In the case of longitudinal turning tool moves parallel to the axis of the workpiece. For roughing at
longitudinal turning the use of either a straight or arcuated turning tool is favourably. For smoothing
the use of pointed or broad turning tools is favourable.
Transverse turning:
The tooling of the face is known as transverse turning. In the case of transverse turning, the turning
tool is moved at 90 degrees to the turning axis of the piece being turned. In so doing the compound
rest is to be locked. The main cutting edge of the turning tool is to be exactly centred so that no
scar remains in the middle of the workpiece. The arcuated tool is used for transverse turning.

to 1+2: Roughing tools arcuated to the left and or right:
By using them a maximum on mate-
rial is to be cut off in as short a time as possible (without paying attention to the finish on
the surface of the work piece). They can be used for longitudinal and transverse turning.
to 3:
Offset side turning tool:
Used for smoothing (clean surface) in the case of longitudinal
and transverse turning.
to 4:
Outside thread turning tool:
Used for cutting of outside threads.
to 5:
Narrow square-nose cutting tool:
Used for the cutting of grooves and slicing of
workpieces.
When inserting the slicing tool No. 5, pay careful attention to the exactness of the centre
height of the turning tool. Work with low speed and cool the tool (use soluble oil or emulsion
for cooling: serves to lubricate and for the removal of chips.) The slicing tool is to be clamped
as short as possible and at 90° degrees to the workpiece.
to 6:
Right side tool:
Used for the hollowing-out of boreholes. Clamp as short as possible in
order to avoid ascillations of the turning tool which might otherwise occur (uneven
surface).
