Quality parts start at the ends

Quality parts start at the ends

End working machines
End working machines can eliminate subsequent machining operations by cutting both part ends simultaneously.

For large-scale between
centers turning
applications, end working
generates accurate reference
points for producing
quality parts.

And according to Seneca Falls Machines,
a maker of technologies for enhancing turning
applications, being able to
simultaneously work both
part ends saves time and
improves concentricity,
roundness and squareness
of machined surfaces.
In addition, these more
accurate centers lead
to more uniform stock removal and less cutting
pressure variation,
especially when turning
stock off a part’s O.D. later
in the machining process.

End working machines
from Seneca Falls Machines,
for example, are CNC
double-end tool-rotating
machines that perform work on both ends of a
stationary part gripped in
an automatic fixture. The
rotating tools face each
other on the same centerline
for good concentricity,
roundness and squareness
between machined surfaces
on both part ends.

End working is usually
the first or second
operation in the machining
process and is intended
to prepare parts for
subsequent operations, or
it can be the only turning,
facing, centering and
threading done on a part.
As such, these machines
can eliminate subsequent
machining operations,
increase productivity or
help decrease the part
process scrap rate.

While end working
typically is used for
centering and facing a part
to be loaded on a lathe
between centers for turning,
today’s end working
machine technology
allows shops to do many
other operations, such as
machining I.D.s, faces and
O.D.s of a tube at both ends
concentrically at the same
time or face, turn, drill and
thread both ends of a shaft
simultaneously.
