Machining

    Machinery refers to the general term for machines and institutions. Machinery is a tool device that can help people reduce the difficulty of work or save effort. Items such as chopsticks, brooms, and tweezers can all be called machinery. They are simple machinery. The complex machinery is composed of two or more simple machinery. These more complicated machines are usually called machines. From the point of view of structure and movement, there is no difference between a mechanism and a machine, and it is generally called a machine. Precision machining mainly includes precision turning, precision boring, precision milling, precision grinding and grinding. The technological effects of precision machining are: ①The geometric shape and mutual position accuracy of the parts reach the micron or arc second level; ②The limit or feature size tolerance of the part is below micron; ③The surface microscopic unevenness of the part (the average height difference of the surface unevenness) Less than 0.1 microns; ④Mutual parts can meet the requirements of matching force; ⑤Some parts can also meet the requirements of precise mechanics or other physical characteristics, such as the torsional stiffness of the torsion bar of the float gyroscope and the stiffness coefficient of the flexible element.

    Precision machining is achieved by using precision machine tools and precision measuring tools and measuring instruments under strictly controlled environmental conditions. The machining accuracy reaches and exceeds 0.1 micron, which is called ultra-precision machining. In the aerospace industry, precision machining is mainly used to process precision mechanical parts in aircraft control equipment, such as precision matching parts in hydraulic and pneumatic servo mechanisms, gyroscope frames, shells, air and liquid bearing components and Float and so on. The precision parts of aircraft have complex structures, low rigidity, high precision requirements, and difficult-to-process materials account for a large proportion. Which machining method is the most accurate machining method? Dongguan precision machining manufacturers tell you. It is a grinding method. Abrasive particle diameter, cutting force and cutting heat can be precisely controlled, so it is the highest precision machining method in precision machining technology.
