Abstract

An electrical machining device is provided for machining a surface of a workpiece. The electrical machining device includes a nozzle connectable to an electrolyte reservoir, the nozzle configured to dispense electrolyte towards a surface of a workpiece, in use, and an electrolyte flow path for conveying electrolyte from an electrolyte reservoir to the nozzle. The electrolyte flow path has a gas inlet therealong and the electrical machining device is configured to inject a gas into electrolyte flowing along the electrolyte flow path via the gas inlet, in use, so as to form gas bubbles in said electrolyte.

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.
