Milling is a process where unwanted materials are removed from a workpiece by using rotating cutters. Although the working principle is simple, the machine can be used to perform various milling operations, including angular milling, thread milling, and gear milling, just to name a few. These are the functions of a milling machine.
Drilling machine operation Reaming Boring Counter boring Counter sinking Spot facing Tapping 16. Reaming It is a process of smoothing the surface of drilled holes with a tool. Tool is called as reamer. Initially a hole is drilled slightly smaller in size. Drill is replaced by reamer. Speed is reduced to half that of the drilling.

A milling machine has Column and Base, Knee, Saddle and Swivel Table, Power Feed Mechanism, Table, Spindle, Over Arm/ Overhanging Arm, Arbor Support, and Ram. Column and base provide supports for the other parts of a milling machine. There is an oil reservoir and pump in the column to lubricate the spindle. The column rests on the base and …
Read: Understanding lathe machine. Milling head: The milling head is the upper part of a vertical mill machine. It consists of spindle, driving motor and other controlling mechanisms. Ram: The milling machine part can move transversely (in and out) on the column by a hand level.
the help of feed mechanism the lathe machine operates manually. Lathe Machine Definition: A lathe machine is a machine tool which is used to remove metals from a workpiece to give a desired shape and size. Lathe Machines are used in metalworking, woodturning, metal spinning, thermal spraying, glass working, and parts reclamation.

Milling and Milling Machine Milling and Milling Machine Milling Machines Milling Machines • The basic components of these machines are as follows: • Worktable: on which the workpiece is clamped using T-slots. The table moves longitudinally relative to the saddle. • Saddle: supports the table and can move in the transverse direction. • Knee: supports the saddle and gives the …
Knee-Type Milling Machines The vertical milling machine, found in most shops, is more widely used than the horizontal milling machine. It is an easy machine to set up and operate. The name "knee-type " has been adopted for this type of milling machine, because it features a knee which mounts the work table and travels vertically along the guide ...
