PROBLEM TO BE SOLVED: To provide a raw material constitution which is especially made of dental materials and is also reliably adaptable to the mass production of raw materials (12) which are cut for manufacturing dental prosthetic materials.SOLUTION: The raw material (12) is combined with a holder (16) which is combined with its raw material in a fixed state and an adapter (22) which detachably combines the holder (16) and the raw material (12). The adapter (22) has an operating surface through which a raw material unit can be detachably attached to the inside of a workpiece insertion part or to the top of the workpiece insertion part of a cutting device.COPYRIGHT: (C)2009,JPO&INPIT【課題】特に歯科材料からなり歯科補綴材を製造するための切削加工される未加工材(12)の大量生産にも確実に適応する未加工材構成を提供する。【解決手段】未加工材(12)はその未加工材と固定的に結合されたホルダ(16)と、前記ホルダ(16)と前記未加工材(12)を取り外し可能に結合するアダプタ(22)に結合され、前記アダプタ(22)が作用面を有していて、それを介して前記未加工材ユニットが切削装置のワークピース差込み部内またはワークピース差込み部上に取り外し可能に取り付け可能とする。【選択図】図1
