What is bed ways in lathe?

In lathe machining, "bed ways" refer to the precision-ground surfaces on the lathe's bed that guide and support the movement of the carriage and tailstock. These ways are critical for ensuring accurate positioning and stability during the machining process. Typically made from hardened steel or cast iron, bed ways are designed to minimize friction and wear, allowing for smooth operation of the lathe components. Proper maintenance of bed ways is essential for achieving high precision and extending the lathe's lifespan.
