Which vertical milling machine component is labeled as 12?

The component labeled as 12 in a vertical milling machine being identified as the saddle is accurate. The saddle is a crucial part of the milling machine that supports the table and allows it to move in a horizontal direction. It is mounted on the knee of the machine and provides the necessary support for the table that holds the workpiece. The saddle’s movement is typically controlled by handwheels, enabling precise adjustments during milling operations.

In the context of milling machine operations, understanding the function and location of the saddle is essential for setup and machining processes, as it plays a fundamental role in positioning the workpiece effectively. The other components like the column, table, and ram also play significant roles but do not fulfill the specific functionality that the saddle does concerning the movement and stability of the table.
