Considerations
- Automatic, independent vs manual and all jaws moving together - for any number of jaws
- Collet vs no collet.
- Automating by turning a screw vs a piston that locks chuck
- Indexing of workpiece (hold workpiece at specific angles), vs. indexing of the rotation motion (with CNC), vs. indexing rotation with an indexing (dividing) head [1]
Operation
- How to align a workpiece in 4-jaw independent (off-center) chuck using a dial indicator and a sharpened point - [2]
- Aligning tail piece to chuck - first use a very straight rod (such as cylinder rod) and then set adjustment screws on tailstock to move side to side. What about up and down? [3]
- Indexing chuck - allows you to hold workpieces in a certain orientation, such as a pipe cross - at 90 degrees for 90 degree machining - [4]. This appears solved with CNC lathe/mill combination with multiple heads. Indexing chucks can also be automated so they turn the piece automatically - [5].
- Large chuck - [6]
Automatic Lathe Chuck
- Means that it holds and releases automatically. Simple mechanism is turning the hold with a motor - [7]
- More complex is using a piston to close the chuck.
