Claims

[Scope of utility model registration request]

A collect chuck that is formed concentrically with a workpiece having a workpiece position eccentric from the center by a predetermined dimension and capable of holding the workpiece;
An eccentric plate is formed to be rotatable about a shaft provided around the 1/2 position, and an index is provided on the peripheral edge of the eccentric plate and operates to protrude and retract from the side opposite to the holding side of the collect chuck. An indexing device having a pin, a bearing portion for supporting a shaft portion of the eccentric plate is formed, and an indexing hole into which the indexing pin can be inserted is formed at a symmetrical position with respect to the bearing portion, A mounting device for machining an eccentric position, comprising an indexing plate having a gripped portion centered at the center of the collector chuck.
