Figure 7-57.—Aligning vise jaws using an indicator.
2. Mount and position a vise on the milling
machine table so the thrust of the cutter is
toward the solid vise jaw.
3. Align the solid vise jaw square with the
column of the machine, using a dial indicator
for accuracy.
4. Mount the work in the vise, allowing the end
of the work to extend slightly beyond the vise
jaws.
5. Raise the knee until the center of the work is
approximately even with the center of the
cutter.

6. Lock the knee in position.
7. Set the machine for the proper roughing
speed, feed, and table travel.
8. Start the spindle and pick up the end surface
of the work by hand feeding the work toward
the cutter.
9. Place a strip of paper between the cutter and
the work, as shown in figure 7-59, to help
pick up the surface. When the cutter picks up
the paper there is approximately 0.003-inch
clearance between the cutter and the material
being cut.
10. Once the surface is picked up, set the saddle
feed graduated dial at ZERO.
