Grey Cast Iron – Machinability


Gray cast iron is known for its excellent machinability due to its unique microstructure and composition. The graphite flakes in gray cast iron act as built-in solid lubricants, providing natural chip-breaking properties and reducing tool wear. Here are chart about the machinability of gray cast iron:

Top Grey Cast Iron Machined Parts & Case Studies


Cnc Machining processes such as cnc milling, turning and Gantry mill machining are today considered the most economic way to make Cast Iron prototypes. Sometimes, however, certain non-machiningable materials are needed, and sometimes sand casting is the only option. Our company has rich experience making Cast Iron concept models and precise functional components. Understanding the properties of different Cast Iron alloy, with lots of testing and experimentation with pre-heating, tool paths and other factors, we are able to minimize deformation on Cast Iron alloy. Be-cu prototyping company provides a range of solutions for the machining of Cast Iron parts.
