Claims

[Scope of utility model registration request]

In a loader for a multi-spindle lathe, the main shaft of the multi-spindle lathe includes a running body that runs above the multi-spindle lathe in parallel with the front surface of the lathe, and a loader chuck provided at the lower end of a hanging shaft that hangs down from the running body. The loader chuck is constituted by a rotary chuck base that rotates facing the chuck, and four or more chucks arranged circumferentially on the surface of the rotary chuck base facing the main shaft chuck and each gripping a workpiece. A multi-spindle lathe loader in which the spacing between chucks matches the spacing between spindle chucks.
