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.
