A knee type milling machine is a fundamental machine tool distinguished by its vertically adjustable worktable mounted on a "knee" casting. This knee moves precisely up and down a fixed column via a screw mechanism, enabling accurate Z-axis positioning crucial for diverse milling operations.
The core principle involves a rotating milling cutter removing material from a workpiece secured to the table. The adjustable knee mechanism allows controlled vertical movement (Z-axis), while the table provides longitudinal (X-axis) and transverse (Y-axis) travel. This 3-axis control facilitates complex machining of flat, angular, and contoured surfaces.
Since their development in the late 19th century, knee-and-column mills revolutionized machining. The iconic Bridgeport design (1938) popularized the turret style. While CNC machining centers dominate high-volume production, knee mills remain indispensable for flexibility, ease of use, and cost-effectiveness in job shops, schools, and repair facilities worldwide.
