Machine tools are machines for cutting metals. The most important of machine tools used in industry are lathes, drilling machines, and milling machines. Other kinds of metal working machines are not so widely used in machining metals as these three.
Lathe
A lathe is a machine tool for cutting metal from the surface of a round work fastened between the two lathe centers and turning around its axis. The lathe is commonly called the father of the entire machine tool family. For turning operations, the lathe uses a single-point cutting tool which removes metal as it travels past the revolving workpiece, 2.4 Turning operations are required to make many different cylindrical shapes, such as axes, gear blanks, pulleys, and threaded shafts,2.1 Boring operations are performed to enlarge, finish, and accurately locate holes.
Drilling and drilling machines
Drilling is performed with a rotating tool called a drill, 2.2 Most drilling in metal is done with a twist drill. The machine used for drilling is called a drill press. Operations, such as reaming and tapping, are also classified as drilling. Reaming consists of removing a small amount of metal from a hole already drilled, 2.2 Tapping is the process of cutting a thread inside a hole so that a cap screw or bolt may be threaded into it.
Milling machine
The milling machine is a machine that removes metal from the work with a revolving milling cutter as the work is fed against it. Milling cutters are made in many styles and sizes. Some have as few as two cutting edges and others have 30 or more. Milling can produce flat or angled surfaces, groves,slots, gear teeth, and other profiles, depending on the shape of the cutters being used.
Shaper and planer
Shaper and planer are machines that produce flat surfaces with a singlepoint cutting tool. In shaping, the cutting tool on a shaper reciprocates or moves back and forth while the work is fed automatically towards the tool.In planning, the workpiece is attached to a worktable that reciprocates past the cutting tool. The cutting tool is automatically fed into the workpiece a small amount on each stroke.
Grinder
Grinder is a machine that makes use of abrasive particles to do the cutting. Grinding operations may be classified as precision or nonprecision,depending on the purpose. 2.3 Precision grinding is concerned with grinding to close tolerances and very smooth finish. Nonprecision grinding involves the removal of metal where accuracy is not important.
