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).
- 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.
