Valve machining

The process of valve machining refers to the maintenance and repair of the valves themselves. Valves play a crucial role in combustion engines, as they are responsible for opening and closing the intake and exhaust ducts in the engine. They control the entry of the air-fuel mixture into the combustion chamber and the exit of the exhaust gases. Over time, valves can become worn or damaged by heat, pressure and exhaust gases. Valve machining involves grinding or replacing the valves to restore their shape and surface finish so that they seal effectively for optimum engine performance. This also includes machining the valve stems and guides to ensure that the valves operate accurately and without excessive clearance.
