Horizontal Milling Machine

Horizontal Milling Machine
Figure 2 shows the main features of a Plain Horizontal Milling Machine.
Their functions are :-
a. ColumnThe column houses the spindle, the bearings, the gear box, the clutches, the shafts, the pumps, and the shifting mechanisms for transmitting power from the electric motor to the spindle at a selected speed.
b. KneeThe knee mounted in front of the column is for supporting the table and to provide an up or down motion along the Z axis.
c. Saddle The saddle consists of two slideways, one on the top and one at the bottom located at 90º to each other, for providing motions in the X or Y axes by means of lead screws.
d. TableThe table is mounted on top of the saddle and can be moved along the X axis. On top of the table are some T-slots for the mounting of workpiece or clamping fixtures.
e. Arbor The arbor is an extension of the spindle for mounting cutters. Usually, the thread end of an arbor is of left hand helix.
