LOWER HEAD ALIGNMENT:
The top of the lower flush cup should be about .005" below the table .To check it, take a
surface gage and an indicator and zero out the dial on the table. Swing the indicator over
to the inside ring of the flush cup and determine how far below the table the flush cup is.
The flush cup must be held up while doing this. The thickness of a new flush cup on the
inside ring is .640" and the outside ring is .628". If the reading shows the distance to be
more than .005", check the thickness of the cup. If the cups are scraped or chipped or
undersize, the cup should be replaced. Sodick provides a round gage that sits on top of
the flange that holds the lower flush cup on. The top of the gage represents where the top
of the flush cup would be.

The AWT unit can be adjusted by several parameters. These parameters are located in the
SET, MACHINE screen. There are also a few adjustments available in the electrical
cabinet located behind the machine tool on the A320D and A530D types, and on the left
side of the machine tool on A350, A500, A600, A750 and A1000 types. The wire should
be square before performing the following procedure. Also, the AWT pipes have an I.D.
of .7mm or 1mm and the O.D. is .079 inches. The size of the top pre-guide on the
threader is .4 and the lower pre-guide should match the wire diameter.
