Abstract- Centrifugal Casting, sometimes called roto-casting is a metal casting process that uses centrifugal force to form cylindrical parts. This paper concerns to the proposed design of centrifugal casting machine. To produce turbine bearing.
The dimension of the bearing to be produced as follows: Length=700mm, Diameter=1200mm. A bearing used in steam turbine should have good mechanical properties like strength, stress, wear, rigidity etc. A centrifugal casting is the only process by which such type of heavy axisymmetric job can be produced.
Due to Centrifugal force (the main aspect of centrifugal casting process), the product homogeneity can be achieved in terms of mechanical properties than other casting processes. For this, a special purpose horizontal axis centrifugal casting machine will be developed. In this paper, the proposed design and function of the components have been covered.

INTRODUCTION Today, casting is the sixth largest manufacturing industry in the whole world. Cast metal parts account more than 50% of the total weight of tractor and for more than 90% of an automobile engine.
High precision castings are used in turbine vanes and blade in an aircraft jet engine. The reason for the widespread use of casting lies wholly in its economy and time factor. In terms of time, it is the quickest method producing components, as it fairly easily done. Economically, it is desirable as machine appears to be the most expensive method of producing an engineering component. Hence, without casting automobile, household appliances and machine tools would have become costlier.http://www.centrifugalcastmachine.com/Iron-Pipe-Centrifugal-Casting-Machine/90.html
