5.2 Control and indicating elements

5.2.1 BD-11G Lathe

Clamp the turning tool into the toolholder.

The tool must be clamped firmly and with the least possible overhang in order to absorb well and reliably the cutting

force generated during the chip formation.

Adjust the height of the tool. Use the tailstock with lathe cen - tre to adjust the tool to the required height. If

necessary, use steel spacer shims under the tool to get the required height.

For the facing process, the cutting edge of the tool must be exactly aligned with the height of the lathe centre to

obtain a shoulder-free face. The facing process is a turning operation in which the turning tool feeds

perpendicular to the axis of rotation of the workpiece in order to produce a flat surface. The different methods are

transversal facing, transversal slicing and longitudinal facing.
