Hello,

The material used for making machine tool bed is cast iron and mineral cast. These two materials differ in their physical and mechanical properties and are mostly used in the machine structural elements design such as housing, machine tool beds etc.

hope this helps!

Most of the machine tool beds are made of gray cast iron.Cast iron is a high carbon alloy of iron with carbon, usually also with silicon, manganese, phosphorus, sulfur and other ingredients. Contains from 2.11 to 4.3% carbon in the form of cementite or graphite.
