No.2（1999）7.Nonflammable fiuid with the EDM of electroconductive ceramic and metal

We investigated non-flammable fluid of the EDM(electrical discharge machining)of TiB₂,as electro-conductive ceramics and SKS3. The results are as follows:

1. The working speed of non-flammable fluid and water were faster than that of Oil and TiB₂.
2. The electrode wear ratio of non-flammable fluid and water were smaller than of Oil and TiB₂.
3. There was no difference in the average roughness(Ra) of all fluid and TiB₂.
4. SKS3 did not make good use of non-flammable fluid and water all this condition.
