per form heavier cuts, such as drilling with a
2-inch-diameter TungSix-Drill indexable-insert
drill from Tungaloy. Before, when machining
6-inch stainless steel hubs, the shop had to first
drill the blanks with this indexable-insert drill on
a VMC or another lathe, and then send them to
the old lathe. Now, everything can be done on
one machine, which simplifies job scheduling,
Mr. Harvey says.
The shop also is reaping benefits from the Parat

recommended for the machine, which features
four detents, ever y 90 degrees, for easy tool
positioning. It also features 40 angular location
points, at every 9 degrees, for "off-90 degree"
tool positioning. (A serrated plate that is screwed
down to the cross-slide and the toolpost's mating
serration enables the 9-degree indexing.) Toolpost
position repeatability is said to be 0.0002 inch.
Mr. Harvey says JBC also has other ideas for
how to take further advantage of the E50's capa-
bilities, including making use of the machine's
rigidity and 2,248 pounds of Z-axis feed force to
try broaching a blind key for an upcoming job.
JBC's E50 is configured with a Parat tooling system,
which has detents for 90-degree indexing and a
serrated, mating plate design to enable positioning
every 9 degrees to a repeatability of 0.0002 inch, in
most cases eliminating the need to measure between
tool indexes.
