The definition of a machine tool, if you look in the dictionary, is a powered machine used for cutting or shaping or finishing metals or other materials. This actually applies to a wide variety of tools such as a broach, drill, gear shaper, hobbing machine, lathe, milling machine, shaper, and grinder.
Of course this definition doesn’t really describe the usefulness of these type of tools. So we’ll try to do just that in this article.
Most machine tools, also by definition, are tools that are tools that use a power source. In other words, not operated manually. But there are some tools that are considered machine tools that are operated by hand.
