FIELD: process engineering.
SUBSTANCE: cylinder head cast blank has sealing surface 2 designed to be fitted on appropriate sealing surface on cylinder block. Said sealing surface 2 comprises combustion chamber zone 3 and features, as-cast, machining tolerance (Dz2) compared with rated thickness (Dn) after milling. Tolerance (Dz3) for machining a section of sealing surface 2 in combustion chamber zone 3 makes not over 15% of tolerance (Dz2) for machining sealing surface in remaining zone. Cylinder head in combustion chamber zone features the structure corresponding to casting structure in sealing surface zone prior to its milling.
EFFECT: optimised tolerable load on cylinder head.
