While dedicated transfer lines are ideal for mass production of a single valve type, many manufacturers require flexibility to produce smaller batches of different valve designs. This is where a flexible manufacturing cell (FMC) excels. The key to a flexible cell is the use of standard CNC machines and robots that can be quickly reprogrammed for new part geometries, rather than dedicated, fixed-automation machinery.
The core of such a cell often includes a CNC lathe for machining and grooving, a grinding machine for the stem and seat, and a robot that moves parts between machines, a central pallet, and a coordinate measuring machine (CMM). Quick-change fixtures and tooling are essential to reduce changeover time from hours to minutes. The cell is managed by a central computer that controls the flow of parts and programs. This setup allows a manufacturer to produce a wide variety of valves for different engine platforms—from passenger cars to heavy-duty trucks—on the same equipment, maximizing asset utilization and responding quickly to market demands.
