Cast Iron Lathe Bed, Sand Casting for Machine Parts, Iron Castings for CNC Machine, Grey Iron Castings, Ductile Iron Lathe Parts in China Foundry
Why is a lathe bed made of cast iron?
Cast iron is used as the "material of choice" for many machinery housings or bases because it is extremely stable in its structure. Certainly it is subject to thermal expansion and contraction, but the crystal structure of cast iron makes it "hold its shape" in applications ranging from machines and machine parts to cookware. And in things like a lathe bed, we need the thing to be "the same" every day and all the time so we get accurate, consistent work. Cast iron also suppresses high frequencies generated during machining.
