Select the right cutting speed, rpm, and rate of feed for the job. Cut the stock using the cross feed or longitudinal feed controls. Turn off the machine before removing the stock. Note: There are several other operations that can be done using a vertical milling machine.
On some universal knee and column milling machine, the feed is obtained by turning the speed selection handle until the desired rate of feed is indicated on the feed dial. Most of the milling machines have a rapid traverse lever that can be engaged when a temporary increase in the speed of the longitudinal, transverse or vertical feeds is required.
Along with the type of milling machine, it has to be specified with its size. Commonly size of a typical milling machine is selected as given below: 1. Size of worktable with its movement range table length x table width like 900 x 275 mm. Table movements: Longitudinal travel x Cross x Vertical
vertical and cross feed adjustment while the worktable can be either hand or power driven at the operators choice. SAFETY RULES FOR MILLING MACHINES Milling machines require special safety precautions while being used. These are in addition to those safety precautions described in Chapter 1. Do not make contact with the revolving cutter.
A milling machine is basically used for shaping, routing, boring, and drilling metals and other solid materials. Generally there are two categories of the milling machine which include the vertical type and the horizontal type. In order to optimize the capacity of the milling machine, it is essential to identify the appropriate milling machine type for specific tasks.

The table had a working surface of 14quot; x 5quot; (the early, rather lighter machines had a shorter 12inch long table) and carried two T slots with a coolantdrain reservoir at its righthand end. Quickaction lever feed was fitted to all three directions of movement with screw feed to the cross and vertical travels and adjustable stops on all axes.
Quill Feed Hand Lever The saddle engages the slide on the top of the knee and can be moved in and out by turning the cross traverse handle. The saddle supports the table. Saddle locks lock the saddle at a given position. vertical milling machine parts and functions;
A vertical miller is used to shape metals such as mild steel and aluminium. It can also be used to shape plastics such as perspex and nylon. Full size milling machines such as the one shown below are powerful but also very accurate/precise.
