Pillar type bed,
designed for operating convenience, is of smooth and
rigid construction. It is equipped with ground and
chrome plated pillars for guiding and supporting the
carriage. These ways are of heavy cross-section with
large bearing surfaces to assure accurate carriage
alignment and to minimize wear. Guards, attached to the
carriages, prevent damage to the ground surfaces of the
machine are available in various size bed lengths to
provide travel lengths as per convenience.
The bed contains ample chip space
and is provided with chip removal from either side of
the machine. A wide drip ledge returns any coolant
overflow and a large screened opening over the coolant
reservoir permits rapid coolant returns.
The headstock is
of box construction and of heavy cross section. It is
positioned on the machine bed to provide maximum
rigidity and permanent alignment with the carriage ways.
To assure accuracy, quiet operation and maximum wearing
qualities, the headstock gears are of hardened and precisioned shaved alloy steel. In addition all shafts
are heat treated alloy steel. The spindle drive is
accomplished through spiral bevel gears. The machine is
equipped with D.C drive for variable speeds as per job
spindle, lead screw machines (optional) employ a
mechanical reversing mechanism which enables the spindle
to operate in both directions. Thus, both right-hand and
left-hand threads can be produced simultaneously.
The headstock is totally enclosed
to exclude all foreign matter and to enable use of a
flood type lubrication system. An oil sight glass is
provided to facilitate maintenance of the proper oil
The DC drive
facilitates variable speeds which enable efficient
spindle speeds for the desired threading diameter.
Higher or lower speed ranges are available when required
for special uses.
