TZ 200.02 Engineering drawing: casting
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.
