Simple indexing consists of a series of preset holes in a backing plate, these divisions are provided for the most common angles (such as 90 °, 45 °, 30 °, etc). The remaining divisions of a circle are provided by manually rotating the dividing arm using index plates. Tables or calculations are required to use this method. Indexing plates

The backing plate on a lathe is used to mount the chuck to it and is the adapter to the lathe spindle.
Using a drive plate on a lathe requires removing the chuck and the drive plate is attached in its place onto the spindle.
Face Plate is used on Lathe machine. It is just like lathe chuck. irregular shape job clamp on face plate by clamps, bolts.
Direct Indexing, Simple Indexing, and Angular Indexing
what is pre-indexing
On a wood turning lathe, the faceplate is screwed to the piece of wood, then the faceplate is held in place by the chuck. This facilitates free-wheeling the opposite end for such items as bowls. Almost similar to a wood turning lathe, the face plate on a metal lathe is a device that is used instead of a chuck. It allows a workpiece to be clamped or bolted to it for machining.
what are the differents between preindexing and post indexing?
The spindle of a lathe is a rotating hollow tube within, and protruding the head stock and to which a chuck, drive plate or facing plate attaches and rotates to enable machining. It is housed within the head stock in bearings and has some gears around it which is driven by other gears which in turn is driven by an electrical motor.
