4. PUTTING THE LATHE INTO OPERATION
4.1 Spindle reduction tubes
The efficiency of the bar guiding while in rotation in the lathe is determined by the clearance
between the spindle reduction tube and the rotating bar. The greater the clearance is, the
more frequent the vibrations are.
Using reduction tubes helps to decrease this clearance. Guiding is thus improved, but, in
addition, the insertion of the bar into the clamping device of the lathe is made much easier.
The inside diameter of the reduction tubes should be chosen in terms of the diameter of the
bar (diameter of the bar + 1 mm), but should always be larger than that of the diameter of
the feeding pusher.
For inserting and removing the spindle reductions, move the bar feed system using the
retraction device (Chapter 7/ Point 8).
Spindle reduction tubes are available from LNS America, upon request.
