Features
- The
bed is manufactured from high grade cast iron
( FC-25 ) for maximum rigidity and no deformation
after years of operation.
- The
grears in the headstock and the spindle are
precision manufactured from Chrome-molybedinum
alloy steel, carburized and precision ground.
The spindle is supported at 3 points, and
runs on high precision taper roller bearings
for maximum stability.
-
The enclosed type gear box employs oil bath
lubrication. It provides convenient speed
change and cuts imperial, metric, diametral
pitch and module threads.
-
The massive tailstock
allows for heavy duty machining. The tailstock
is locked securely, and does not slip while
the tailstock quill is moving.
