 Machinery Tool is a tool used for cutting, also known as the cutting tool. Cutting tools include both general tools, but also abrasive. Most machine tools are used, but there are also hand use. As used in machinery for cutting tool basically metal, so the "tool" to understand the general term for the metal cutting tools. Wood cutting tool is called woodworking tools. Tool development in the history of human progress plays an important role. China as early as 28 BC, before the 20th century, there had been copper brass cone and the cone, drills, knives and other copper knives. Warring States period (third century BC), the master of the carburizing technology, manufacturing a copper tool. Then drill and saw, with modern drilling and sawing flat has some similarities. 
 Tool by the workpiece surface can be divided into five categories. Processing of various outer surface of the tool, including turning tools, planer, cutter, knife and rasp the outer surface of pull, etc.; hole cutting tools including drill bits, reaming, drilling, boring tools, reamers and the inner surface of the broach, etc.; threading tools, including taps, dies, thread cutting head automatically open and close, thread turning and thread milling cutters, etc.; gear cutting tools including hobs, gear shaper cutters, shaving cutter, bevel gear cutting tools, etc.; cutting tools, including inserts tooth circular saw blades, band saw, bow saw, cut off the lathe and saws and so on. In addition, combination tools. 
 And the corresponding movement pattern by cutting the blade shape, the tool can be divided into three categories. Generic tools, such as turning tools, planer, cutter (not including forming turning tools, shaping and forming cutter planer), boring tools, drill, reamer, reamers and saws, etc.; forming tool, such tool edge the workpiece to be machined with a cross section with the same or nearly the same shape, such as forming turning tools, forming planing, shaping cutters, broaches, tapered reamers and other cutting tools of various Screw; develop into a processing tool is the gear generating method tooth surface or similar parts, such as hobs, gear shaper cutters, shaving cutter, bevel gear and bevel gear cutter planer and so on. 
 Working part of the tool is part of the generation and processing chips, including the blade, so that chip off pieces of the rope structure or volume, or capacity storage chip chip space, cutting fluid and other structural elements of the channel. Some parts of the tool is cutting some of the work, such as turning, planing, boring and milling, etc.; some parts of the tool's work contains some of the cutting part and calibration, such as drills, reamer, reamer, inner surface of the pull knife and tap and so on. The role of the cutting part of the chip with the blade removed, the calibration part of the role is to refinish the surface has been processed and guide the cutting tool. 
 Usually when high hardness, wear resistance is also high; high bending strength, impact toughness is high. However, the higher the hardness, the bending strength and toughness lower. High-speed steel for high bending strength and toughness, and good machinability, the modern is still the most widely used tool material, followed by carbide. Polycrystalline cubic boron nitride for cutting of high hardness such as hardened steel and hard cast iron; polycrystalline diamond for cutting non-ferrous metals, and alloys, plastic and glass steel; carbon tool steel and alloy tool steel is only for the file, dies and taps and other tools. Carbide indexable inserts are now coated with a chemical vapor deposition of titanium carbide, titanium nitride, aluminum oxide layer or composite layer of hard hard. Being developed not only the physical vapor deposition method can be used for carbide cutting tools can also be used for high-speed steel cutting tools, such as drills, hobs, taps and milling cutters and so on. Hard coatings as chemical diffusion and thermal conduction impeding the barrier so that the tool wear in cutting the slower pace of life and non-coated blade coating increased compared to about 1 to 3 times. 
 As the high-temperature, high pressure, high speed, and corrosive fluids in the working parts, the application of more and more difficult to machine materials, cutting the level of automation and accuracy of processing become increasingly demanding. To meet this situation, the tool will be the development direction of development and application of new tool materials; the further development of vapor deposition coating technology tools, high-strength high-toughness matrix hardness of the coating deposited on a higher, better address tool material hardness and strength of the conflict between; further development of the structure of indexable cutting tools; improve manufacturing precision cutting tools, reducing the difference between product quality and make the best use of the tool.
