Abstract:
An electrode positioner for electric-discharge texturing apparatus for performing texturing of a workpiece surface, comprising:an elongated housing of a generally tubular construction having first and second ends;a slide mounted by the housing for movement along a slide axis extending along the housing, the slide having a servo head supported thereby at the first end of the housing, and the servo head including an electrode holder for holding an electrode used in the electric-discharge texturing of the workpiece surface;a servo actuator mounted by the housing adjacent the second end of the housing and operable to move the slide and the servo head with the electrode supported thereby along the slide axis toward and away from the workpiece surface; andan elongated connector located externally of the housing and extending from the servo head at the first end of the housing to the second end of the housing in a parallel relationship to the slide axis, the elongated connector having an internal passage for carrying dielectric fluid to the servo head at the first end of the housing from a dielectric fluid supply adjacent the second end of the housing, and the elongated connector having an electrical connection to the servo head at the first end of the housing and an electrical connection for connecting to an electrical power supply adjacent the second end of the housing to supply electrical power to the electrode supported by the electrode holder on the servo head.
