Abstract
This invention provides a polishing apparatus using a polishing material freely varying its shape in a tri-dimensional space in accordance with the shape of a work, and capable of polishing a narrow, recessed surface inaccessible to human hands or a tool, and a polishing method used therefor.
Claims15
A polishing material prepared such that a fluid containing grinding particles is solidified in accordance with the shape of a work, with a controlled orientation of said grinding particles in the presence of a magnetic field, solidified material is moved relative to the work, thereby polishing or grinding the work.
A polishing material prepared such that a fluid containing grinding particles is solidified in accordance with a surface of a work with a controlled orientation of said grinding particles in the presence of an electric field, wherein the polishing material is moved relative to said work, thereby polishing or grinding said work;
- wherein the main ingredient of solvent contains at least one of the compounds represented by the following general formula,
- R1—COO—R2
- where R1=CaH2a+1,(10≦a≦25),and
- where R2=CaH2a+1,(1≦b≦25);
- wherein the grinding particles contain at least one of aluminum oxide and diamond whose particle diameter distribution has the central point at 2 to 9 μm.
A polishing material prepared such that a fluid containing grinding particles is solidified or gelatinized in accordance with the shape of a work, and the fluid turned solid or gel is moved relative to the work, thereby polishing or grinding the work;
- wherein the fluid containing grinding particles is an electric rheology fluid capable of controlling the orientation of grinding particles in the presence of an electric field, and is solidified or gelatinized in the presence of an electric field.
A grinding particle body for abrasion-grinding wherein:
- the main ingredient of solvent contains at least one of the compounds represented by the following general formula,
- R1—COO—R2
- where R1=CaH2a+1,(10≦a≦25), and
- where R2=CaH2a+1,(1≦b≦25);
- wherein the grinding particles contain at least one out of aluminum oxide or diamond whose particle diameter distribution has the central point at 2 to 9 μm.
A grinding particle body for abrasion-grinding wherein:
- the main ingredient of solvent contains at least one of the compounds represented by the following general formula,
- R1—COO—R2
- where R1=CaH2a+1,(10≦a≦25), and
- where R2=CaH2a+1,(1≦b≦25);
- wherein the grind particle body contains as its main ingredient ferrite particles whose particle distribution has the central point at 2 μm or less.
