Machine-based Material Processing - Part: Turning
Documents for the Trainer

Chinese
Item No.: 45076

The training course "Mechanical Materials Processing - Turning Part" deals with the machining production processes of turning in accordance with the training framework plans for metal professions (Lfd. No. 12 c "Turning"). The various turning skills such as centering, drilling, thread production, taper turning, knurling and deburring are dealt with in detail. A second focus is on the lathes and their functions, as well as on professional operation and the testing and adjustment of machine functions. In addition, the tools, the alignment and clamping of tools and workpieces are described.
Various project tasks are dealt with in 12 practical exercises, each with work information, parts lists and work planning forms as well as control and evaluation sheets. The exercises are structured according to the lead text method and follow the model of the complete action. Thus they are particularly conducive to action and social competence. The exercises can be worked on both individually and in groups.
The complete training course in a collective folder, consisting of the trainer's set with trainer's guide, slides on CD, text volume, learning success controls and suggested solutions as well as the documents for the trainee.
