DEVICE FOR HOLDING ONE OR MORE ELECTRODES DURING ELECTROEROSIVE MECHANICAL PROCESSING AND METHOD FOR MANUFACTURING THE SPECIFIED DEVICE Russian patent published in 2022 - IPC B23H7/26 B23H9/10 B23H9/14 C04B35/119 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the manufacture of a device for holding one or more electrodes during electroerosive processing. Device (39) contains case (41) with straight-line part (43a), in which there is at least one first channel (45) for conducting at least one electrode (46). The case additionally has curved part (43b) made as a single whole, in which there is at least one second curved channel (47) for supplying dielectric fluid, and in which there is a curved extension section of the specified at least one first channel. The curved extension section and the second curved channel are made of ceramics, and the value of arithmetic mean roughness (Ra) of the inner surface in them is Ra < 2 mcm.

EFFECT: device is provided, the geometry of which is adapted by shape and size for access to hard-to-reach areas of electroerosive processing, capable of withstanding multiple long-term mechanical processing, as well as the possibility of manufacturing, if needed, a specific device for each case of processing and the possibility of automizing the device operation, in particular for performing directional drilling.
