What is the function of the knee on a milling machine?

The knee on a milling machine serves a crucial role by providing support to the table and allowing for vertical movement. This component is positioned between the table and the machine's bed, providing a mechanism for adjusting the height of the table, which in turn affects the positioning of the workpiece in relation to the cutting tool. The vertical movement facilitated by the knee enables the operator to easily raise or lower the table to achieve the desired cutting depth or to accommodate different sizes of workpieces. This adjustment is essential for precision milling operations, as it allows for controlled and accurate cutting actions on the material being machined. The knee's design and functionality are critical for achieving the right setup and ensuring effective milling operations.
