MODEL CWP-20
Precision Lathe
One Model to handle a
wide range of part sizes
Precision Manufactured
High Accuracy Rotation
Wide Range of Accessories
For all Arc Welding Processes
Introduction
The Jetline CWP-20 precision lathe is designed and
built to provide superior accuracy and performance for even the most demanding GTAW (gas
tungsten arc welding) or PAW (plasma arc welding)
applications.
The headstock, tailstock, frame, and carriage
components are made of cast iron for stability
and accuracy. The spindle has a 0.8” (20 mm)
through-hole which can be used for gas purging
or specialized tooling. The front of the spindle has a
ange designed to accept the supplied three jaw
chuck, four jaw chuck, and faceplate.
Weight carrying capacity is 100 lbs (45 kg). The lathe
accepts parts up to 20” (500 mm) in length with
a maximum diameter of 5”(127 mm). Headstock
spindle rotation has an accuracy of .001” (0.025
mm) TIR.
Description
Frame — The lathe’s cast iron frame has machined
ways that mount the headstock and on which the
tailstock and torch mounting carriage move.
Headstock — The headstock spindle has a
through-hole and rotates in the headstock housing on pre-loaded, tapered roller bearings. The
bearings are designed to provide smooth, precise
rotation and, because they are pre-loaded, also
have the ability to carry the welding current.
The headstock spindle is driven through a tensioned
timing belt by a high-quality DC servo motor tted
with a tach-generator. The supplied 9640 microprocessor control uses menu-driven software to permit
the setting of rotational speed and the delays for
the starting and stopping of travel. The control indicates speed before and during welding.
— The tailstock slides on the precision
ground ways on the frame of the lathe. A lever is
provided to lock the tailstock when it is in its desired
position. The tailstock uses a pneumatic spindle
which extends to clamp the part into position
when welding. Clamping pressure is adjustable;
activation of the spindle movement is by a manual
air valve.
Tailstock
The tailstock spindle has a Morse taper bore to accommodate a range of accessories. This can be
used to hold an optional live center, faceplate, or
custom designed tooling.
— The torch mounting carriage
slides on the machined ways of the frame. Positioning of the carriage along the length of the frame is
through a manual wheel that engages a rack and
pinon drive. Mounted on the top of the carriage
is a micrometer adjustment slide used for manual
fore/aft torch positioning.
Torch Mounting
The slide carries a vertical column that provides
coarse vertical torch adjustment. A bracket
mounted on the column carries a vee-style torch
holder which is mounted on two precision slides
for cross-seam and torch height adjustment. The
bracket also includes manual tilt adjustment.
