Title:
加工物を成形する方法
Document Type and Number:
Japanese Patent JP6587688
Kind Code:
B2
Abstract:
There is described a method, apparatus and shaping tool for shaping a workpiece. The tool comprises a flexible support surface on which are mounted a number of rigid pellets (84) carrying abrasive material. The tool is driven, in contact with the workpiece surface (S), to perform a ductile grinding operation which results in a finished surface of reduced roughness as compared to conventional grinding operations, while achieving significantly higher material removal rates than comparable ultra-precision grinding techniques. A procedure for preparing the tool for operation by conditioning the tool against a conditioning surface is also described. An exemplary application for the method and apparatus is in the preparation of moulds for moulding curved glass components for use in display screens, in which process a silicon carbide mould cavity surface is shaped using the method to produce a mould cavity surface with a smooth surface finish.
