There are provided a work material and a gripping mechanism capable of shortening a handling time not involved in works, shortening a time required for producing a plurality of finished members as a whole, accurately positioning the work material even if there is an axial dimension error, lessening waste of a material and lightening a burden for disposing discharged chips. The work material (100) has a shape in which a plurality of raw blanks (101) that become products by material removing works is integrally molded. The gripping mechanism (110) comprises a free moving means (120) that relatively and freely moves a gripper (112) and the work material (100) and a positioning means for defining axial gripping position of the gripper (112) and the work material (100). |
