A specialized piece of equipment used in automotive and engine rebuilding, this machine precisely reshapes the top surface of an engine’s cylinder head. This process ensures a flat, even surface for optimal sealing with the engine block and consistent combustion chamber volume across all cylinders. For example, it can be used to correct warping caused by overheating or to increase compression by reducing the volume of the combustion chamber.
Creating a perfectly level surface is critical for proper engine performance and longevity. This precision machining process helps restore or enhance engine power, improve fuel efficiency, and prevent issues like coolant leaks and compression loss. Historically, this process was performed manually, requiring significant skill and time. Modern computerized versions offer significantly improved accuracy and efficiency, contributing to higher quality engine rebuilds and manufacturing processes.
