CI castings produced today are more advanced than they were used to be 20 years ago. Gray iron Castings Company is now manufacturing lighter, durable, and more affordable. Moreover, CI castings can be good alternative to steel castings as they face extreme pressure to cut costs. But the engineers have to determine the precise tooling for CI machining operations. For this, they need to understand the distinct range of cast irons and their level of strength, machinability, and cost. They also need to consider the cast iron complexities.
The process used for formation of castings generates microstructures with properties that vary between its internal body and a part’s surface. In this post, we bring few modern CI casting types from which iron casting manufacturing foundries can make selection and produce different castings:
- Vermicular cast iron that is having second name- compacted graphite iron, provides greater strength and lesser weight unlike gray iron. These castings are ideal for components that require mechanical and thermal stress. Manufacturers from auto industry are using this material for producing cylinder heads and brake components.
- Gray iron castings are usual and cheaper ones among all other casting types. Due to presence of carbides, these casting types offer excellent vibration damping properties and make them perfect choice for engine parts.
- Nodular ductile cast iron- these materials comprise of spheroid nodular graphite particles and have got high ductility, extreme wear resistance, good fatigue strength, high modules of elasticity, and thus, these have been best choice for making transmission housings and wheel suspension parts in the heavy equipment and auto industries.
Casting makers cannot survive with just single cutter. To bring successful results, they need to use different sized cutters that can handle both wet and dry conditions. However, milling cutter seems cost saving and multiple materials cutter that can fits in your standards. Still you need to consider the surface type that you are going to cut, and question yourself about the shape, wall thickness, clamping, etc.
Machine tools are critical and one should select the best. During machining of CI materials, the dynamic load is generally higher. In such case, your selected machining tools need to be robust and provide high stability and high power during operation.
In the end note, with several variables to consider, for enhanced productivity and predictability of CI machining efforts, you must work closely with your gray iron castings company and check on its moves.
