5. Achieving optimum results and avoiding incorrect usage
■
Use of suitable processing tools.
■
Adaptation of revolution setting and feed to the material, work piece and tool.
■
Tension tools as far into the tool holder as possible (short projecting length).
■
Tension turning element as far into the chuck as possible (short projecting length).
■
Support length pieces with a tailstock or bezel.
■
The use of coolant and lubrication to increase the durability of the tool, improve surface quality and
accuracy.
■
Clamp processing tools and turning elements on a clean clamping surface.
■
Lubricate machine sufficiently.
■
Set the bearing clearance and guides correctly.
Longitudinal turning
■
For longitudinal turning, the turning steel moves parallel to the axis of the work piece.
■
To rough, it is advantageous to use straight or curved turning steels.
■
To finish, use sharp or wide turning steels.
Face turning
■
The processing of end planes is referred to as face turning.
■
When face turning, the turning steel is moved at right angles to the rotating axis of the turning
element. The tool skid should be locked when doing so.
■
The main cutting edge of the turning steel is to be set precisely to the centre so that the turning
element centre has no nose.
■
The curved turning steel is used for face turning.
