Provided is a workpiece material and a grasping mechanism which are capable of performing accurate positioning, even if a dimension error in an axial direction is caused, while reducing a handling time that is not involved in a working and reducing the overall time required to obtain a plurality of work completion members, and which reduce a load of the disposal of discharged swarf with less waste of a material. A workpiece material (100) has a shape obtained by integrally molding a plurality of formed materials (101) that is to be a product by a material removal work. A grasping mechanism (110) is provided with a free movement means (120) for causing a grasping unit (112) and the workpiece material (100) to be relatively freely moved and is provided with a positioning means for defining an axial-direction grasping position of the grasping unit (112) and the workpiece material (100).

B29C 45/14 - Moulage par injection, c.-à-d. en forçant un volume déterminé de matière à mouler par une buse d'injection dans un moule ferméAppareils à cet effet en incorporant des parties ou des couches préformées, p. ex. moulage par injection autour d'inserts ou sur des objets à recouvrir
A work supply apparatus has: a work containing section (110) which contains a plurality of works having various lengths; a pressing member (130) which presses out a work (W) contained in the work containing section from the work containing section (110) by pressing the work; and a work replenishing section (122) which replenishes the work containing section with the work. The work supply apparatus replenishes the work containing section with the work, and supplies the work in the work containing section to an operating position by means of the pressing member (130). The work replenishing section has a work positioning member (125) which positions the work at a position from which the work can be replenished to the work containing section. The work positioning member (125) is disposed such that the position thereof can be adjusted corresponding to the work, and the shift quantity of the pressing member (130) is adjusted based on the distance between the reference position (122a) and the work positioning member (125).

Provided is a coolant supply structure for a turret tool head wherein a central portion of an intermediate shaft can be effectively utilized as a hollow portion, and it is not necessary to make a shaft, such as a drive shaft, which is to be inserted in the intermediate shaft, hollow. A coolant supply structure is provided in a turret tool head (1) which is provided with a turret (12) having a tool (T) mounted thereon, a hollow rotating shaft (15) for rotating the turret (12), and a hollow intermediate shaft (19) arranged in the rotating shaft (15) to supply a coolant to a tool mounting portion of the turret (12). A tubular member (23) is inserted in the intermediate shaft (19), and a space defined between the tubular member (23) and the intermediate shaft (19) forms a passage (24) for the coolant.
