Large Head Lathe, formally known as a "Floor Type Lathe" is a highly versatile machine tool engineered to handle workpieces of widely varying diameters. Its defining feature is a removable section ("the gap") in the bed, directly in front of the headstock. By unbolting and sliding out this section, the lathe's swing capacity is dramatically increased, often by several inches. This allows a single machine to perform facing, boring, and turning on exceptionally large-diameter components like flywheels, large gears, or rotors that would be impossible on a standard lathe of...
