Cross-adjustment of the tailstock = 300mm x Tan 1°. The tailstock must be cross-adjusted by
approximately 5.236mm.
Img. 4-13: Tailstock
ATTENTION!
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.
4.18.2 Turning short tapers with the top slide
Short tapers are turned manually with the top slide. Swivel the top slide to the required angle.
The infeed is achieved with the cross slide.

Loosen the four clamping screw at the top slide.

Swivel the top slide.

Clamp the top slide again.
4.18.3 Turning of cones with high precision
There are different possibilities to machine a cone on a common small lathe:
1. By twisting the top slide by setting the setting-angle with the angular scale. But there the
graduation of the scale is too inaccurate. For chamfers and conic passings the graduation of
the angular scale is sufficient.
