Machine-tools

There are various machine-tools to shape metals and other materials. Machine-tools with electrical drive are faster and more accurate than hand tools. They are an important element in the development of mass-production processes. All machine-tools have facilities for holding both the workpiece and the tool, and for accurately controlling the movement of the cutting tool relative to the workpiece. Most machining operations generate large amounts of heat, and there are cooling fluids (usually a mixture of water and oil) for cooling and lubrication. 

Machine-tools usually work materials mechanically but there are many other machining methods in machinery. They are chemical machining, spark erosion to machine very hard materials to any shape by means of a continuous high-voltage spark between an electrode and a workpiece. Some machining methods include drilling with the use of ultrasound, and cutting by means of a laser beam. Numerical control of machine-tools and flexible manufacturing systems give a possibility to complete systems of machine-tools to be used flexibly for the manufacture of a range of products.

There are many types of machine-tools, such as a lathe, drilling and boring machines, grinders, shapes and planers, dies. Their application is wide; they are also different in size and function. For example, there are portable drills and radial drilling machines. 

The most important machine-tool is a lathe. Modern lathes are often under numeral control. Lathe has many operations such as drilling, reaming.
