Bed Milling Machine. A third type of milling machine is bed. Bed milling machines are characterized by the use of a pendant. They still have a spindle that holds the cutting tool, but the spindle is secured to a pendant. The pendant can be raised or lower so that the cutting tool can reach the workpiece.
Duplex milling machine: In this type, the spindle travels both vertical and horizontal directions. Triplex milling machine: In the triplex type, the spindle moves in all three directions along X, Y, and Z-axis. Planner milling machine: The types of milling machines are widely used for facing operations in mass production.

type, and planer-type milling machines. Most machines have self-contained electric drive motors, coolant systems, variable spindle speeds, and power-operated table feeds. (1) Knee-type Milling Machines. Knee-type milling machines are characterized by a vertical adjustable worktable resting on a saddle supported by a knee.
The milling machines are classified according to the general design of the machine. 1. Column and knee type a) Plain milling machine b) Universal milling machine c) Omniversal milling machine d) Vertical milling machine 2. Table type milling machine 3. Planer type milling machine 4. Special type milling machine
In the case of bed-type milling machines, the worktable is placed on the bed. To allow longitudinal motion in a bed-type milling machine, the knee is omitted. #10. Rotary Table Milling Machine. Rotary tables milling machines have the ability to perform up to 2D and 2.5D machine cycles at or around the end of the cylinder. When the machine is ...
