Engineering drawing: casting (TZ 200.02)

Engineering drawing: casting (TZ 200.02)

from raw casting to finished machine part, GUNT course: engineering drawing

Code TZ200.02


  • A bearing housing made from sand-cast aluminium is used in teaching as an example to illustrate the subject of cast parts in a detailed and practical way.
  • TZ 200.02 comprises a raw casting of a bearing housing, manufactured and polished in a foundry, and a finished part of the same bearing housing, which has been machined after being cast.
  • The machined part has also been prepared as a cutaway model.
  • The two components can be used to describe the process from forming to machining.
  • An ideal learning situation would be to allow two or three students to study the model set together.
