It is well known that in the machinery manufacturing industry, milling machines have the role of other equipment can not be replaced. The development and role of milling machine in the whole manufacturing industry can not be ignored.
In 1818, Whitney developed the first milling machine. By 1862, US engineer Joseph Brown developed the first universal milling machine. Milling machine has experienced from a simple processing equipment to today with a multi-functional high-intelligent processing center and combined with other equipment, integrated high-precision high-intelligent composite processing heart; from ordinary machine tools to high-performance, high intelligence, environmental protection integrated machine.This is not only experienced a simple mechanical transformation, but also in the system, electrical appliances, transmission structure, etc. has undergone tremendous changes.In 1952, the Massachusetts Institute of Technology in a vertical milling machine on the installation of three-axis automatic feed system and to achieve three-axis automatic control, which is recognized as the world's first CNC milling machine. It is used in industrial and military have reached a precision and efficiency in the traditional manufacturing sector can not be achieved. For example, in the manufacture of aircraft wings, Parsons Corporation comprehensive use of digital technology and a variety of processing technology, so that the wing reached the highest level of accuracy. Therefore, industrial development should not only emancipate the labor force but also emancipate the productive forces. The development of science and technology is the first productive force.
In industrial manufacturing, lathes, milling machines, grinding machines, boring machines, planers, drilling machines are essential in the traditional industrial machinery and equipment, but also the basis for industrial manufacturing. To leave these foundations, industrial manufacturing is completely impossible. The lathe is the workpiece to do the rotary motion, so it is suitable for machining the shaft type workpiece. Milling machine is a tool to do rotary motion, so it is suitable for processing some linear motion of the workpiece. Grinding machine is mainly used to process the surface of the workpiece to improve the accuracy of the workpiece surface and finish. Boring machine is mainly used for processing holes in the workpiece. Planer is mainly used to process straight parts of the workpiece. The role of these machines are different, the choice of processing technology is not the same. Especially the milling machine, it not only has its own advantages, but it can also use some accessories to process different parts. Such as dividing head, turntable, plugs are all necessary accessories for milling machines.
Types of milling machines:
With the development of industry, people have developed a lot of types of milling machines. Including the vertical milling machine, horizontal milling machine, copying milling machine, universal milling machine, drilling and milling machine, turret milling machine, lifting table milling machine, Longmen milling machine, tool milling machine and instrument automatic milling machine, CNC milling machine, CNC machining center, composite machining center.
From the original single workpiece rotation and tool rotation to the tool and the workpiece at the same time rotation. The first engineers developed by the workpiece and the tool at the same time the rotation is more mature results in the lathe on the basis of the transformation of the cyclone milling. At that time mainly in order to improve the screw and worm processing efficiency. Cyclone milling machining accuracy is not high, only rough processing, but also late finishing. The current composite processing center can solve this problem, not only high precision and efficiency is also high. Coupled with the rotary table, almost solved the complex parts, long duration, high difficulty, low yield of integrated issues, but also by the traditional rely on human technology to rely on scientific and technological capabilities. This solves the world industrial manufacturing in the major problems, to the global industrial, agricultural, military, science and technology development brings great convenience. The most critical of these developments is the development of milling technology, but also a major revolution in milling machines, but also a historic breakthrough.
