Abstract
An electrode guide assembly for an EDM process includes a guide tube having a first end and a second end, a fluid feed portion, a fluid return portion, and an electrode. The guide tube has a set of at least two supporting protrusions, with the protrusions projecting radially inwardly from an inner diametral surface of the guide tube. The electrode is slidably accommodated within the guide tube, with an outer diametral surface of the electrode abutting against the set of supporting protrusions. The first end of the guide tube is in fluid communication with the second end of the guide tube to thereby provide a fluid feed channel, and the second end of the guide tube is in fluid communication with the first end of the guide tube to thereby provide a fluid return channel.

An electrode guide assembly for an EDM process, the assembly comprising:
- a guide tube having a first end and a second end;
- and
- an electrode,
- the guide tube having a set of at least two supporting protrusions, the protrusions projecting radially inwardly from an inner diametral surface of the guide tube, the electrode being slidably accommodated within the guide tube, with an outer diametral surface of the electrode abutting against the set of supporting protrusions,
- the first end of the guide tube being in fluid communication with the second end of the guide tube to thereby define a fluid feed channel, the second end of the guide tube being in fluid communication with the first end of the guide tube to thereby define a fluid return channel.
