IPC: B24B1/00
Filed: 1994-10-26
Abstract: PURPOSE: To execute extremely high ultraprecision grinding by irradiating the surface of several kinds of solid with a gas cluster ion beam. CONSTITUTION: Gaseous CO2 fed from a gas cylinder 3 is jetted from a nozzle 4 in a source chamber 1 at a supersonic speed and is adiabatically expanded to form gas clusters.
