ABSTRACT:
An improved wire-electrode support and guidance assembly for electrical machining comprise a first wheel rotatable about a first axis and formed along its periphery with a continuous annular recess of a uniform depth and adapted to receive and retain therein a continuous wire electrode which is axially advanced and transported from a supply reel to a collection reel through the region of a workpiece. The assembly includes a second wheel rotatable about a second axis parallel to the aforesaid first axis and having a flange of a profile substantially complementary to that of the aforesaid recess, and includes means for urging the first and second axes relatively towards each other to drive the flange of the second wheel into a mating engagement with the recess of the first wheel so that the wire electrode when passed through the recess is squeezed surfaces of the recess and the flange.
