TZ 200.02 Bearing Housing, Casting
Education / GUNT Hamburg / Mechatronics / Engineering Drawing /

A bearing housing made from sand-cast aluminium is used in teaching as an example to illustrate the subject of cast parts in technical drawing in a detailed and practical way. TZ 200.02 comprises two elements: an unmachined cast part, professionally 'polished', as it is delivered from the foundry; and a post-machined cast part additionally presented in the form of a cutaway model. This enables the entire process, from the shaping to the cutting, to be covered in the lesson. Optimal learning is established when one model is used with two/three students.

Learning Objectives / Experiments

Technical drawing:
- Drawings of cast parts and their special features: machining 
  allowances, mould drafts, shrinkage, sectional views
- From the cast part to the finished part: production-oriented and 
  standard dimensioning for subsequent machining
- Manufacture of cast parts by the sand-casting method; manufacturing 
- Machine and tool selection, length measurement exercises - machine 
  elements and their function
