Passenger vehicle cylinder blocks and heads are typically made of cast aluminum alloy, while commercial vehicle cylinder blocks remain primarily cast iron. These materials have low hardness, are prone to built-up edge (BUE) formation, and produce high levels of burrs. Machining processes are characterized by long cycle times, numerous dimensional features, and components sensitive to temperature changes, with critical bores requiring high dimensional accuracy and strict CPK (Process Capability Index) compliance. Primary operations include face and hole machining, with additional requirements for knurling and bimetal machining. Driven by extreme efficiency demands, a wide range of custom composite tools are used to support high-volume, automated production.
