the graduated dials are marked in increments of
0.001", with one full revolution moving the table
0.125".
Locks
the table of this vertical mill has locks to secure
the table in position along each axis of move-
ment. locking the table reduces unwanted move-
ment and reduces error in milling operations.
use the table, saddle, and knee locks shown in
figures 19–20 to secure the table in position.

Limit Stops
limit stops increase repeatability in milling
operations. positioning the stops along the table
slots limits the distance the table or saddle can
travel (see
figures 21–22).
