Abstract:
A polishing device includes a motor movement mechanism and a second motor that rotates a workpiece. The motor movement mechanism moves the workpiece in a direction tangential to a radially outer circumferential surface of a polishing member and moves the workpiece in a direction orthogonal to a rotational axis of the polishing member.
Abstract:
Provided is a polishing composition that is produced at low cost and can impart high-grade mirror finishing to ceramic. The polishing composition includes abrasives made of carbide, and is used for polishing ceramic.

Provided is a polishing composition that is produced at low cost and can impart high-grade mirror finishing to ceramic. The polishing composition includes abrasives, has a pH of 6.0 or more to 9.0 or less, and is used for polishing ceramic.
Abstract:
A polishing device includes a polishing member, a tool, and a contact mechanism. The polishing member includes a polishing surface that is shaped in conformance with the shape of an end of a workpiece. The tool functions as a shape-processing cutting tool or a surface modifying tool that has the same shape as the shape of the end. The shape-processing cutting tool processes the polishing surface of the polishing member to be shaped in conformance with the shape of the end. The surface modifying tool modifies the polishing surface to be shaped in conformance with the shape of the portion to be polished. The contact mechanism brings the tool into contact with the polishing surface of the polishing member.
Abstract:
The present invention relates to a polishing method using a polishing tool provided with a polishing pad including a polishing surface shaped in conformance with a curved surface of an object to be polished to efficiently and uniformly polish the curved surface of the object. A polishing tool of the present invention is provided with a polishing pad including a polishing surface shaped in conformance with a curved surface of an object to be polished to uniformly contact the curved surface of the object. The polishing pad preferably has a Shore A hardness of 5 or greater. A polishing method of the present invention uses a polishing tool including a polishing surface shaped in conformance with a curved surface of an object to be polished to uniformly contact the curved surface of the object and polish the curved surface of the object.
