Fixture for multiple parts & tandem milling example for superb finishes.

Hi Frank

The fixture holds the parts using o rings that compress to suit the individual parts. They are compressed by a cam plate moving bronze followers. Each station has a sleeve which can be changed for different component sizes. The cam plate is moved by jacking screws and locked with a pneumatic toggle clamp. Unloading uses a valve lapping rod with a rubber suction cup on the end. Here is a view of the inside, the cam plate can be seen on the left.

Hadn't thought of the fixture being made to accommodate more sizes. That is a well thought out fixture you have there. good for possibly millions of parts
I usually say fewer than 4 like parts do a set up work up fixturing above 4 units. when batches can be in the 100s and repeat batches are likely spend the extra time to make a better fixture. when the possibility of 1000s per batch, get crazy and make your holding device as near to fully automatic as possible.
