Feeding motors
The machine has two feeding motors, one
for carriage feed (A) and one for the move-
ment of the pivoting arm (B).
The feeding motor's speed is changed in
the gear housing and the screw worm pro -
duces a slow motion, which in turn drives
the worm wheel of the saw head.
Note that the gear housings and the
motors' gear wheels are different for the
carriage and arm feed, and therefore must
not be confused.
At the screw's other end, there is a bearing
housing with axial and radial bearings.
A = carriage feed
B = arm feed
