Claims28
A polishing device which polishes a material to be polished by spraying a polishing liquid onto the material, said polishing device comprising:
- a positioning jig including position detection means for checking an incidence position of a polishing liquid jet;
- means for attaching the positioning jig to the polishing device such that the positioning jig is exchangeable for the material to be polished;
- means for spraying the polishing liquid jet onto the position detection means of the positioning jig, to thereby determine a relative spray position and a relative spray angle of a polishing liquid spraying nozzle of the polishing device with respect to a position of the material to be polished.
A method of polishing a material by spraying a polishing liquid thereto from a polishing liquid spray nozzle of a spray polishing device, said method comprising:
- spraying the polishing liquid onto a positioning jig at position detection means thereof for checking an incidence position of the polishing liquid on the positioning jig, to thereby determine a relative spray position and a relative spray angle of the polishing liquid spraying nozzle of the spray polishing device with respect to a position of the material to be polished;
- exchanging the material to be polished for the positioning jig;
- and
- polishing the material to be polished.
A positioning jig for a spray polishing device which sprays a polishing liquid to a material to be polished, wherein the positioning jig comprises:
- a position detection member for use in determining a relative position of a polishing liquid spraying nozzle of the spray polishing device with respect to the material to be polished;
- wherein the position detection member is provided at a position such that a line connecting:
- (i) a center of a nozzle hole of the polishing liquid spray nozzle and (ii) a position where an arbitrary point of the material to be polished during polishing, intersects a surface of the positioning jig.
A positioning jig for a spray polishing device which sprays a polishing liquid to a material to be polished, wherein the positioning jig comprises:
- a position detection member for use in determining a relative position of a polishing liquid spraying nozzle of the spray polishing device with respect to the material to be polished;
- wherein the position detection member comprises a projection.
A positioning jig for a spray polishing device which sprays a polishing liquid to a material to be polished, wherein the positioning jig comprises:
- a spherical surface that is substantially the same as a surface shape of the material to be polished;
- and
- wherein a center of the spherical surface of the positioning jig corresponds to a position at which a center of the material to be polished is to be located for polishing.
A positioning jig for a spray polishing device which sprays a polishing liquid to a material to be polished, wherein the positioning jig comprises:
- a position detection member for use in determining a relative position of a polishing liquid spraying nozzle of the spray polishing device with respect to the material to be polished;
- wherein the position detection member comprises a pressure sensor.
