In shield tunneling construction, scraper tools such as cutters and blades are typically fixed to the cutterhead using a bolted connection. From the perspectives of manufacturability and maintainability, the housing components—equipped with internal threads—are made from low-carbon alloy steel. These housings are then welded directly to the cutterhead’s baseplate, allowing for easy replacement if the housing becomes damaged. Considering both material costs and construction processes, low-carbon alloy steel remains the preferred material for manufacturing these cutterhead housing components today.
