Machining Processes and Machine Tools

Machining is represented as the process in which an excessive amount of substance is eliminated from the particular element in the form of pieces. In machining, cutting tools such as rotary tools, lathe, drill press, grinder, chop saw, welders, and many more are applied to get the desired shape. As compared to other manufacturing processes, machining is precise and versatile.
