Cross-Adjustment Of The Tailstock; General Operating Instructions; Longitudinal Turning - Optimum OPTiturn TH4610D Betriebsanleitung

4.19.1 Cross-adjustment of the tailstock

The cross-adjustment of the tailstock is
used for turning long, thin bodies.

Loosen the adjusting screws in the
front and in the rear of the tailstock.
By alternately loosening and tightening

the two (front and rear) adjusting
screws, the tailstock is moved out of the
central position. The desired cross-ad-
justment can be read off the scale.

Re-tighten the adjusting screws of the
tailstock.
INFORMATION
The tailstock may be cross-adjusted by approximately + - 13 mm 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.

General operating instructions

4.20.1 Longitudinal turning

In the straight turning operation, the tool
feeds parallel to the axis of rotation of the
workpiece. The feed can be either manual
- by turning the handwheel on the lathe
saddle or the top slide - or by activating
the automatic feed. The cross feed for the
depth of cut is achieved using the cross
slide.
