What happens here
The next stage is cylinder honing, where the piston bores within the engine block are finished. This is achieved using a specialized cylinder hone machine, which uses a rotating and reciprocating tool head in a bath of coolant. The machine ensures a precise cross-hatch pattern and a specific surface finish in each cylinder, which is vital for proper piston ring seating and oil retention. Each block has a unique target for bore size and taper, which the machine precisely achieves. Workers move the blocks using overhead hoist systems.
Goal: Finish cylinder bores to precise specifications for optimal piston performance.
