FEATURES:
The bed is of
large width, the side wall of the bed is constructed of
double-rib plates, and internal rib plate consists of
box-type bevel ribs. The rigidity of this type of lathe
increases by up to 1/3 times as compared to other styles.
Load strength
is impressive. A workpiece weighing 6,000 lbs (this rating
for 120" Center) can be worked with the chuck only, no
steady rest support. Using one steady rest this can be
increased to 7,000 lbs and using two steady rests or a
steady rest and tailstock support an 8,000 lb workpiece can
be turned. Permissible cutting force (PZ) is 21372N, and (PX)
is 7845N. Size/accuracy of machining is up to Grade II.
These lathes
are suitable for general turning such as internal and
external, taper turning, facing, cutting Metric, Inch,
Module, and Diametral threads, and are also used for drawing
oil grooves and keyways.
The forward
and reverse rotation and braking of the spindle are
hydraulically controlled as well as the lubrication of the
headstock and feed box.
Operations
are concentrated. On the Apron is the Rapid 4-Way Control
and this single lever also activates taper cutting through
power to the tool compound (32" only, 25" has a standard
factory installed taper attachment) for short tapers, and
when in concert with longitudinal motion for long tapers.
The
construction and rigidity of transmission are higher than
those of universal lathes. Precision is repeatable and yet
heavy duty cutting can also be obtained. Guideway which is
made of “FQ-1” wear-resisting, inlaid materials allow for
smooth and nimble
carriage
motion and extends the service life. A lubrication system
circulates from the external independent storage tank which
maintains better flow, cleaner lubricity, and ultimately
increases precision as well as longevity.
Spindle bore
will handle 4" bar stock and the machine is neat,
functional, rugged, easily maintained, well conceived, and
easy to keep clean. |
