Therefore, the combination of the rotary adjustment table 1 and the horizontal adjustment table 2 allows the graphite electrode 5 to be finely adjusted at multiple angles when performing EDM on the product 6. This enables more accurate positioning when machining products with deep curved surfaces, thereby ensuring the quality and dimensional accuracy of the product machining.
[0036] The horizontal adjustment platform 2 includes a horizontal adjustment base 201, which includes a horizontal base plate 2011 and an adjustment ball 2012.

When the graphite electrode 5 is replaced, if the seat limiting block 501 and the seat clamping block 502 of the graphite electrode 5 are not changed in size, the graphite electrode 5 can be separated from the quick clamping assembly 4.
[0041] If the seat limiting block 501 and the seat clamping block 502 of the graphite electrode 5 are changed in size, the fixing bolt 304 can be loosened, the quick clamping assembly 4 can be separated from the connecting assembly 3, and the graphite electrode 5 can be quickly removed after the quick clamping assembly 4 is removed, so that the efficiency of changing the model is improved, and the graphite electrode mechanism can adapt to the clamping of graphite electrodes 5 of various shapes and sizes, and the equipment is convenient for processing products 6.
