Abstract
Systems and methods for polishing one or more metal surfaces of one or more unattached parts by projecting a beam of electrically active solid particles capable of ionic transport onto the one or more metal surface while the one or more unattached parts tumble inside a rotating drum.
Claims20
A system for polishing one or more metal surfaces of one or more unattached parts by projecting a beam of electrically active solid particles capable of ionic transport onto the one or more metal surfaces located inside a rotatable drum, the system comprising:
- the drum, the drum being configured to rotate and to house the one or more parts;
- an electric power source having a first electrode of a first polarity that is configured to charge a plurality of solid particles to produce the beam of electrically active solid particles, the drum including a second electrode of a second polarity opposite the first polarity that is configured to electrically contact the one or more parts;
- projection means configured to direct the beam of electrically active solid particles through an opening of the drum and onto the one or more metal surfaces;
- and
- evacuation means that is configured to remove at least a portion of the plurality of solid particles from the drum and retain the one or more parts inside the drum while the one or more metal surfaces are being polished.
A method for polishing one or more metal surfaces of one or more unattached parts by projecting a beam of electrically active solid particles capable of ionic transport onto the one or more metal surfaces while the one or more unattached parts tumble inside a rotating drum.
A method for polishing one or more metal surfaces of one or more parts by projecting a beam of electrically active solid particles capable of ionic transport onto the one or more metal surfaces, the method comprising:
- electrically charging a plurality of solid particles to produce the beam of electrically active solid particles by connecting the plurality of solid particles with a first electrode of an electric power source, the first electrode having a first polarity;
- placing the one or more parts inside a drum that contains a second electrode that electrically contacts the one or more parts, the second electrode having a second polarity opposite the first polarity;
- at least a step of rotating the drum;
- and
- projecting the beam of electrically active solid particles onto the one or more metal surfaces while the one or more parts tumble inside the rotating drum.
