Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for treatment of timepiece components by overcoming deformation of the grippers which is very detrimental to good operation.SOLUTION: A method for treatment of timepiece components 10 on a rack comprises the steps of: equipping a rack with a plurality of grippers 2, each being made of the same shape memory alloy, and each being configured to return to a reference shape at a temperature higher than a martensite finish temperature specific to the alloy; bringing the rack to a temperature higher than the martensite finish temperature; bringing the rack equipped with the grippers 2 to a preparation temperature; loading the rack with a batch of the components 10 to be treated; performing the treatment on the rack loaded with the batch of components 10; and unloading the rack. The rack comprises grippers 2 made of a shape memory alloy, the grippers 2 being configured to return to a reference shape at temperature higher than the martensite finish temperature specific to the alloy.SELECTED DRAWING: Figure 4 【課題】良好な操作に非常に有害なグリッパーの変形をなくし、計時器用部品の処理コストを軽減した計時器用部品の処理方法を提供する。【解決手段】ラック上の計時器用部品１０を処理する方法であって、それぞれが前記合金に固有なマルテンサイト終了温度よりも高い温度で基準形状に戻るように構成しているすべて同じ形状記憶合金で作られた複数のグリッパー２をラックに装備するステップと、ラックをマルテンサイト終了温度よりも高い温度にするステップと、グリッパー２を装備したラックを調整温度にするステップと、処理される部品１０の群をラックに搭載するステップと、部品１０の群を搭載するラックに処理を行うステップと、及びラックから外すステップとを有する。形状記憶合金で作られたグリッパー２を有するラックであって、グリッパー２が、合金に固有なマルテンサイト終了温度よりも高い温度で基準形状に戻るように構成している。【選択図】図４
