  • Publication number: 20240001468
    Abstract: A nozzle for an electrochemical machining device. The nozzle defining a body with first and second releasably attachable body portions forming an electrolyte cavity therebetween, when the first and second body portions are attached. The body includes an inlet port upstream of the cavity, and an outlet port for dispensing a jet of electrolyte towards a surface of a workpiece, in use, where a flow path is defined from the inlet port through the cavity to the outlet port.

  • Publication number: 20230065692
    Abstract: An electrolyte solution is provided for an electrochemical machining process. The electrolyte solution includes a substantially water free ionic solvent, an ionisable material in the form of an inorganic salt; and a viscosity modifier. The electrolyte has a viscosity in the range of 1 to 50 mPa·s at 20° C.

  • Patent number: 11511361
    Abstract: An electro-discharge machining (EDM) device that includes a housing, an erosion electrode, a ground electrode, and a dielectric inlet. The housing is configured to be positioned on a surface of a workpiece and proximal to a fastener to be eroded. The planar erosion electrode is positioned at least partially within the housing, with the erosion electrode being movable relative to the housing in a first axis. The first axis is substantially normal to a longitudinal axis of the fastener. The ground electrode is conductively connected to the fastener. The dielectric inlet is configured to deliver a dielectric fluid to a region between the erosion electrode and the fastener.
