CNC machining can be used to manufacture several important components of automobile internal combustion engines. For example, a large aluminum block can be processed into an engine block (or cylinder block). The metal structure includes an engine cylinder, and the movable piston moves up and down in the cylinder.
Although programming a CNC machine is a time-consuming process and requires a high level of skill, once it is prepared, the machine can execute its instructions without assistance. This means that multiple engine blocks can be processed continuously without significant increase in labor.
The cylinder head is a part that surrounds the cylinder above the cylinder block, and is usually produced by CNC machining technology.
