Machine tool (English name: cnc machine tool) refers to a machine that manufactures a machine, also known as a machine tool or a machine tool, and is habitually referred to as a machine tool. Generally divided into metal cutting machine tools, forging machine tools and woodworking machine tools. There are many methods for processing mechanical parts in modern machinery manufacturing: in addition to cutting, there are casting, casting, welding, stamping, kneading, etc., but for turning and milling composite parts that require high precision and fine surface roughness, general All need to use the cutting method for final processing on the machine tool. Machine tools play a serious role in the modernization of the national economy. The lathe is a machine tool that primarily uses a turning tool to turn a rotating workpiece. On the five-axis CNC lathe, drills, reamers, comparison tools, taps, dies and knurled objects can also be used for corresponding processing. Lathes are mainly used for machining shafts, discs, sleeves and other workpieces with reversing surfaces. They are a type of machine tool widely used in machinery manufacturing and repair factories.

The center of industrial technology development has quietly moved from Britain to the United States since the nineteenth century. Among those who have taken the prestige of British technology into the past, Whitney is one of the best. Whitney was brilliant and insightful, and he first developed the system as a mass-produced replaceable component. Still very vivid today, Tenet Engineering Company, as early as the 1840s, successfully developed a turret type hexagonal lathe. This kind of lathe came out following the messiness and refinement of the workpiece. In this kind of lathe, there is a winch, and all kinds of tools are installed on the winch. In this way, by rotating the turret that fixes things, You can turn things to the desired position. Following the invention of the electric motor, the machine tool began to use electric motors to drive centrally, and then widely used independent electric motors to drive. In the early twentieth century, in order to process workpieces, fixtures and thread processing tools with higher precision, the coordinate mantle bed and thread grinder were successively created. In order to get accustomed to the demand for mass production in industries such as automobiles and bearings, it has also developed various automatic machine tools, profiling machine tools, modular machine tools and automatic production lines.
1900 entered a period of refinement. From the end of the 19th century to the beginning of the 20th century, a single lathe has gradually evolved into a milling machine, a planer, a grinder, a drilling machine, and so on. These primary machine tools have now been fundamentally finalized, thus making it clear for the fine machine tools and the production of mechanization and semi-automation in the early 20th century. condition. In the first 20 years of the 20th century, people first deployed coiled milling machines, grinders, and assembly lines. Due to the production requirements of automobiles, airplanes and their engines, there is an urgent need for sophisticated and automatic milling machines and grinders when machining large quantities of messy-shaped, high-precision and high-finish parts. Due to the advent of multi-helical cutters, the vibration and smoothness of single-edged cutters are fundamentally dealt with and the milling machine cannot be deployed because of the difficulty of unrolling, making the milling machine an important equipment for processing messy parts. Ford, known as the "father of automobiles" by the world, puts forward that cars should be "light, strong, reliable and cheap." In order to complete this policy, it is necessary to develop efficient grinders. For this reason, American Norton used emery and corundum to make large-diameter grinding wheels and heavy-duty grinders with large rigidity and corundum in 1900. The development of the grinder has brought the mechanical manufacturing technology into a new stage of refinement.
