharge residue on the components of the fixture once a week.
  2. If the fixture is used for multi-shift machining, the cleaning and maintenance work of the fixture shall be performed on the wire gap of the wire cutting machine.

Please clean, dry and maintain the fixture before storage so that there will be no problem when it use
