Miller Machine
A milling machine removes material from a work piece by rotating a cutting tool (cutter) and moving it into the work piece. Miller Machine, either vertical or horizontal, are usually used to machine flat and irregularly shaped surfaces and can be used to drill, bore, and cut gears, threads, and slots. The vertical mill, or “column and knee” mill, is the most common milling machine found in machine shops today.
The general construction of this mill includes the quill, which moves vertically in the head and contains the spindle and cutting tools. The knee moves up and down by sliding parallel to the column. The column holds the turret, which allows the milling head to be positioned anywhere above the table. Hand wheels move the work table to the left and right (X axis), in and out (Y axis), in addition to moving the knee, saddle, and worktable up and down (Z axis)
