Production method of thin plate and thin plate support for chucking employed in the method

摘要

A production method of a thin plate includes preparing a thin plate support with a receptacle cavity having a bottom surface formed with a complementary three-dimensional pattern with a three-dimensional pattern of one side surface of a machining object, setting the machining object within the receptacle cavity with mating the complementary three-dimensional pattern with the three-dimensional pattern on the one surface of the machining object, chucking the thin plate support carrying the machining object set in the receptacle cavity on a machine tool, driving the thin plate support together with the machining object to rotate, and machining the machining object as being driven to rotate on the machine tool from the other side of the machining object by means of a cutting tool.
