Equipment used in various industries, is assembled from a large number of precision parts, standard parts, chassis, chassis together. In the heart of precision parts machining process does not allow the slightest mistake, otherwise it will not work properly causing equipment precision machining is strictly controlled under ambient conditions, the use of precision machine tools and precision measuring tools and measuring instruments to achieve. Machining accuracy and more than 0.1 mm, said ultra-precision machining. In the automation equipment industry, mainly for precision machining processing machinery control equipment in the framework of precision components, such as hydraulic and pneumatic servo mechanism with precision parts, gyroscope, housing, air, liquid and floater floating bearing assemblies and so on. Complex precision parts, small stiffness, demanding precision, and difficult to process a large proportion of the material. Precision machining process effect are: geometry and mutual position of parts ① millimeter accuracy or angle seconds; ② part or feature limits of dimensional tolerances in mm; ③ parts of the surface micro-roughness (surface roughness average height difference) less than 0.1 mm; ④ with each other accessories to meet the power requirements; ⑤ some parts but also to meet the exact requirements of the mechanical or other physical characteristics, such as the float gyroscope torsional stiffness of the torsion bar, flexible element stiffness coefficient.
