THE HISTORY. Milling machines were originally developed to speed up hand-filing. They first appeared in the early 1800s (1814-1818), although it's difficult to trace the exact history due to the fact that there was a lot of development going on in small shops at the time.

The knee is a massive casting that rides vertically on the milling machine column and can be clamped rigidly to the column in a position where the milling he
A milling machine is one of the essential tools to have in a metal workshop. Most of the tool jobs require a milling machine rather than using a lathe. Where a lathe machine works in a direction and has no versatile application from both axis, the milling machine can do much better. Unlike a lathe, the milling machine has a dynamic, horizontal ...

Milling is the machining process in which the removal of metal takes place due to the cutting action of a rotating milling cutter.In a milling machine, the cutter is rotating due to workpiece is fed against it.This machine can hold more than one tool at a time. The cutter rotates at high speed, and because of the many cutting edges, it removes metal at a very fast rate.
RAM-TYPE MILLING MACHINE The ram-type 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 ram-type milling machines are the universal milling machine and the swivel cutter head ram-type milling machine.

The operation of rotating the job through a required angle between two successive cuts is termed as indexing. This is accomplished with the help of a milling attachment known as dividing head, which is an accessory to the milling machine. It helps to divide the job periphery into a number of equal divisions, i.e., square, hexagonal octagonal, etc.
