TOOL FOR MAKING MULTISTAGE DISC GROOVES BY A RE-MILLING METHOD, A UNIT AND AN ELECTROCHEMICAL PROCESSING MACHINE CONTAINING SAID TOOL, AND A METHOD USING SAID TOOL Russian patent published in 2020 - IPC B23H3/04 B23H9/10 

FIELD: electrochemistry.

SUBSTANCE: invention relates to electrochemical processing, which provides for making slots in multistage disk. Disclosed is tool (10) for electrochemically performing grooves in multistep disk (1), comprising at least first and second rings (20), each of which is located coaxially around disk axis and is configured to perform function of cathode for processing corresponding to one of two stages of different diameter of disc (1). Each ring has an inner periphery comprising a plurality of radial working protrusions (22) having a shape corresponding to the shape of the slots to be made, wherein first and second rings (20) are rigidly attached to each other. Also disclosed is a method for electrochemical execution of multistage disc grooves by electrochemical treatment using said tool.

EFFECT: invention provides relatively simple performance of different stages of multistage disc in a short time.
