The Milling Machine uses a rotating milling cutter to produce machined surfaces by progressively removing material from a work piece. The vertical milling machine also can function like a drill press because the spindle is perpendicular to the table and can be lowered into the work piece. THE CONTROLS START/STOP
The ramtype milling machine is characterized by a spindle mounted to a movable housing on the column to permit positioning the milling cutter forward or rearward in a horizontal plane. Two popular ramtype milling machines are the universal milling machine and the swivel cutter head ramtype milling machine. UNIVERSAL RAMTYPE MILLING MACHINE
Mill Drill Machines are used for accurately boring, drilling, milling or tapping into a workpiece.

![What Is a Knee Mill How Do They Work? [Full Guide] Lathe Matters](/obyq6xg/118.jpg)
A knee milling machine is a form of standing machine that is rather straightforward. It can move along the vertical Yaxis and the horizontal Xaxis. In other words, the worktable travels along the machining axis exactly like the workpiece itself. Bridgeport mills are another name for knee mills on occasion.
Usually, a rotary table is placed between the bed and the vertical milling head in a vertical milling machine, which allows the spindle to tilt at a certain angle for milling inclined surfaces. The vertical milling machine can also be used for boring holes. Milling Machine Accessories. b) Tilting worktable. c) Rotary worktable.
It is used to control the longitudinal ( left and right), transverse ( in and out) and vertical (up and down) feeds. To get the desired rate of feed on the machine, the feed selection lever is positioned as indicated on the feed selection plates.
