Milling Machine The milling machine has always been one of the most versatile machine tools used in industry (Fig. 5). Operations such as milling, contouring, gear cutting, drilling, boring, and reaming are only a few of the many operations which can be performed on a milling machine. The milling machine can be programmed on three axes:
Milling Machines A milling machine is a power driven machine that cuts by means of a multitooth rotating cutter. The mill is constructed in such a manner that the fixed workpiece is fed into the rotating cutter. Varieties of cutters and holding devices allow a wide rage of cutting possibilities.
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. Place a wooden pad or suitable cover over the table surface to protect it from possible damage.
In a milling machine, a multipoint cutter is rotating against the workpiece and material removed from the workpiece accordingly. In today's article, you will learn about the definition, parts, types, and operation of a milling machine, also at the end of the article, I will add the downloadable link of the PDF.
