A milling machine is a machine tool usedto machine solid materials. Milling machines are oftenclassed in two basic forms, horizontal and vertical, which

refer to the orientation of the main spindle. Both typesrange in size from small, bench-mounted devices toroom-sized machines. Unli e a drill press, which holdsthe wor piece stationary as the drill moves a!ially topenetrate the material, milling machines also move thewor piece radially against the rotating milling cutter,which cuts on its sides as well as its tip. "or piece and

cutter movement are precisely controlled to less than#.##$ in %#.#&' mm(, usually by means of precisionground slides and leadscrews or analogous technology.Milling machines may be manually operated,mechanically automated, or digitally automatedvia computer numerical control %)*)(.Milling machines can perform a vast number of

operations, from simple %e.g., slot and eyway cutting,planing, drilling( to comple! %e.g., contouring,diesin ing(. )utting fluid is often pumped to the cuttingsite to cool and lubricate the cut and to wash away theresulting swarf.

In this shop various machines are there toperform above operation these are Drilling (0oring ( ,rinder machines .

?!#I$U $-"#!TI$NDrilling is a cutting process that uses a drill bit to cut orenlarge a hole in solid materials. The drill bit is a multipoint,end cutting tool. It cuts by applying pressure and rotation tothe workpiece, which forms chips at the cutting edge.

0$#IN,+n machining, boring is the process of enlarging a hole

that has already been drilled %or cast(, by means ofa single point cutting tool %or of a boring head containingseveral such tools(, for e!ample as in boringa cannon barrel. Boring is used to achieve greateraccuracy of the diameter of a hole, and can be used tocut a tapered hole.
