Apparatus and method for manufacturing lock cylinders

An apparatus for machining lock cylinders comprising:

• a first operating group comprising first stations which comprise a machining station and a repositioning station, each fixed to a first support,
• a second operating group comprising a gripping station configured to grip and release a workpiece,
• wherein said gripping station is configured to support alternately a workpiece in a first machining configuration, for performing a first machining operation thereon, and in a second machining configuration, for performing a second machining operation thereon, wherein said second configuration is different from said first machining configuration so as to expose to said machining station different parts of the workpiece following a repositioning of the workpiece between said first configuration and said second configuration;
• wherein said repositioning station is configured to reposition said workpiece between said first machining configuration and said second machining configuration,
• and wherein said repositioning station comprises:
• a first repositioning body and
• a second repositioning body,
• wherein said first repositioning body is configured to perform, in sequence, the following:
• remove said workpiece from said gripping station, which releases said workpiece,
• move said workpiece so as to make said workpiece available for gripping by said second repositioning body;
• wherein said second repositioning body is configured to perform, in sequence, the following:
• grip said workpiece supported by said first repositioning body, which releases said workpiece;
• transfer said workpiece into a position in which the workpiece is available for gripping by said gripping station;
• and
• wherein said first repositioning body is configured to rotate a workpiece gripped by said first repositioning body through a working angle.
