Vertical knee mills like the Bridgeport Mill Series 2, also known as vertical milling machines or knee-type milling machines, are widely used in the metalworking industry for various milling operations. These machines are equipped with a vertically oriented spindle that is mounted on a knee, allowing the spindle to move up and down along the Z-axis.

Vertical knee mills offer versatility and flexibility in milling operations. They can perform tasks such as face milling, end milling, drilling, and boring on a variety of workpieces. The knee mechanism on a Bridgeport Mill Series 2 provides precise vertical movement, allowing for accurate positioning of the milling cutter.

One of the key features of vertical knee mills is their ability to accommodate large workpieces due to their robust construction and wide work tables. They can handle both small and large-scale projects, making them suitable for diverse applications.

Vertical knee mills like the Bridgeport Mill Series 2 are often equipped with digital readouts (DROs) or CNC control systems, enhancing precision and productivity. The DROs provide accurate measurement and positioning feedback, while CNC controls automate the milling process, allowing for complex operations and improved efficiency.
