Milling machine feed mechanism United States Patent 2473596 Abstract: This application is a divisional application of Serial Number 414,962, filed October 14, 1941, now Patent No. 2,338,121, issued January 4, 1944.
The horizontal and vertical feed control mechanism of the X6132 horizontal universal milling machine table is shown in the figure. Handle 1 has upper, lower, front, rear and middle five working positions. When the handle 1 is moved forward and backward, the drum is driven by the ball at the front of the handle to move left and right axially.

• Most milling machines are equipped with power feed for one or more axes. Power feed is smoother than manual feed and, therefore, can produce a better surface finish. Power feed also reduces operator fatigue on long cuts. On some machines, the power feed is controlled by a forward reverse lever and a speed control knob.
