Title:
POLISHING TOOL HOLDER, POLISHING TOOL, AND POLISHING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/023876
Kind Code:
A1
Abstract:
A polishing tool (1) stores and holds, in a storage unit (52) of a polishing tool holder (4), a reference dimension (M) which is the initial dimension of a linear abrasive material (2), the number of polishing operations, and a wear pattern (P) in which the amount of wear generated by one polishing operation is associated with the number of polishing operations. When a rotation detector (53) detects a rotation state, a control unit (51) of the polishing tool holder (4) adds 1 to the number of polishing operations to update the number of polishing operations, and acquires the amount of wear by referring to the wear pattern (P) on the basis of the updated number of polishing operations. In addition, when the control unit (51) detects the end of the rotation state, the control unit (51) performs an abrasive material ejection operation in which a motor is driven to operate a movement mechanism (22) so that a polishing brush (3) is moved in the axial direction by a distance corresponding to the amount of wear.
