Dependence of the surface roughness of small apertures on type of the working environment and modes of electroerosive processing

The questions connected with maintenance the requirements, shown to the quality of processed surface of small apertures in preforms from steel 12Х18Н10Т are considered, allowing to raise competitiveness of products. Dependence of the surface roughness of small apertures received by electroerosive processing, on the interelectrode environment (water and kerosene), energy and frequency of impulses is established.
