Cross-adjustment of the tailstock
INFORMATION
The tailstock may be cross-adjusted by approxi - 10mm to the front or the back.
Example:
A 300mm long shaft is to be taper-turned between the centres with an angle of 1°.
Cross-adjustment of the tailstock = 300mm x Tan 1°. The tailstock must be cross-adjusted by
approximately 5.236mm.
CAUTION!
Check clamping of the tailstock and the
sleeve, respectively for the turning jobs
between the centres!
Tighten the securing screw at the end
of the lathe bed in order to prevent the
tailstock from unintentional drawing-
out of the lathe bed.
