A lathe bed is the main component of a lathe machine, providing a stable and rigid foundation for the entire setup. It is typically made from cast iron or steel, designed to absorb vibrations and maintain accuracy during machining operations. The bed features precision-ground surfaces that guide the movement of the carriage and tailstock. The lathe bed supports various parts, including the headstock, tailstock, and carriage, which hold and manipulate the workpiece. Proper alignment and leveling of the lathe bed are crucial for achieving precise cuts and finishes, making it an essential element in machining processes involving metalworking and woodworking.
